1 GENERAL INFORMATION
1.1 INTRODUCTION
The STANDARD HORIZON MATRIX Series GX2000 and GX2100 Marine VHF/
FM Marine transceiver are designed to be used in USA, International and Ca-
nadian Marine bands. The GX2000 and GX2100 can be operated from 11 to
16 VDC and has a switchable RF output power of 1 watt or 25 watts.
MATRIX AIS GX2100
Integrates a dual channel AIS (Automatic Identification System) receiver to
display AIS vessel information (MMSI, Call Sign, Ship Name, BRG, DST, SOG
and COG) directly on the VHF radio, so you will know what is out there in any
conditions. The GX2100 is also capable of entering and saving up to 100
waypoints, which may be selected and navigated to by using a unique naviga-
tion compass display. The MATRIX AIS allows you to contact an AIS Ship
directly using DSC, show your vessels position in relation to AIS targets and
alert you when an AIS ship may be approaching too close to your location via
the Closest Point of Approach (CPA) Alarm. To receive AIS targets from ships
with AIS class A or B transponders, simply connect the normal VHF antenna
(only one antenna needed!)
MATRIX - GX2000
For the mariner who already has AIS on-board and desires a VHF with the
features of the MATRIX AIS, the MATRIX GX2000 has a connection for an AIS
receiver or transponder.
The MATRIX Series VHF’s are capable of DSC (Digital Selective Calling) Class
D operation. Class D operation allows continuous receiving of Digital Selective
Calling functions on channel 70 even if the radio is receiving a call. The MA-
TRIX Series VHF's operate on all currently-allocated marine channels which
are switchable for use with USA, International, or Canadian regulations. Emer-
gency channel 16 can be immediately selected from any channel by pressing
the red
[
16/9
]
key. NOAA Weather channels can also be accessed immedi-
ately by pressing and holding the
[
CLR
(
WX
)]
key.
Other features of the MATRIX Series VHF’s include: Speaker Microphone,
30W PA/Fog, optional RAM3 second station remote-control microphone with
display, intercom between radio and optional RAM3, scanning, priority scan-
ning, submersible speaker mic, high and low voltage warning, and GPS re-
peatability.

4 SAFETY / WARNING INFORMATION
This radio is restricted to occupational use, work related operations only where
the radio operator must have the knowledge to control the exposure condi-
tions of its passengers and bystanders by maintaining the minimum separa-
tion distance of 0.89 m (2.92 feet). Failure to observe these restrictions will
result in exceeding the FCC RF exposure limits.
Antenna Installation:
The antenna must be located at least 0.89 m (about 3 feet) away from passen-
gers in order to comply with the FCC RF exposure requirements.

5 FCC RADIO LICENSE INFORMATION
Standard Horizon radios comply with the Federal Communication Commis-
sion (FCC) requirements that regulate the Maritime Radio Service.
5.1 STATION LICENSE
An FCC ship station license is no longer required for any vessel traveling in
U.S. waters (except Hawaii) which is under 20 meters in length. However, any
vessel required to carry a marine radio on an international voyage, carrying a
HF single side band radiotelephone or marine satellite terminal is required to
have a ship station license. FCC license forms, including applications for ship
(605) and land station licenses can be downloaded via the Internet at http://
www.fcc.gov/Forms/Form605/605.html. To obtain a form from the FCC, call
(888) 225-5322.
5.2 RADIO CALL SIGN
Currently the FCC does not require recreational boaters to have a Ship Radio
Station License. The USCG recommends the boats registration number and
the state to be used when calling another vessel.
5.3 CANADIAN SHIP STATION LICENSING
You may need a license when traveling in Canada. If you do need a license
contact their nearest field office or regional office or write:
Industry Canada

6 FCC NOTICE
NOTICE
Unauthorized changes or modifications to this equipment may void com-
pliance with FCC Rules. Any change or modification must be approved
in writing by STANDARD HORIZON.
