Precautions to be taken in Operation
1. Do not proceed to the operation of equipment before thoroughly
reading the operation manual.
2. This equipment requires the licenses to operate a radio station and to
be engaged in radio operations.
You need obtain both radio station and radio operator licenses to
operate the equipment.
3. Except for maintenance inspection, do not unnecessarily open the
equipment in the interior nor touch any internal parts and adjustable
portions.
4. The equipment employs a 100V AC(220V AC) power source in the
interior. Touching an internal part, therefore, may cause you to suffer
from an electric shock.
100V position for 85VAC to 132VAC.
220V position for 170VAC to 264VAC
Do not open the equipment in the interior nor touch any internal parts
inadvertently.
5. The equipment is powered at 100V AC. (or 220V AC as switched) or
at 13.6V DC. To apply any voltage other than these, it is necessary to
provide a converter.
6. With the dc power applied, do not mistake positive and negative poles
upon connection. Check and ensure the drawing. [DC IN] (J101) has
No. 2 Terminal positive and No. 1 negative.
7. With the ac power applied, check to know whether the power available
is rated at 100 volts or 220 volts. To this voltage, set the selector switch
located on the back.
8. Avoid locating the equipment at a hot and highly humid place or
exposed to the direct sunlight.
9. Should the equipment unfortunately fail, or if you place an order or
make an inquiry for an optional accessory or accessories, please make
contact with our Tokyo Sales Division, Local branch, sales office or
agent.

1. Outline
The JRV-500B VHF TRANSCEIVER (after called JRV-500B) is shore basis
communication equipment for maritime communication system in 150MHz RR
band, is designed to satisfy the ITU radio regulation (RR). It attends the simplex
and duplex communications under operating conditions with 24H-hours
operation.
The desktop type or rack-mount type can be selected according to the
operating conditions. The full synthesizer controlled by a high performance
microprocessor has eliminated a crystal oscillator, which hitherto have been
needed for each channel.
The maritime mobile service radio communication channels are saved in
EEPROM. The operator can call up any desired channel on the spot.
Features:
1) The JRV-500B can be operated 24-hours a day.
2) Either desk top-type or rack-mount type can be selected.
3) Direct channel mode and memory channel mode are provided.
4) Up to specified eight channels can be saved in EEPROM.
(memory channel mode)
5) The microprocessor allows easy operation.
6) The external control is prepared for RS-422 and parallel ports.
7) The DC power supply is automatically changed even if the AC power
supply fails. (AC power supply type)
8) 4wires remote control mode is optionally possible. (with Modem)
