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.
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.
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.

iv
Precautions Upon the Operation
CAUTION
Do not use the equipment in the environment other than those provided in the
specification. Doing so may result in equipment failure, malfunction, or injury.
Do not install the equipment in the place subject to vibration or shock.
Doing so may result in the equipment falling or collapsing, resulting in
equipment failure or injury.
Do not place any item on the 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.
Do not install the display unit in the location where it may come in contact with
water, oil, or chemicals. Doing so may result in equipment failure,
malfunction, or injury.
This equipment is not designed to automatically make judgments on the
position data. The navigation information including the position data needs to
be judged by the user himself.
Do not use benzine, alcohol or thinner when caring this equipment.
Doing so may result in removing the paint or changing of properties.
Wipe off the grime lightly with a dry soft cloth.
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 battery.
Failure to do so may result in equipment failure or malfunction.

v
When connecting the cable attached to the equipment, do not bend it acutely, twist
it, or impart excessive force. Doing so sometimes causes cracks or damage to the
coating, resulting in fire or electrocution.
Do not install the sensor where there is excessive vibration.
Vibration may cause sensor failure.
Do not paint the sensor.
Doing so may result in reception problems.
Do not install the sensor where temperature exceeds 55 degrees Celsius and
there is covered with exhaust gas from funnel . Doing so may result in equipment failure
or malfunction.
Use the fit cable, when connecting to the junction box.
The Junction box rubber gaskets (25 f Gland side) fit 10mm – 20mm cables.
Install the sensor where there are no obstacles, in order to ensure that GPS signals
can be directly received from satellites without interference or reflection of signals
from surrounding objects.
Whenever possible, select a place with the following characteristics.
If it is difficult to find an ideal site, select a place temporarily and install the equipment. Conduct a
test to make sure that the proper performance can be obtained and then fix the equipment in
position. If it is installed at an improper place, reception accuracy may be impaired.
CAUTION
1. An open space, which allows uniform reception of satellite signals.
2. Far away from any high power transmission antennas.
3. Outside radar beams.
4. Away from the INMARSAT antenna by at least 5 meters and outside
the INMARSAT beam.
5. Away from the antenna of a VHF transmitter and a direction finder
by at least 3 meters.
6. Away from a Magnetic Compass by at least 1 meter.
7. 3 meters or more away from amateur radio antennas.

Section 1 Equipment Overview
1.1 Functions
This equipment (JLR-7900/JLR-7600) is a GPS navigator with a JLR-4341 DGPS or JLR4340
GPS sensor being connected to the NWZ-4610 display unit.
The GPS navigator operates around-the-clock to measure the position with high accuracy
anywhere in the world and in all weather conditions by using the GPS satellites. In addition, the
GPS navigator can increase the accuracy of position fixing by receiving correction data from the
DGPS beacon station and SBAS satellites.
1.2 Features
●Availability of three output ports
●High visibility by using 4.5-inch liquid crystal display
●Improvement of operability by using various menus
●Built-in SBAS function
●Built-in RAIM function
