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
Page 16
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.

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).

The message log stores 50 each of the latest received
routine messages (other than Distress), received
distress messages, and transmitted messages, each
type in its own memory. When a message log memory
becomes full the oldest message in that memory is
automatically erased to make room for the latest. The
log file with the message of “
unread or unacknowledged Rx messages,
unacknowledged Tx messages and unread distress
messages.
The messages are saved to correspond logs as follows.

Routine), Group (Routine)
• RCVD. (Received) DISTRESS: Distress, Distress Ack,

5. Maintenance
The FM-2721 is designed to provide years of troublefree operation. It is, however, recommended to inspect
and maintain the following points to minimize the
possibility of equipment failure and assure optimum
performance. Be sure to disconnect the power cable at
the fuse holders before performing any maintenance
work.
5.1 Antenna Check
Since the antenna is exposed to direct sunlight and salt
water spray, it is subject to corrosion or salt water
immersion at the antenna base. Physical damage, such
as a crack, may occur under heavy ship’s vibration. If
cracks or water immersion is found, contact FURUNO
dealer for servicing.
5.2 Cleaning of Transceiver, Handset
5.3 Fuse Replacement
A 10A fuse in the snap-in fuse holder on the power
cable protects the equipment from reverse polarity and
equipment fault. If the fuse has blown, first find the
cause of the problem before replacing it. Use only a
10A fuse; use of other fuses will damage the equipment
and void the warranty.
CAUTION
Use the proper fuse.
Use of a wrong fuse can cause fire or
equipment damage and void the warranty.
5.4 Battery Check
Keep the transceiver and handset clean and dry at all
times. Dust or loose dirt accumulated on them should
be wiped off with a soft, dry cloth. Never use plastic
solvents, such as thinner or acetone for cleaning; they
may dissolve paint and markings.
Check all connectors for corrosion. If corroded, clean
the contact and re-tighten securely.
The FM-2721 operates normally at any voltage between
10.8 and 15.6 VDC. If the battery voltage is out of
ratings, check the battery liquid and the charging
system of your boat. Check also rust or corrosion at the
battery terminals and the ship’s mains switch-board for
poor contact.

6. Troubleshooting
6.1 Easy T roubleshooting
Most VHF troubles are caused not by the transceiver itself but by the ANT/feeder or power supply system. The list
below provides simple troubleshooting that can be done by the operator. DO NOT ATTEMPT T O CHECK INS IDE THE
EQUIPMENT. CARELESS HANDLING MAY CAUSE PERMANENT DAMAGE TO THE TRANSCEIVER.
Symptom Possible Cause Remedy

General Notes on Operating Marine VHF
Rules and Manners
The FM-2721 fully complies with the requirements for international maritime VHF radio service. It is intended to be
used by a person who holds a valid radio operator’s license and station call sign.Below are some important rules,
regulations and manners for operating the equipment.
Whenever the radio is turned on, keep watch on CH16 for distress or calling message.
•
Distress communications have absolute priority. If you hear MAYDAY, talk only if you can help, and be prepared to
•
offer assistance or relay the distress message.
Use appropriate channels.
•
Listen before transmitting to avoid interfering with other communications.
•
The ship Radiotelephone Station Licensee is responsible for recording in a communication log all contacts made
•
over the telephone and watch period on CH16. All distress, emergency and safety messages must be recorded in
detail. Entries must show boat’s name, call sign, watch start/stop times, and operator’s signature. Use 24-hour
notation to record time.
Radio waves are public property. Keep all communications as brief and clear as possible.
•
Declare ID or call sign at the beginning and end of each communication.
•
Do not divulge contents of communications nor use them for private benefit without permission. (This does not
•
apply to distress communication.)
Be aware that many people are listening. Do not use indecent or profane language.
•
48
Page 63
Communication Dista nce
The FM-2721 operates on the VHF band assigned for maritime mobile stations.
The VHF radio wave, unlike LF or HF, propagates like a light ray. Thus communication is only available with another
VHF antenna which is above the horizon. This is called line-of-sight.
Even if a clear line-of-sight condition exists, the radio wave is attenuated along the signal path. The communication
distance is limited also by transmitter power, antenna efficiency and receiver sensitivity.
The average communication range, using 25 W marine VHF, is 10 to 15 nm for ship-to-ship and 20 to 30 nm for
ship-to-shore.
Note that an obstruction in the signal path, such as a large ship, crane, building or mountain, can destroy VHF
communications even for a short distance.
