PATENT NOTICE
U.S. Patents have been issued, or applied for, to protect the following design features:
Data Sensing and Processing Device (U.S. Patent no. 4,882,678), Ascent Rate Indicator (U.S. Patent no. 5,156,055).
CE
The CE mark is used to mark conformity with the European Union EMC directive 89/336/EEC. TUSA dive instruments
fulfill the required EU directives.
EN 13319 "Diving accessories - Depth gauges and combined depth and time measuring devices - Functional and
safety requirements, test methods" is a European diving depth gauge standard. The Element II is designed to comply
with this standard.
DECOMPRESSION MODEL
The program within the Element II simulates the absorption of nitrogen into the body by using a mathematical model.
This model is merely a way to apply a limited set of data to a large range of experiences. The Element II dive computer
model is based upon the latest research and experiments in decompression theory. Still, using the Element II, just
as using the Navy (or other) No Decompression Tables, is no guarantee of avoiding decompression
sickness, i.e. “the bends.” Every diver’s physiology is different, and can even vary from day to day. No machine
can predict how your body will react to a particular dive profile.

INTRODUCTION
Welcome to TUSA and thank you for choosing the Element II !
It is extremely important that you read this Owner's Manual in sequence and understand it
completely before attempting to use the Element II as a dive computer.
Remember that technology is no substitute for common sense, and a dive computer only
provides the person using it with data, not the knowledge to use it.
CONTROL BUTTONS
The Element II features three Control Buttons that allow you to select mode options and
access specific information. They are also used to enter Settings, activate the Backlight,
and acknowledge the Audible Alarm.
Throughout this manual they will be referred to as the M, A, and S buttons.
• Front/Left - Mode (M) button
• Front/Right - Advance (A) button
• Right/Side - Select (S) button

OPERATING MODES
The Element II features 3 Operating Modes, NORM (Fig. 1A)
which is used for Air and Nitrox SCUBA dives, GAUG (Fig. 1B)
used for SCUBA dives in which Nitrogen-Oxygen calculations
are not performed, and FREE (Fig. 2) used for activities that do
not use SCUBA.
> NORM Mode allows access to Fly, Desat, Log, and History
Modes, as well as entering settings.
> GAUG Mode is similar without access to Desat Mode.
> FREE Mode only allows access to specific Free Modes.
AUDIBLE ALARM
Most warning situations that activate the Audible Alarm while
operating in NORM or GAUG Mode cause the Element II to emit
1 beep per second for 10 seconds, or until the situation is
corrected, or it is acknowledged by momentarily pressing and
releasing the S button (less than 2 seconds).
After being acknowledged and the situation corrected, the Alarm
will sound again upon reentry into the warning situation, or entry
into another type of warning situation.
FREE Dive Mode has its own set of Alarms which emit 3 short
beeps either 1 or 3 times which cannot be acknowledged or set
Off.
11
Situations that will activate the NORM/GAUG 10 second Alarm include -
• Descent deeper than the Max Depth Set Point selected.
• Dive Time Remaining at the Set Point selected.
• Elapsed Dive Time at the Set Point selected.
• High PO2 of 1.60 ATA or the Set Point selected.
• High O2 of 300 OTU (single or daily exposure).
• Nitrogen Bar Graph at the segment Set Point selected.
• NORM/GAUG Ascent Rate exceeds 60 FPM (18 MPM) when deeper than 60 FT (18
M), or 30 FPM (9 MPM) at 60 FT (18 M) and shallower.
• Entry into Decompression Mode (Deco).
• Conditional Violation (above a required Deco Stop Depth for less than 5 minutes).
• Delayed Violation (above a required Deco Stop Depth for more than 5 minutes).
• Delayed Violation (a Deco Stop Depth greater than 60 FT/18 M is required).
• Delayed Violation (the Maximum Operating Depth of 330 FT/100 M in NORM, or
399 FT/120 M in GAUG, is exceeded).
• A Gas Switch would expose the diver to PO2 greater than 1.60 ATA.
A single short beep (which cannot be disabled) is emitted for the following -
• Upon completion of a battery change.
• Change from Delayed to Full Violation 5 minutes after the dive.
3 short beeps (which cannot be disabled) are emitted for the following -
• NORM/GAUG Ascent Rate is 51 to 60 FPM (15.1 to 18 MPM) when deeper than
60 FT (18 M), or 26 to 30 FPM (7.5 to 9 MPM) at 60 FT (18 M) and shallower.
• FREE Dive Elapsed Dive Time Alarm (3 beeps every 30 seconds if set On).
• FREE Dive Depth Alarms 1/2/3 (set sequentially deeper) - each 3 beeps 3 times.
12
• FREE Dive NiBG Alarm (Caution zone, 4 segments) - 3 beeps 3 times.
• Entry into Deco during a FREE Dive (Permanent Violation) - 3 beeps 3 times.
• Free Dive Mode Countdown Timer reaches 0:00 - each 3 beeps 3 times.
During the following NORM Dive situations, the 10 second continuous tone will be fol-
lowed by a 5 second steady beep that will not turn off when acknowledged -
• Ascending above a required Decompression Stop Depth for more than 5 minutes
(referred to as a Delayed Violation).
• Decompression requires a Stop Depth of 70 FT/21 M or deeper.
• Being on the Surface for 5 minutes after a Conditional Violation (Permanent Violation).
BACKLIGHT
> To activate the Backlight, while on the surface and during dives >> depress the S
button for 2 seconds.
• The Backlight will illuminate the display for button depression time plus the Duration
time set 0, 5, or 10 seconds.
(*The Backlight will turn Off if the button is held depressed for more than 10 seconds.)
• Press the button again to activate as desired.
NOTE: Extensive use of the Backlight reduces estimated Battery life.
Also, the Backlight does not operate during a Low Battery Condition
or when the Element II is connected to a PC.