NOTICE
This equipment has been tested and found to comply with the limits for
a Class B digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions, may cause harmful interference to ra-
dio communications. However, there is no guarantee that interference
will not occur in a particular installation. If this equipment does cause
harmful interference to radio or television reception, which can be de-
termined by turning the equipment off and on, the user is encouraged to
try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
NOTE
The MATRIX AIS GX2100 does not require a special marine VHF an-
tenna to receive AIS transmissions. The MATRIX AIS does not transmit
AIS signals, it is NOT recommended to use an antenna dedicated for
AIS operation.
What is the range for AIS receivers?
Since AIS uses similar frequencies as a marine VHF radio, it has similar radio
reception capabilities - which are basically line of sight. This means that the
higher the VHF antenna is mounted, the greater the reception area will be.
Reception from Class A vessels that are 20 or even 30 miles away on open
water is not uncommon as their antennas are mounted high off the water.
Class B transponders use lower power for transmissions; therefore you can
expect Class B vessels to be acquired when they are 5 to 10 miles away.
Page 13GX2000/GX2100
7 GETTING STARTED
7.1 PROHIBITED COMMUNICATIONS
The FCC prohibits the following communications:
False distress or emergency messages:
Messages to “any boat” except in emergencies and radio tests;
Messages to or from a vessel on land;
Transmission while on land;
Obscene, indecent, or profane language (potential fine of $10,000).
7.2 ABOUT VHF RADIO
The radio frequencies used in the VHF marine band lie between 156 and 158
MHz with some shore stations available between 161 and 163 MHz. The ma-
rine VHF band provides communications over distances that are essentially
“line of sight” (VHF signals do not travel well through objects such as buildings,
hills or trees). Actual transmission range depends much more on antenna type,
gain and height than on the power output of the transmitter. On a fixed mount
25W radio transmission expected distances can be greater than 15 miles, for
a portable 5W radio transmission the expected distance can be greater than 5
miles in “line of sight”.
7.3 SELECTING AN ANTENNA
Marine antennas are made to radiate signals equally in all horizontal direc-
tions, but not straight up. The objective of a marine antenna is to enhance the
signal toward the horizon. The degree to which this is accomplished is called
the antenna’s gain. It is measured in decibels (dB) and is one of the major
factors in choosing an antenna. In terms of effective radiated power (ERP),
antennas are rated on the basis of how much gain they have over a theoretical
antenna with zero gain. A 3 foot, 3dB gain antenna represents twice as much
gain over the imaginary antenna.
Typically a 3 foot 3dB gain stainless steel whip is used on a sailboat mast. The
longer 8 foot 6dB fiberglass whip is primarily used on power boats that require
the additional gain.
GX2000/GX2100Page 14
7.4 COAXIAL CABLE
VHF antennas are connected to the transceiver by means of a coaxial cable –
a shielded transmission line. Coaxial cable is specified by it’s diameter and
construction.
For runs less than 20 feet, RG-58/U, about 1/4 inch in diameter is a good
choice. For runs over 20 feet but less than 50 feet, the larger RG-8X or RG-
213/U should be used for cable runs over 50 feet RG-8X should be used. For
installation of the connector onto the coaxial cable refer to the figure below.
To get your coax cable through a fitting and into your boat’s interior, you
may have to cut off the end plug and reattach it later. You can do this if
you follow the directions that come with the connector. Be sure to make
good soldered connections.

7.5 EMERGENCY
(
CHANNEL 16 USE
)
Channel 16 is known as the Hail and Distress Channel. An emergency may be
defined as a threat to life or property. In such instances, be sure the transceiver
is on and set to CHANNEL 16. Then use the following procedure:
1. Press the microphone push-to-talk switch and say “Mayday, Mayday, May-
day. This is , , ” (your vessel’s name).
2. Then repeat once: “Mayday, ” (your vessel’s name).
3. Now report your position in latitude/longitude, or by giving a true or mag-
netic bearing (state which) to a well-known landmark such as a navigation
aid or geographic feature such as an island or harbor entry.
4. Explain the nature of your distress (sinking, collision, aground, fire, heart
attack, life-threatening injury, etc.).
5. State the kind of assistance your desire (pumps, medical aid, etc.).
6. Report the number of persons aboard and condition of any injured.
7. Estimate the present seaworthiness and condition of your vessel.
8. Give your vessel’s description: length, design (power or sail), color and
other distinguishing marks. The total transmission should not exceed 1
minute.
