PREFACE
Thank you for purchasing the JRC JMA-900B Chart RADAR.
This manual describes how to install the equipment. For the best operation and
performance results, read this manual thoroughly before insallation.
For preventing electric shock and for securing periformance, grounding work is
needed.
Make sure to perform earth connection.
For the detailed operation, refer to the Instruction Manulal for JMA-900B.

●Before Operation ●
Pictorial Indication
Various pictorial indications are included in this manual and are shown
on the component equipment so that you can operate them safely and
correctly and prevent any danger to you and / or to other persons and
any damage to your property during operation. Such indications and
their meanings are as follows.
Please understand them before you read this manual:
This indication is shown where any person is supposed to be in

This indication is shown where any person is supposed to be injured
or any property damage is supposed to occur if this indication is
neglected or equipment is not operated correctly.
Examples of pictorial indication
The △mark represents CAUTION (including DANGER and
WARNING).
Detailed contents of CAUTION (“Electric Shock” in the example on the
left) are shown in the mark.
The mark represents prohibition.
Detailed contents of the prohibited action (“Disassembling Prohibited”
in the example on the left) are shown in the mark.
The ●mark represents instruction.
Detailed contents of the instruction (“Disconnect the power plug” in the
example on the left) are shown in the mark.
Warning label
There is a warning label on the top cover of the equipment.
Do not try to remove, break or modify the label.

iii
●Precautions upon Equipment Operation ●
Before installing the power cable, make sure to turn off the braker of the main
power line. Otherwise, an electric shock or a malfunction may occur.
When connecting/disconnecting the connection cables between the external
equipment, make sure to turn off the braker of the main power line.
Otherwise, a fire or an electric shock may occur.

iv
Do not touch the LAN/USB connectors directly with your hands.
Otherwise, a malfunction may occur due to electrostatic charges.
Divert electrostatic charges by touching chassis before accessing LAN/USB
connectors.