POWER SUPPLY
The Element II uses (1) 3 volt CR2450 Lithium Battery which
should maintain operation for 1 year or 300 dive hours if 2
dives are conducted during each dive period. The Element II
checks battery voltage every 2 minutes while on the surface.
• If voltage of the Element II decreases to the Warning level
(2.75 volts), the Battery icon will appear on Surface display
screens (Fig. 3a) as an indication that the Battery should be
changed prior to commencing a series of dives.
• If voltage decreases to the Alarm level (2.50 volts), the
Battery icon and graphic BAT will flash for 5 seconds then
the unit will shut Off.
• Low Battery conditions are not displayed during dives. If a
Low Battery condition was not displayed prior to starting a
Dive, and a Low Battery Condition occurs during the dive,
there will be sufficient Battery power remaining to maintain
operation for the remainder of that dive.
• Upon surfacing, the Low Battery icon will be displayed. If
voltage was at the Alarm level (2.50 volts), the graphics
CHG and BAT will alternate for 5 seconds (Fig. 4a)
followed by shut down of the unit until the Battery is
changed.

PC INTERFACE
Interface with a PC (for data Upload and Download) is accom-
plished by connecting the Element II to a PC USB Port using the
USB Interface Cable avaiable as an optional accessory.
The PC Interface program, together with a USB Driver, is
downloadable from tusa.com. The Help portion serves as the
user manual and can be printed for personal use. The Settings
Upload portion is used to check the Element II's existing Settings
and for entering Time, Alarm, and other settings into the Element
II. The Download portion is used to retrieve Data that was
sampled during dives and stored in the Element II's memory.
The Element II checks for an External Access request once every
second while in Surface Mode. Checks are not made if the unit
is wet. For a connection to be made, the Interface Cable is
clipped onto the Element II's Data Port and plugged into a PC
USB Port. To establish the connection, the PC program must be
running.
When the connection is made, a PC screen appears on the
Element II displaying the graphic PC and a countdown for 2
minutes or until completion of the interface operation. Then
operation reverts to the Surface Main screen.

BAR GRAPHS
The Element II features 3 Bar Graphs >> NiBG, O2BG, and
ASC.
NiBG (Nitrogen Loading Bar Graph)
The NiBG (Fig. 6a) represents tissue loading of nitrogen, show-
ing your relative no decompression or decompression status. As
your depth and elapsed dive time increase, segments will add to
the NiBG, and as you ascend to shallower depths, the segments
will recede, indicating that additional no decompression time is
allowed for multilevel diving.
The NiBG monitors 12 different nitrogen compartments simulta-
neously and displays the one that is in control of your dive. It is
divided into a No Decompression (normal) zone, a Caution
zone (also No Deco), and a Decompression (danger) zone.
While you cannot provide a guarantee against the occurrence of
decompression sickness, you may choose your own personal
zone of caution based upon age, physique, excessive weight,
etc., to reduce the statistical risk.
NOTE: Displays associated with oxygen and the
O2BG will only appear if FO2 has been set at a
value other than 'Air' (e.g., a numerical value).
Fig. 6 - NiBG