9. End the message by saying “OVER”. Release the microphone button and
listen.
10. If there is no answer, repeat the above procedure. If there is still no re-
sponse, try another channel.
NOTE
The GX2000 and GX2100 have DSC Distress calling, that can transmit
a distress call digitally to all ships with compatible DSC radios. Refer to
section “11 DIGITAL SELECTIVE CALLING”.
GX2000/GX2100Page 16
7.6 CALLING ANOTHER VESSEL
(
CHANNEL 16 OR 9
)
Channel 16 may be used for initial contact (hailing) with another vessel.
However, its most important use is for emergency messages. This channel
must be monitored at all times except when actually using another channel.
It is monitored by the U.S. and Canadian Coast Guards and by other vessels.
Use of channel 16 for hailing must be limited to initial contact only. Call-
ing should not exceed 30 seconds, but may be repeated 3 times at 2-minute
intervals. In areas of heavy radio traffic, congestion on channel 16 resulting
from its use as a hailing channel can be reduced significantly in U.S. waters by
using channel 9 as the initial contact (hailing) channel for non-emergency
communications. Here, also, calling time should not exceed 30 seconds but
may be repeated 3 times at 2-minute intervals.
Prior to making contact with another vessel, refer to the channel charts in this
manual, and select an appropriate channel for communications after initial
contact. For example, Channels 68 and 69 of the U.S. VHF Charts are some of
the channels available to non-commercial (recreational) boaters. Monitor your
desired channel in advance to make sure you will not be interrupting other
traffic, and then go back to either channel 16 or 9 for your initial contact.
When the hailing channel (16 or 9) is clear, press the PTT button on the mic
and state the name of the other vessel you wish to call and then “this is
followed by the name of your vessel and your Station License (Call Sign) then
release the PTT button on the mic. When the other vessel returns your call,
immediately request another channel by pressing the PTT button on the mic
and saying “go to,” the number of the other channel, say “over” and release
the PTT button on the mic. Then switch to the new channel. When the new
channel is not busy, call the other vessel.
After a transmission, say “over,” and release the microphone’s push-to-talk
(PTT) switch. When all communication with the other vessel is completed, end
the last transmission by stating your Call Sign and the word “out.” Note that it
is not necessary to state your Call Sign with each transmission, only at the
beginning and end of the contact.
Remember to return to Channel 16 when not using another channel. Some
radios automatically monitor Channel 16 even when set to other channels or
when scanning.
Page 17GX2000/GX2100
7.7 MAKING TELEPHONE CALLS
To make a radiotelephone call, use a channel designated for this purpose, The
fastest way to learn which channels are used for radiotelephone traffic is to
ask at a local marina. Channels available for such traffic are designated Pub-
lic Correspondence channels on the channel charts in this manual. Some
examples for USA use are Channels 24, 25, 26, 27, 28, 84, 85, 86, and 87.
Call the marine operator and identify yourself by your vessel’s name, The marine
operator will then ask you how you will pay for the call (telephone credit card,
collect, etc.) and then link your radio transmission to the telephone lines.
The marine telephone company managing the VHF channel you are using
may charge a link-up fee in addition to the cost of the call.
7.8 OPERATING ON CHANNELS 13 AND 67
Channel 13 is used at docks and bridges and by vessels maneuvering in port.
Messages on this channel must concern navigation only, such as meeting and
passing in restricted waters.
Channel 67 is used for navigational traffic between vessels.
By regulation, power is normally limited to 1 Watt on these channels. Your
radio is programmed to automatically reduce power to this limit on these chan-
nels. However, in certain situations it may be necessary to temporarily use a
higher power. See page 30 (
[
H/L
]
key) for means to temporarily override the
low-power limit on these two channels.
GX2000/GX2100Page 18
8 INSTALLATION
8.1 LOCATION
The radio can be mounted at any angle. Choose a mounting location that:
is far enough from any compass to avoid any deviation in compass read-
ing due to the speaker magnet
provides accessibility to the front panel controls
allows connection to a power source and an antenna
has nearby space for installation of a microphone hanger
choose a mounting location that is at least 3 feet (1 m) away from the
radio’s antenna.
