Precautions Upon the Operation

WARNING

Do not disassemble or modify the equipment. Doing so may result in fire,

electric shock, or equipment failure.

Do not allow the display to become wet. Doing so may result in fire, electric

shock, or equipment failure.

Operate the equipment only at the indicated voltage. Failure to do so may

result in fire, electric shock, or equipment failure.

Install this unit at least 1 m away from any magnetic compasses. Installation

near a magnetic compass may result in interference with the magnetic

compass, and may result in an accident.

Do not perform internal inspections or modifications of the equipment.

Inspection or modification by unauthorized personnel may result in fire, electric

shock, or equipment failure. Please consult with JRC or an affiliate to

perform internal inspections or repair.

When disposing of the used lithium battery, place insulating tape over the

battery terminals, or otherwise insulate the battery. Failure to do so may

result in heating, explosion, or fire due to a shorted battery.

Precautions Upon the Operation

CAUTION

Do not use the equipment in environments other than those provided in the

specifications. Doing so may result in equipment failure, malfunction, or

injury.

The dip switches on the unit are all set at the factory, and must not be

changed. Doing so may result in equipment failure, malfunction, or injury.

Do not install the display unit in locations where it may come in contact with

water, oil, or chemicals. Doing so may result in equipment failure,

malfunction, or injury.

Do not install the equipment in places subject to vibration or shock.

Doing so may result in the equipment falling or collapsing, resulting in

equipment failure or injury.

Do not place items on top of the equipment.

Doing so may result in equipment failure, malfunction, or injury.

Please consult with JRC or an affiliate to perform installation. Installation by

unauthorized personnel may result in malfunction.

Only use the specified batteries. Failure to do so may result in battery

leakage or rupture, resulting in fire, injury, or equipment failure.

Use the indicated screws when installing the display unit to a stable wooden

surface. Failure to do so may result in the display unit falling over, causing

injury or property damage.

Use only the specified fuse.

Failure to do so may result in fire or equipment failure.

Use only the specified batteries.

Failure to do so may result in equipment failure or malfunction.

CAUTION

Do not bend the cables included with this equipment excessively, or twist them or

subject them to other strong forces. Doing so may result in damage to the

interior or exterior of the cables, and may result in fire or electrocution.

Do not install the equipment in places subject to vibration or shock.

Doing so may result in the equipment failure due to reception problems.

This equipment uses GPS satellite signals to determine the bearing of the ship.

Install the sensor where there are no impediments to electrical signal reception,

and no signal reflection. If the sensor installation location environment is

unsatisfactory, ship bearing calculations is repeatedly interrupted.

If selection of the optimal installation location is difficult, and some concessions

must be made, place the sensor in the desired installation location and test the

acceptability of the sensor results before permanently installing the sensor.

Installing the sensor in an inappropriate location may result in decreased

accuracy and equipment failure.

Whenever possible, select a place having the following characteristics.

Out of the mast's

shadow.

(2 m or more

separation)

2 m or more outside of any radar beams.

Installation near radar antennas may result in multipath wave interference, which decreases the

accuracy of the equipment.

Whenever possible, keep the equipment out of any beams.

Away from the Inmarsat antenna by at least 5 m,

and out of the scope of the beam.

An open space which

allows uniform

reception of satellite

signals.

Section 1 Equipment Overview

1.1 Functions

This equipment determines the heading of a ship by measuring the orientation between two

antennas using the signal from GPS satellites.

The equipment not only determines the heading with high accuracy anywhere in the world and in

all weather conditions using the GPS satellites, but determines the position, course, and speed of

the ship. When the DGPS beacon receiver is connected, the accuracy of position fixing can be

enhanced by receiving correction data from the DGPS beacon station.

Since this equipment outputs the bearing information at high speed, if the unit is interfaced to a

JRC radar unit, it is possible to fully draw the capabilities of the radar and ARPA.

1.2 Features

●High accuracy and high stability (0.5 rms degree)

●Short setting time (less than 2 minutes at warm start fix)

●H

igh speed tracking response (Tracking rate of turn is 45 degree/sec)

●High visibility

5.7-inch FSTN LCD

●Many utility display modes (Compass rose graphics, ROT, NAV, GPS status, etc.)

●Easy installation

●Direct connection to the JRC radars