17
M
A
S
Oxygen Bar Graph (O2BG)
The O2BG (Fig. 7a) represents oxygen accumulation, showing
the maximum of either per dive accumulated oxygen, or 24 hour
period accumulated oxygen.
As your oxygen exposure (accumulation) increases during the
dive, segments will add to the O2BG, and as saturation de-
creases, it will begin to recede, indicating that additional expo-
sure is allowed for that dive and 24 hour period.
Ascent Rate Indicator (ASC)
The ASC (Fig. 7b) provides a visual representation of ascent
speed (i.e., an ascent speedometer).
The segments of the ASC represent two sets of speeds which
change at a reference Depth of 60 FT (18 M). Refer to the chart
for segment values.
WARNING: At depths greater than 60 FT (18 M),
ascent rates should not exceed 60 feet per
minute (18 meters per minute). At depths of 60
FT (18 M) and shallower, ascent rates should not
exceed 30 feet per minute (9 meters per
minute).

ALPHA/NUMERIC DISPLAYS
Each numeric and graphic display represents a
unique piece of information. It is imperative that you
understand the formats, ranges, and values of the
information represented to avoid any possible mis-
understanding that could result in error.
Depth
Current Depth is displayed on the Main Dive screens (Fig. 8a)
with the FT (or M) icon from 0 to 330 FT (99.9 M) in NORM/
FREE, 399 FT (120 M) in GAUG, in increments of 1 FT (.1 M).
Stop Depths (Deep, Safety, and Deco) are also displayed on the
Main screens (Fig. 8b) when applicable.
Max Depth is displayed on Alternate screens (Fig. 9a) with the
MAX and FT (or M) icons from 0 to 330 FT (99.9 M) in NORM/
FREE, 399 FT (120 M) in GAUG, in increments of 1 FT (.1 M).
Time and Date
Most Time displays like Time of Day (Fig. 9b) are shown in
hour:minute format (i.e., 9:46 represents 9 hours and 46 min-
utes, not 946 minutes!). The colon that separates hr:min
(min;sec) blinks once per second when the display is indicating
real time (e.g., Time of Day, Elapsed Dive Time).

When Times are calculated projections such as NDC and
Elapsed Dive Time (Fig. 10a/b), the colon is solid (non blinking).
FREE Dive Mode displays Times in minute:second format.
Date is only displayed in Log Mode.
Temperature
Temperature can be viewed by accessing an Alternate Display
while on the surface and during dives (Fig. 11a).
Altitude
When above the sea level range, which extends up to 3,000
feet (915 meters) elevation, Altitude can be viewed on Surface
Alternate screens as EL (Elevation Level) from 2 up to 7 (Fig.
11b).
EL2 = 3,001 to 5,000 feet (916 to 1,525 meters)
EL3 = 5,001 to 7,000 feet (1,526 to 2,135 meters)
EL4 = 7,001 to 9,000 feet (2,136 to 2,745 meters)
EL5 = 9,001 to 11,000 feet (2,746 to 3,355 meters)
EL6 = 11,001 to 13,000 feet (3,356 to 3,965 meters)
EL7 = 13,001 to 14,000 feet (3,966 to 4,270 meters)

• It should not be considered that the capabilities built into the Element II provide
an implied approval or consent from TUSA for individuals to exceed the defined
limits for recreational diving, as agreed on by all internationally recognized
training agencies.
• The oxygen features of the Element II are intended for use by recreational divers
trained for Nitrox diving by an instructor certified by a recognized training
agency to teach diving with Nitrox.
• Conducting repetitive dives using enriched nitrogen-oxygen mixtures can lead
to oxygen buildup, reducing oxygen tolerance while increasing the risk of
pulmonary oxygen toxicity.
• The Element II provides information based upon a personal dive profile, and
therefore must not be shared between divers. It is impossible for two divers to
stay precisely together underwater, and your computer's dive profile tracking
of previous dives will be pertinent to you only. Nitrogen and oxygen loading of
a second user may be significantly different and swapping dive computers
could lead to inaccurate and dangerous predictions of decompression and
oxygen accumulation status.
WARNINGS AND SAFETY RECOMMENDATIONS

