1. Installation
1.1 Mounting
Transceiver unit
Standard Steering
T ransceiver unit 0.95 m 0.65 m
The transceiver unit can be mounted on the overhead,
a desktop or on a bulkhead. Select the mounting
location considering the following:
•
It is recommended to install the equipment in the
cabin so as to avoid spray.
•
The equipment should be located as near to the
power source as possible, and as far apart as
possible from any devices that may cause
interference such as direction finders, navigation
receivers and other onboard electronics.
•
Compass safe distances (Standard compass,
Steering compass) are;
Handset and Bracket 2.05 m 1.40 m
Loudspeaker (option) 2.20 m 1.50 m
•
The cabinet of the equipment, especially the rear
panel, gets warm after a long transmission.
Therefore, provide some space around the unit to
allow for circulation of cooling air.
•
The unit can be mounted on the deck or a bulkhead.
The mounting location should be able to support the
weight of the unit.
•
If ne c e s sary, reinforce the mountin g location by
doubling plate.
•
Fasten the unit with four tapping screws (supplied).
1
For bulkhead mounting, tighten upper tapping
•
screws (supplied) and washers so there is 5 mm
clearance between bottom of screw head and
240
bulkhead, and screw slots of the unit. Then fasten
upper screws and washers.

The length of the hanger cable is 5 m (optional HS-2721/RB-2721B: 50 m), so locate the handset hanger within 5 m of
the transceiver unit.

Note: The magnet inside the hanger may pull the screwdriver when mounting the hanger.
3
Antenna Connection (option)
Provide a location as high and clear as possible, free from the influence of nearby antenna, rigging and masts.
However, any good quality antenna, complying with the following requirements, may be arranged locally. A high-gain
antenna is preferable. If you are not sure, consult with your dealer.
Frequency range: 155 MHz to 164 MHz
Impedance: 50 ohms
Polarization: Vertical
Input power: 25 W
Quality: Able to withstand marine environment
Any 50 ohm coaxial cable heavier than 5D-2V or RG58C/U may be used for the connection between the antenna and
the transceiver unit. Make sure to leave some slack in the cable loop behind the transceiver for service and
maintenance ease.
Lay the antenna, and then solder the M-type connector onto the cable end as shown on page 7.

Power Connection
Connect the power cable to the connector attached at the rear of the transceiver unit. The RED wire and the BLACK
wires, with inline fuses (10A), connect the transceiver unit to the ship’s 12 VDC power supply.
Note:The power cable supplied is 3 meters in length; however it could be shortened as much as possible to prevent
power loss.

Connect the 10P cable (supplied) here.
Ground ( )
While special grounding is not generally required for VHF radiotelephones, it is a good practice to properly ground all
electronic equipment to the ship’s ground system. The FM-2721 can be connected to ground by attaching a wire to the
ground screw on the transceiver unit’s rear panel and then to the nearest ship’s ground connection point.
