1. Installation

1.1 Mounting

Transceiver unit

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;

	Standard	Steering
Transceiver unit	0.95 m	0.65 m
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 necessary, reinforce the mounting location by doubling plate.

•Fasten the unit with four tapping screws (supplied).

Handset (Hanger)

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.

Remove six screws to remove the hanger cover, and fasten the hanger with two tapping screws (supplied) on the desktop or bulkhead.

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.

ANT

Connect the antenna cable (option) here. Use the optional antenna kit (RG-58/C/U cable).

(Input):

•GLL: Latitude and longitude

•RMC: Generic navigation information

•GGA: GPA position, UTC