SETTING FO2 FOR NITROX DIVES
• For each value of FO2, the MOD (Max Operating Depth) that can be achieved for
the PO2 Alarm limit previously set will be displayed.
• When the FO2 50% Default is set On and FO2 Gas 1 is set for a numerical value, 10
minutes on the surface after that dive, the FO2 for Gas 1 will be displayed as 50 and
further dives will be calculated based on 50% O2 for oxygen calculations and 21%
O2 for Nitrogen calculations (79% Nitrogen) unless the FO2 for Gas 1 is set before
the dive.
• FO2 for Gas 1 continues to reset to the FO2 50% Default after subsequent repetitive
dives until 24 hours elapse after the last dive, or the FO2 50% Default is turned Off.
• When the FO2 50% Default is set Off, the FO2 for Gas 1 will remain at the last Set
Point for the remainder of that series of repetitive dives.
• The default FO2 for Gas 1 each new dive period is Air.
• When FO2 for Gas 1 is set for AIR, the calculations are the same as when it is set to
an FO2 of 21%. When FO2 for Gas 1 is set to Air, it remains set for Air until it is set
for a numerical FO2 value (21 to 50%).
• When FO2 is set only to Air, the O2BG and PO2 values and/or warnings will not be
displayed during the dive.
• MODs affected by the PO2 limit set will not be displayed when FO2 for Gas 1 is set
to Air.
• The Element II keeps track of O2 so that if FO2 for Gas 1 is subsequently set for a
numerical value, the O2 accumulated during previous Air dives will be accounted for
in the next Nitrox dive (during that dive period and series of repetitive dives).
• Once FO2 Gas 1 is set for a numerical value (21 to 50%) and a dive is made, the
Air option is disabled until 24 hours elapse after the last dive. The Air option will not
be displayed in Set FO2 Gas 1 until a full 24 hour Surface Interval has elapsed.

M
A
S
• If FO2 for Gas 1 is set for 21%, it will remain set for 21% for that series of dives until
set for a higher numerical value.
• If the FO2 50% Default is set Off, FO2 for Gas 2 will remain at it's Set Point

NORM PLAN MODE
TUSA strongly recommends that you review the Plan Mode dive times
prior to every NORM dive to help you plan your dive as required to avoid
exceeding no decompression or oxygen exposure limits. This is especially
important for repetitive dives when Plan Mode indicates adjusted dive times that are
available for the next dive, based on residual nitrogen or oxygen accumulation (whichever
is in control) following the last dive and surface interval.
NOTE: No Decompression Dive Times in Plan Mode are based on the
FO2 setting for Gas 1. The FO2 setting for Gas 2 is not utilized for
Plan calculations.
Plan Mode can only be accessed while viewing NORM SURF MAIN.

WARNINGS:
Making decompression dives without the proper preparation and
training will place you in an unnecessarily dangerous situation.
Existing data for making planned decompression dives is limited,
and virtually non-existent for repetitive decompression diving.
Decompression diving greatly increases your risk of decompression
sickness.
Special training, equipment, and support are necessary for diving
deeper than the maximum recommended sport diving depth
limit(s).

NORM DIVE MODES

NO DECO DIVE TIME REMAINING (NDC)
The Element II constantly monitors No Decompression status.
NDC is the maximum amount of time that you can stay at your
present Depth before entering a Decompression situation. It is
calculated based on the amount of Nitrogen absorbed by
hypothetical tissue compartments.
The rates each of these compartments absorb and release
Nitrogen is mathematically modeled and compared against a
maximum allowable Nitrogen level.
Whichever one is closest to this maximum level is the controlling
compartment for that Depth. Its resulting value will be displayed
as NDC (Fig. 49a) and the NiBG (Fig. 49b).
As you ascend from Depth during a dive, the NiBG segments
will recede as control shifts to slower compartments.
This is a feature of the Decompression model that is the basis for
multilevel diving, one of the most important advantages that the
Element II dive computer offers.

