JLR-7500/7800/NWZ-4740 GPS NAVIGATOR INSTRUCTION MANUAL

i
Foreword
Thank you for purchasing the JRC GPS Navigator JLR-7500/7800.
This equipment is a high-performance navigation equipment consisting of a DGPS/GPS
sensor and navigator, can retrieve the position data using the DGPS/GPS sensor to display
various navigation information on the display.
●Thoroughly read this instruction manual before operating the equipment.
●Keep this manual nearby the equipment to allow ready access to it if necessary. It may
provide valuable information on how to deal with a given situation that may arise during the
operation.

ii

cause death or serious injury if not observed.
CAUTION Instructions shown with this symbol represent what may
cause injury or property damage if not observed.
Examples of the Symbols
The symbols shown in the ∆mark represent those that require attention
(including potential dangers and warnings).
A depiction of the type of caution is shown inside the symbol (the left
symbol indicates a general caution).
The symbols shown in the [mark represent actions which are
prohibited. A depiction of the type of prohibited action is shown inside
the symbol (the left symbol indicates that disassembly is prohibited).
The Qsymbol indicates required actions. A depiction of the type of
required action is shown inside the symbol (the left symbol indicates that

iii
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.

iv
Precautions Upon the Operation
CAUTION
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 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 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.
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.
Use only the specified battery. 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 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.
The junction box rubber gaskets (φ25 Gland side) fit φ10 - 20 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.

Terminology
Term Meaning (Descriptions)
2D (2 dimension) Positioning with antenna elevation height in addition to satellite
data.
3D (3 dimension) The three dimensional position fix, 4 or more satellites required.
