Operating Precautions
To avoid electrical shock, never touch the inside of the scanner or
display unit. Leave protective cover on.
High voltage present inside of these units could cause personal injury.
Refer equipment servicing to authorized JRC personnel.
Avoid routinely entering the nearby vicinity of the scanner unit.
The scanner unit rotates quickly and could cause personal injury. The
scanner should be installed in a high place such as the cabin roof,
flying bridge, radar mast, or the top base frame of your ship. If the
scanner cannot be located out of normal human reach, it should be
surrounded with a fence. Prolonged human exposure to radar signals
at close range is not recommended.
Before approaching or removing the scanner unit, turn off the STBY/
OFF and X-MIT/OFF keys on the display unit. Cable connector P1 on
the display unit should be disconnected before removing the scanner
unit from its installed position.
Never sit on the scanner unit.
The radome and/or the parts in the scanner unit may be damaged.
Use your RADAR 2000 system properly by following the instructions
in this manual.
Incorrect operation can detract from optimum system performance.
This radar unit is only an aid to navigation. Its accuracy can be af-
fected by many factors including equipment failure or defects, envi-
ronmental conditions, and improper handling or use. It is the user’s
responsibility to exercise common prudence and navigational judge-
ment. This radar unit should not be relied upon as a substitute for such
prudence and judgment.

3.7 INITIAL OPERATION AND CHECK OUT
3.7.1 INSPECTION AFTER THE INSTALLATION
After completing the installation and prior to energizing the equipment, it is
necessary to assure that all the steps of the installation were accomplished in
accordance with the instructions.
(1) The cables are not crimped or damaged.
(2) The input voltage connected accurately.
(3) The securing bolts of all equipment is tightened.
(4) The connection of the power cable shield is made properly to RF
ground.
3.7.2 OPERATING INITIAL SETTING MENU
Press the JOYSTICK, and the initial setting menu will be appear on the screen.
The JOYSTICK is used to select a particular menu. The particular menu will be
highlighted character, then press the JOYSTICK.
3.7.3 RELATIVE BEARING ALIGNMENT
This alignment should be made when the radar unit is installed. Failure to per-
form this procedure can result in incorrect target bearing readings.
Proceed as follows:
① Identify a suitable targets (e.g. buoy, etc.) preferably between 0.5 and 1 NM
in range on the screen.
② Visually locate the target and line the bow of the vessel up with the target.
③ Put the EBL marker on the target.
④ Press and hold the JOYSTICK for the initial setting menu.
⑤ Select BEARING by using the JOYSTICK, press the JOYSTICK for the
bearing adjustment mode.

⑧ Press the JOYSTICK to end the bearing adjustment mode.
3.7.4 DISPLAY TIMING (ZERO NM ADJUSTMENT)
This alignment must be made when the radar unit is installed. Failure to per-
formed this procedure can result in correct target distance readings. Set the
range at 0.25 NM and observe a target at a known (nearest) distance.
① Locate a straight dock, sea wall or bridge.
Press and hold the JOYSTICK for the initial setting menu.
② Select DISPLAY TIMING by using the JOYSTICK, and press the JOY-

To turn off the #2 EBL, selects the FUNCTION-#2 EBL-OFF on the
menu sheet.
4.13 SETTING GUARD
The Guard Zone may be zone completely surrounding the vessel or a partial
trapezoidal zone to monitor targets entering or departing the specified area.
The guard zone will sound audible and visual alerts to the operator. In the IN
mode, an alarm will sound if a target enters the area. The IN alarm is effective
for alerting the operator to targets approaching his vessel. In the OUT mode,
the alarm will sound if a target leaves the prescribed area. This type of alarm is
useful for monitoring as an anchor watch, or pair trawling.
① Press the GUARD key.
② Set the cross cursor to the start point using the JOYSTICK and press the
JOYSTICK.
③ To determine the Guard Zone width, set the cross cursor using the JOY-
STICK and press the JOYSTICK.
④ To determine the bearing limits of the Guard Zone, set the cross cursor
using the JOYSTICK and press the JOYSTICK. We now have a sector zone
which alarm if any target enters the zone with the guard zone alarm indica-
tor “GUARD I 4” which indicates IN alarm mode is in operation and the
alarm target sensitivity is set at 4.
⑤ Press the GUARD key again and the symbol will change to “GUARD O 4”
indicating that the OUT alarm will sound for targets leaving the guard zone.
⑥ Pressing the GUARD key again will turn off the Guard Zone.
To memorize an alarm zone, press and hold the GUARD key until the dis-
play beeps and the alarm character “GUARD I” turn into highlight at IN
mode alarm. At this time the zone will have been memorized for use at any
time.
To activate the memorized alarm zone, just press and hold the GUARD key
until the display beeps. Your memorized zone will reappear. The zone will
be displayed as an IN mode alarm. If you want to change to an OUT mode
alarm, press the GUARD key.

4.19 TRAIL
This feature allows the operator to see the past history of target movement as an
after-glow or trail behind the moving targets. The selecting “short” enables trail,
placing a short after-glow behind the moving targets. Selecting the “long” en-
ables trail with a longer after-glow.

erator the ability to make small targets appear larger on the display for better
viewing. When active, “EXP” is highlighted in the upper left area of the screen.

Interference Rejection (IR) mode can be set to on or off. The IR reduces noise
on the display caused by other radars. When active, the “IR” is highlighted on

RACON, you should turn off the IR mode to see the RACON signals.

tion and the range, bearing and TTG to MOB point be displayed in the lower
position of the display.

The TIMED-TX mode allows the operator to program the radar to automati-
cally transmit for a programmed period followed by a standby period. This
permits the user to maintain a radar watch while reducing the power consump-
tion experienced during full transmit operation. In TIMED-TX mode press the
STBY/OFF key and the radar will return to its normal operating mode.