OXYGEN ACCUMULATION
If FO2 was set for a numerical value (Nitrox), the O2BG (Fig.
50a) will add segments to represent oxygen accumulation for
that dive, or 24 hour period, whichever amount is greater.
If O2 reaches 100% of the allowed limit (300 OTU), the graphic
O2 will replace NDC. High O2 is described later.
ASCENT RATE INDICATOR (ASC)
The ASC shows how fast you are ascending. When you exceed
the maximum recommended Ascent Rate for the depth you are at
(see chart on page 17), all segments of the ASC will flash (Fig.
51) and the graphic SLO will flash (Fig. 51a), replacing NDC
time (or GAU graphic). The flashing will stop and NDC time (or
GAU graphic) restored when the audible is silenced or your
Ascent Rate is slowed below the alarm value.
The Ascent Rate alarm is based upon 2 sets of speeds which
change at a reference depth of 60 FT (18 M).
WARNING: At depths greater than 60 FT (18 M),
Ascent Rates should not exceed 60 FPM (18
MPM). At depths of 60 FT (18 M) and shallower,
Rates should not exceed 30 FPM (9 MPM).

No Deco Deep Stop
On any No Deco dive in which Depth exceeds 80 FT (24 M), a
Deep Stop Preview screen (Fig. 55) can be accessed that will
display the graphic DS (meaning Deep Stop) and a recom-
mended Stop Depth calculated to be 1/2 the Max Depth and a
Stop Time of 02:00 (2 minutes) with DS and STOP icons. It will
revert to the Main after 5 seconds.
• The intent of this screen is to suggest that a Stop should be
made as indicated to help reduce tissue nitrogen loading
prior to final ascent.
• The Preview screen will not be available for viewing once
you ascend above the Stop Depth.
NOTE: The Deep Stop is not required and al-
though recommended, it does not have to be
taken. There is no penalty if the Stop is ignored
and ascent (or other activity) is continued.
Upon ascending to within 10 FT (3 M) below the calculated Stop
Depth, the DS Main screen (Fig. 56) will appear displaying the
calculated Stop Depth with FT (or M), DS, and STOP icons and
the Timer that counts down from 02:00 to 0:00 (min:sec) with
clock icon. Also displayed will be NDC (hr:min) with wave/
clock/profile mode icon, Tank icon (Gas 1 or 2), current Depth
with FT (or M) icon, and applicable bar graphs.

are coming to the limits of oxygen exposure.
If the theoretical amount of oxygen accumulated reaches the limit
for a single exposure, or 24 hour period (300 OTU = 100%),
the graphic O2 replaces NDC time and the full O2BG and Up
Arrow icon will be displayed flashing (Fig. 69).

• The percentage of oxygen (FO2) in the Nitrox mix being used must be 'set
before each nitrox dive', unless the FO2 50% Default feature is set OFF (a user
setting).
• Plan Mode provides predicted times for subsequent dives. Depending on
cylinder size, breathing gas consumption, and oxygen accumulation, you may
have less time available than indicated because of breathing gas quantity or
other limitations.
• Until it has shut itself off, you must not use the Element II at a different Altitude
than the Altitude at which it was activated. Doing so will result in an error
equal to the difference in barometric pressure, and possibly a false dive mode
with erroneous data.
• To provide proper Altitude compensation, the Element II must be manually
activated at the new altitude. Dive computers, such as the Element II cannot
sense changes in barometric pressure if activated by immersion in water at
higher Altitudes.
• Use the Caution Zone of the Nitrogen Bar Graph as a visual reference to provide
a greater margin of protection between you and the No Decompression Limits.
• Every effort should be made to keep each of the Bar Graphs in the normal zone
throughout your dives to reduce your risk of exposure to decompression
sickness, oxygen toxicity, and the effects of excessive ascent rates.