Note: To insure the radio does not affect the compass or radios performance is
not affected by the antenna location, temporarily connect the radio in the de-
sired location and:
a. Examine the compass to see if the radio causes any deviation
b. Connect the antenna and key the radio. Check to ensure the radio is
operating correctly by requesting a radio check.
8.2 MOUNTING THE RADIO

11 DIGITAL SELECTIVE CALLING
11.1 GENERAL
WARNING
This radio is designed to generate a digital maritime distress and safety
call to facilitate search and rescue. To be effective as a safety device,
this equipment must be used only within communication range of a shore-
based VHF marine channel 70 distress and safety watch system. The
range of signal may vary but under normal conditions should be ap-
proximately 20 nautical miles.
NOTE
A DSC Warning sticker is included with the
GX2000/GX2100. To comply with FCC
regulations this sticker must be mounted
in a location that can be easily viewed from
the location of the GX2000/GX2100.
Digital Selective Calling is a semi-automated method of establishing a radio
call, it has been designated by the International Maritime Organization (IMO)
as an international standard for establishing VHF, MF and HF radio calls. It has
also been designated as part of the Global Maritime Distress and Safety Sys-
tem (GMDSS).
Digital Selective Calling allows mariners to instantly send a distress call with GPS
position (when connected to the transceiver) to the US Coast Guard and other ves-
sels within range of the transmission. DSC will also allow mariners to initiate or re-
ceive Distress, Urgency, Safety, Routine, Position Request, Position Report, Auto-
matic Position Polling and Group calls to or from another vessel equipped with a
DSC transceiver.
11.2 MARITIME MOBILE SERVICE IDENTITY
(
MMSI

11.7 GROUP CALL
This feature allows the user to contact a group of specific vessels (example
members of a yacht club) using DSC radios with Group call function to auto-
matically switch to a desired channel for voice communications. This function
is very useful for yacht clubs and vessels traveling together that want to collec-
tively make announcements on a predetermined channel. Up to 32 Group
MMSI may be programmed.
11.7.1 Setup a Group Call
For this function to operate, the same Group MMSI must be programmed into
all the DSC VHF radios within the group of vessels that will be using this fea-
ture. To understand Group MMSI programming, first a Ship MMSI has to be
understood.
Ship MMSI: The first three digits called a MID (Mobile Identity Group) of a Ship
MMSI denote the country the ship registered for a MMSI. The last 6 digits are
specific to the Ships ID.
Ship MMSI Example: If your MMSI is “366123456”, “366” is MID which denote
the country and “123456” is your ships MMSI.
Group MMSI:
Group MMSI numbers are not assigned by the FCC or other organizations
licensed to assign ship MMSI numbers.
The first digit of a Group MMSI is always set to “0” by International rules.
All Standard Horizon radios are preset so when programming a Group
MMSI the first digit is set to “0”.
The USCG recommends programming the MID of a ships MMSI into the
Second, Third and Fourth digits of the Group MMSI as it denotes the area
the ship is located in.
The last 5 digits are decided upon by persons in the Group. This is an
important step as all radios in the Group must contain the same Group
MMSI so they can be contacted by each other. There is a chance that
another group of vessels may program in the same Group MMSI. If this
happens, simply change one or more of the last 5 digits of the Group MMSI.

14.5 GROUP DIRECTORY
For this function to operate, the same Group MMSI must be programmed into
all the DSC VHF radios within the group of vessels that will be using this fea-
ture. To understand Group MMSI programming, first a Ship MMSI has to be
understood.
Ship MMSI: The first three digits called a MID (Mobile Identity Group) of a Ship
MMSI denote the country the ship registered for a MMSI. The last 6 digits are
specific to the Ships ID.
Ship MMSI Example: If your MMSI is “366123456”, “366” is MID which denote
the country and “123456” is your ships MMSI.
Group MMSI:
Group MMSI numbers are not assigned by the FCC or other organizations
licensed to assign ship MMSI numbers.
The first digit of a Group MMSI is always set to “0” by International rules.
