Transceiver Location

Select the mounting location for the transceiv er considering the following:
! Though the equipment is spray-proof, prolonged exposure to the environment can shorten its life . It is

recommended to install the equipment in the cabin or at least in a shaded place.

! The equipment should be located as near to the power source as possib le, and as f ar apart as possible

from any devices that ma y cause interf erence such as direction finders , navigation receiv ers and other
onboard electronics.

! The cabinet of the equipment, especially the rear panel, gets warm after a long transmission.

Therefore, provide some space around the transceiver to allow f or circulation of cooling air.

Compass safe distance

Standard: 1.7m
Steering : 0.8m

2-3. Mounting The T ransceiver

2-3-1. Transceiver Mounting Methods

The equipment can be mounted on the overhead, a tab letop or a bulkhead. The mounting location should
be able to support the weight of the unit.
If necessary , reinforce the mounting location by lining block or doubling plate.

The FM-2710 has a built-in speaker. How ever, if an external loudspeaker (4 W/4 ohms) is desired,
connect it to external speaker cab le .

2-3-5. Antenna Connection

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 f ollo wing requirements , may be arranged locally.
A high-gain antenna is preferab le . If you are not sure, consult with your dealer.

• Frequency r ange: 155 MHz to 164 MHz

• Impedance: 50 ohms

• Polarization: Vertical

• Input power: 30 W

• Quality: Able to withstand marine environment

Any 50 ohm coaxial cable heavier than 5D-2V (equivalent to RG-212/U) may be used for the connection
between the antenna and the transceiver. To extend the antenna cable longer than 20 m, use heavier
coaxial cable, such as 8D-2V or RG-213/U, to minimize power loss and signal attenuation through the
cable. Make sure to leave some slack in the cable loop behind the transceiver for service and
maintenance ease.

2. Select the desired channel b y rotating the Channel selector.

3. To set the transmitter to high or low power, press [1/25]/DIM key and release within 1 second.
This alternately changes the transmitter output power from 1 watt ("LOW" appears) to 25 watts ("LOW"
disappears).

Transmit at low pow er for short range communications or when in harbor areas, to minimize interference
to others.

Note: The f ollowing channels are automatically set to low power (1 watt):

USA: 13*, 17, 67*, 77
* Channels 13 and 67 can be switched to high pow er (25 W) if [1/25]/DIM key is pressed while [PTT]
switch is on.

Transceiver is designed not to transmit on US channel 15.

24

4. Pick up the microphone, press the [PTT] switch, and then call the party you want to talk with. Hold
the microphone fairly close to your mouth and speak clearly.

Press and hold the [PTT] switch to talk, and release it to listen for the response.

If the [PTT] switch is held f or more than 5 minutes , transmit function is disab led, a beep sound, and "to"
(time out) blinks instead of the channel display. This condition continues until the [PTT] switch is
released.

IMPORTANT:

CH16 is used in all USA coastal areas to call the Coast Guard and for general vessel calling. In certain
high traffic areas, CH09 is also used as the Hailing F requency. Please check with your local Coast Guard.

4. General Notes on Operating Marine VHF

4-1. Rules and Manners

The FM-2710 fully complies with the requirements for international maritime VHF r adio 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 f or oper ating 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 rela y the distress message.

• 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, w atch 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.

26

• Declare ID or call sign at the beginning and end of each communication.

• Use appropriate channels.

• 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.

27

4-2. Communication Distance

The FM-2710 operates on the VHF band assigned f or maritime mobile stations (156.025 to

163.275 MHz).
The VHF radio w a ve , unlike LF or HF, propagates like a light ray. Thus comm unication is only av ailable with
another VHF antenna which is abo v e the horizon. This is called line-of-sight.

Even if a clear line-of-sight condition e xists, the radio wave is attenuated along the signal path. The
communication distance is limited also by transmitter pow er, 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, b uilding or mountain, can destro y
VHF communications even for a short distance.

28

5. Maintenance

The FM-2710 is designed to provide years of trouble-free 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 bef ore performing any
maintenance work.

5-1. Cleaning of Transceiver

Cabinet, LCD

Keep the unit clean and dry at all times. Dust or loose dirt accumulated on the front panel and knobs
should be wiped off with a soft, dry cloth. For stub born dirt, use mild detergent and water on a cotton
tipped swab or soft cloth. Never use plastic solvents, such as thinner or acetone for cleaning; they may
dissolve paint coating/marking on the front panel and cabinet case.

Connectors

Check all connectors for foreign material and corrosion. If corroded, clean the contact and re-tighten
securely.

29

5-2. Antenna System 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.

5-3. Battery Check

The FM-2710 operates normally at any voltage between 11 and 15 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.

5-4. Fuse Replacement

To protect the transceiver from serious dam-

age, a 10A fuse is provided in the snap-in

CAUTION

Use the correct fuse.
Use of the wrong fuse can cause fire
or equipment damage.

fuse holder onthe power cable. The fuse

protects against over-voltage/reverse polar-

ity of the ship's mains or internal fault of the

equipment. If the fuse has blown, first find

the cause of the problem before replacing it.

30

6. T roubleshooting

Minor T roubleshooting

Most of VHF troub les are caused not by the transceiver itself but by the ANT/f eeder or po w er supply
system. The list below provides simple troubleshooting that can be done by the oper ator. DO NOT
ATTEMPT TO CHECK INSIDE THE TRANSCEIVER. CARELESS HANDLING MAY CAUSE
PERMANENT DAMAGE TO THE TRANSCEIVER.

Symptom Possible Cause Remedy

Power is off at mains switchboard. Turn mains switch o n.

Secure connector firmly and check
connections to battery.
Check battery liquid, charging
system, etc.
Check mains voltage and polarity
and then replace fuse (10A).