S
SWITCHING GAS MIXES (NORM only)
During NORM Dives, the FO2 calculations/displays can be switched from Gas 1 to 2.
> Switching Gas cannot be performed while on the surface.
> Every dive begins with Gas 1 and 10 minutes after surfacing from a multiple gas
dive, operation defaults to the Gas 1 FO2.
> Access to Gas Switching screens can only be accomplished during the time that a
NORM Dive Main screen is being displayed and cannot be performed during the
time that an Alarm is sounding.
NOTE: If a Switch to a new Gas mix would expose the diver to a
prohibitive PO2 level of 1.60 ATA or greater, the Audible Alarm will
sound and the graphics DO - NOt - CHNG GAS will flash on the dis-
play (Fig. 70) until the Audible is silenced.
Due to the possibility that sufficient air may not be available in
the Switch From tank to complete the dive, the Switch to the
prohibitive Mix is still allowed.
> If the Switch is made to the prohibitive Mix, the High PO2
Alarm will activate.
> If in Deco, the graphic PO2 will flash in place of TAT until
PO2 decreases below 1.60, then TAT will be restored.
Switching of Gas Mixes can only to be performed during the
time that a Gas Switch Preview screen is being displayed.

UPLOADING SETTINGS AND DOWNLOADING DATA
The Element II is configured with a Data Port located on the back of the left side that
enables it to be connected to a PC through a USB port using a special Interface Cable that
is available as an optional accessory.
The USB Driver required for the Interface system is downloadable from tusa.com.
The Settings Upload portion of the program provided can be used to set/change the Set A
group (Alarms), Set U group (Utilities), and Set T group (Time/Date) using the same Inter-
face System. The Set F group (FO2) and FREE Mode Alarms must be entered using the
Element II's button controls.
Information available for retrieval (DownLoad) from the Element II to the PC Download
portion of the program includes dive number, surface interval time, maximum depth,
elapsed dive time, start date, start time, lowest temperature underwater, sampling rate,
dive profile, Set Points, NiBG, O2BG, and Gas Switching events.
The Element II checks for the presence of an interface device connection to the Data Port
once every second while in Surface mode. Checks are not made if the Wet Activation
contacts are wet. Upon sensing an interface connection, the requesting device (PC)
connects to the Element II and is prepared for Upload of settings or Download of data
which are then initiated using the PC program.
Prior to attempting to Download data from your Element II or Upload Settings to it, review
the HELP section of the interface program. Recommended is to print those sections of HELP
that you consider appropriate for your Interface activities.

Although breathing apparatus is not utilized for Free Dive activities, nitrogen tissue loading remains a
factor. Nitrogen loading is calculated based upon a fixed FO2 of AIR. Since a user has the option of
alternating between NORM (SCUBA) and Free Dive activities within a 24 hour period, nitrogen
calculations and the displayed value of NDC Time are carried over from one operating mode to the
other, which permits the user to maintain awareness of nitrogen absorption and off gassing status.
The mathematical model currently used in the Element II is based on no decompression/decompression
multilevel repetitive dive schedules. This algorithm does not take into account the physiological
changes associated with the high pressures that competitive type Free diving can expose a diver to.
WARNINGS:
• Ensure that you know which Operating Mode is selected (NORM, GAUG, or
FREE) prior to commencing any dive.
• Conducting Free dives within a 24 hour period after conducting SCUBA dives,
combined with the effects of multiple rapid Free Dive ascents, increases your risk
of decompression sickness. Such activities may result in accelerated entry into
decompression which could cause serious injury or death.
• Combining competitive type Free dive activities that involve multiple descents/
ascents with activities utilizing SCUBA during the same 24 hour period is not
recommended. Presently, there is no data relating to such activities.
• It is highly recommended that anyone planning to become involved in
competitive type Free Dive activities obtain proper instruction and training from
a recognized Free Diving trainer. It is imperative that the physiological affects
be understood and the diver is physically prepared.
ADDITIONAL INFORMATION PERTAINING TO FREE DIVE MODE

RESPONSIBLE COMPUTER DIVING
• Plan each dive, and dive your plan. The Element II was not designed to
make decisions for you, only to provide you with the information you need
to make responsible decisions for yourself. This begins with a dive Plan
that will help you avoid a low air or decompression situation.
• Do not plan any dive that exceeds your training or experience level.
• Inspect your Element II before every dive. If it shows any signs of damage
or abnormal function, DO NOT dive with it until it has received factory
prescribed service.
• Make a Safety Stop at 15 to 20 FT (4.5 to 6 M) at the end of every dive. It's
important, don't forget it.
• You should make every effort to complete all of your ascents with the
Nitrogen Bar Graph inside the normal No Decompression zone.
• If you inadvertently entered Decompression, you should not complete your
ascent until the Nitrogen Bar Graph is at least inside the No Decompres-
sion Caution Zone.
• While you cannot provide a guarantee against the occurrence of decom-
pression sickness, you may choose your own personal zone of caution
based upon your individual age, physique, excessive weight, training,
experience, etc. to reduce the statistical risk. By not pushing the limits,
you can establish and adjust your personal level of conservatism and
margin of safety.