All Standard Horizon radios are preset so when programming a Group
MMSI the first digit is set to “0”.
The USCG recommends programming the MID of a ships MMSI into the
Second, Third and Fourth digits of the Group MMSI as it denotes the area
the ship is located in.
The last 5 digits are decided upon by persons in the Group. This is an
important step as all radios in the Group must contain the same Group
MMSI so they can be contacted by each other. There is a chance that
Page 99GX2000/GX2100
another group of vessels may program in the same Group MMSI. If this
happens, simply change one or more of the last 5 digits of the Group MMSI.

15 AIS/COMPASS SETUP
15.1 AUTOMATIC IDENTIFICATION SYSTEM
(
AIS
)
NOTE
The MATRIX AIS GX2100 does not require a special marine VHF an-
tenna to receive AIS transmissions. The MATRIX AIS GX2100 does not
transmit AIS signals, it is NOT recommended to use an antenna dedi-
cated for AIS operation.
The Automatic Identification System (AIS) is a short range coastal tracking
system. AIS is intended to assist in collision avoidance by seeing positions
and courses of AIS equipped vessels around your vessel.
AIS is mandatory on passenger ships, irrespective of size, all ships 300 gross
tonnage and larger engaged on international voyages, cargo ships of 500 gross
tonnage and larger not engaged on international voyages.
AIS uses two marine VHF channels. Each ship equipped with an AIS tran-
sponder transmits a packet every few seconds with information about the ship
and its voyage. Radio frequencies: AIS1 = 161.975 MHz, or channel 87B and
AIS2 162.025 MHz , or channel 88B. A stand-alone AIS receiver or the AIS
receiver built in to a Class A or Class B transponder can pick up these radio
signals and translate them into a NMEA data sentence that can be understood
by a computer with the proper software or by an AIS-enabled chart plotter.
Classes of AIS:
Class A - 12.5W power output - mandated for use on SOLAS Chapter V ves-
sels (and others in some countries).
Class B -2W output - lower cost derivative for leisure and non-SOLAS markets.
The MATRIX AIS GX2100 is capable of receiving Class A and B transmission
with the internal Dual Channel AIS receiver. The GX2000 must be connected
to an optional AIS receiver or transponder.
What is the range for AIS receivers?
Since AIS uses similar VHF frequencies as a marine VHF radio, it has
similar radio reception capabilities - which are basically line of sight. This
means the higher your VHF antenna is mounted, the greater the reception
area will be.
Reception from Class A vessels that are 20 or even 30 miles away on open
water is not uncommon as their antennas are mounted high off the water.
Class B transponders use lower power for transmissions, therefore you can
expect Class B vessels to be received when they are 5 to 10 miles away.
For additional information on AIS visit the USCG web site: <http://
www.navcen.uscg.gov/marcomms/ais.htm>

18 MAINTENANCE
The inherent quality of the solid-state components used in this transceiver will
provide many years of continuous use. Taking the following precautions will
prevent damage to the transceiver.
Keep the microphone connected or the jack covered at all times to prevent
corrosion of electrical contacts;
Never key the microphone unless an antenna or suitable dummy load is
connected to the transceiver.
Ensure that the supply voltage to the transceiver does not exceed 16 VDC
or fall below 11 VDC.
Use only STANDARD HORIZON-approved accessories and replacement
parts.
In the unlikely event of serious problems, please contact your Dealer or our
repair facility. Address and phone numbers for this facility, as well as warranty

SYMPTOM
Transceiver fails to
power up.
Transceiver blows fuse
when connected to
power supply.
Popping or whining
noise from the speaker
while engine runs.
Sound is not emitted
from the internal or ex-
ternal speaker.
Sound is not emitted
from the PA speaker.
Receiving station re-
ports low transmit
power, even with trans-
ceiver set to HI power.
“HI BATTERY” or “LO
BATTERY” message
appears when the
power is turned on.
“AIS” information is not
displayed (GX2000).
Your position is not dis-
played.
PROBABLE CAUSE
No DC voltage to the
transceiver, or blown
fuse.
Reversed power
wires.
Engine noise.
Accessory cable.
Accessory cable.
Antenna.
The power supply
voltage is too high or
too low.
Accessory cable.
Accessory cable.
Setting of the GPS
navigation receiver.
REMEDY
a. Check the 12VDC battery connections and
the fuse.
b. The VOL/PWR knob needs to be pressed and
held to turn the radio on.
Check the power cable for DC voltage, or re-
place the fuse (6A 250V).
Make sure the red wire is connected to the posi-
tive (+) battery post, and the black wire is con-
nected to the negative (-) battery post. If the fuse
still blows, contact your Dealer.
Reroute the DC power cables away from the
engine. Add noise suppressor on power cable.
Change to resistive spark plug wires and/or add
an alternator whine filter.
Check the connections of the accessory cable
(Short Circuit the External speaker cable
WHITE/SHIELD).
Check the accessory cable connection (Short
Circuit the PA speaker cable RED/SHIELD).
Have the antenna checked or test the trans-
ceiver with another antenna. If the problem per-
sists, contact your Dealer for servicing.
Confirm that the connected power supply volt-
age is not 17 volts or lower than 10 volts.
Check the accessory cable connection (Short
Circuit the NMEA-HS(+) cable BROWN and
NMEA-COMMON (–) cable GREEN). Check the
baud rate setting of the AIS receiver is 38400
baud.
Check the accessory cable connection.
Some GPS use the battery ground line for NMEA
connection.
Check the output signal format of the GPS navi-
gation receiver. This radio requires NMEA0183
format with GLL, RMB, or RMC sentence as an
output signal. If the GPS has a baud rate set-
ting make sure to select 4800 and parity to
NONE.
An “RA” Return Authorization number is not necessary to send a product in for
service. Include a brief note describing the problem along with your name,
return address, phone number, and proof of purchase.
18.3 TROUBLESHOOTING CHART
GX2000/GX2100Page 120
19 CHANNEL ASSIGNMENTS
Tables on the following columns list the VHF Marine Channel assignments for
U.S.A. and International use. Below are listed some data about the charts.
1. VTS. Where indicated, these channels are part of the U.S. Coast Guard’s
Vessel Traffic System.
2. Alpha channel numbers, that is, channel numbers followed by the letter A
(such as Channel 07A) are simplex channels on the U.S.A. or Canadian
channel assignments whose counterparts in the International assignments
are duplex channels. International channels do not use “alpha” numbers.
If you call the Coast Guard on Channel 16, they will sometimes ask you to
go to channel 22 Alpha.” This is a channel assigned to U.S.A, and Cana-
dian Coast Guards for handling distress and other calls. If your radio is set
for International operation you will go to Channel 22 instead of 22A, and
will not be able to communicate with the Coast Guard. To use Channel
22A, your radio must be set for USA or Canada operation, usually by a U/
I/C (USA/International/Canada) control or combination of controls. Chan-
nel 22 (without an “A”) is an International duplex channel for port opera-
tions. Some radios indicate an “A” adjacent to the alpha channels on the
display; on others “alpha” is not indicated but the proper channel is se-
lected based on the U/I/C setting.
3. Bridge-to-Bridge channels (for example, Channel 13) are for use by bridge
operators on intercoastal waterways and rivers. It is also used by marine
vessels in the vicinity of these bridges for navigation and for communicat-
ing with the bridge operators. Note that a limit of 1 Watt is specified for
these channels. See page 17 for additional information.
4. The S/D column on the chart indicates either S (simplex) or D (duplex). Sim-
plex means transmitting and receiving on the same frequency. Only one party
at a time can talk, unlike a telephone. Be sure to say “over” and release your
microphone push-to-talk switch at the end of each transmission. Duplex op-
eration involves the use of one frequency for transmitting and a separate fre-
quency for receiving. On channels specified as duplex on the charts, correct
mode of operation is established automatically by your radio when you select a
channel; you cannot change the mode. And you still must release the push-to-
talk switch after each transmission in order to listen to the radio.
5. Channels normally used by recreational boaters are those that include the
term “non-commercial” in the Channel Use column of the chart. Some of
these are shared with other users and some are used only in certain geo-
graphic regions.
6. Marine vessels equipped with VHF radios are required to monitor Channel 16.