GENERAL
100
CARE AND CLEANING
Protect your Element II from shock, excessive temperatures,
chemical attack, and tampering. Protect the lens against
scratches with a transparent Instrument Lens Protector. Small
scratches will naturally disappear underwater.
• Soak and rinse the Element II in fresh water at the end of
each day of diving, and check to ensure that the areas
around the low pressure (depth) sensor (Fig. 100a) and
button are free of debris or obstructions.
• To dissolve salt crystals, use lukewarm water or a 50%
white vinegar/50% fresh water bath. After removal from
the bath, place the unit under gently running water and
towel dry before storing.
• Transport your unit cool, dry, and protected.
INSPECTIONS AND SERVICE
Your Element II should be inspected annually by an Authorized
TUSA Dealer who will perform a factory prescribed function
check and inspection for damage or wear. To keep the
product's warranty in effect, this inspection must be completed
one year after purchase (+/- 30 days). TUSA recommends that
you continue to have this inspection performed every year to
ensure it is working properly.
To Obtain Service
Take your Element II to an Authorized TUSA Dealer.

age due to improper battery replacement is not covered by the unit's
warranty.
When the battery is removed, settings and calculations for repetitive
dives will be retained in non volatile memory for subsequent opera-
tions.
MODULE REMOVAL FROM BOOT
If the Module is in a Console, bend the rubber Console Boot back to expose the edge of
the Module. If the Boot is flexible enough to permit, you may bend it back far enough to
scoop the Module out with your finger. Otherwise, it may be necessary to insert a blunt
screwdriver until the tip rests just underneath the Module. DO NOT pry the Module from
the Console! Slowly increase the pressure under the Module by releasing the tension on
the rubber Boot. The Module will slide up the screwdriver and exit the Console.
If the Module is in a Wrist Boot, it will be necessary to peel the lips of the Boot downward
off the Module while applying pressure from underneath, working it out slowly.
BATTERY REPLACEMENT
The Battery Compartment should only be opened in a dry and clean environment with
extreme care taken to prevent the entrance of moisture or dust. To prevent formation of
moisture in the Battery Compartment, it is recommended that the Battery be changed in an
environment equivalent to the local outdoor temperature and humidity (e.g., do not change
the Battery in an air conditioned environment, then take it outside during a hot sunny day).
102

ALTITUDE SENSING AND ADJUSTMENT
Prior to the first dive of a series of repetitive dives, Altitude (i.e., Ambient Pressure) is
measured upon activation and every 15 minutes until a dive is made.
> While it is operating in Surface mode after a dive, measurements are taken every 15
minutes during the 24 hour period after surfacing.
> Measurements are only taken when the unit is dry.
> Two readings are taken, the second reading 5 seconds after the first. The readings
must be within 1 foot (30 cm) of each other to record that ambient pressure as the
current Altitude.
The mathematical model in the Element II accounts for the reduced No Deco Dive Times
available based on National Oceanic and Atmospheric Administration (NOAA) guide-
lines.
When diving in high altitude waters from 3,001 to 14,000 feet (916 to 4,270 meters), the
Element II automatically adjusts to these conditions providing corrected Depth, reduced No
Deco Dive Times, and reduced Oxygen Accumulation Times at Altitude intervals of 1,000
feet (305 meters).
No adjustments are made during any time that the Wet Contacts are wet.
At an elevation of 3,001 feet (916 meters), Depth Calibration automatically changes from
feet of seawater to feet of fresh water. This is the first adjustment to the Algorithm.
107
When the Conservative Factor feature is set ON, allowable dive times are calculated
based upon the next higher 3,000 foot (915 meter) Altitude. All adjustments for Altitudes
greater than 11,000 feet (3,355 meters) are then made to allowable dive times for
14,000 feet (4,270 meters). If the Conservative Factor is set ON while at Sea Level,
calculations are based upon NDLs listed in the tables for the 5,001 to 6,000 foot (1,526
to 1,830 meter) range.
The Element II will not function as a Dive Computer above 14,000 feet (4,270 meters).
