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 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:
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.

4. General Notes on Operating Marine VHF
4-1. Rules and Manners
The FM-2710 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.
• 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.
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 for maritime mobile stations (156.025 to
163.275 MHz).
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.
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 before 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 stubborn 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
CAUTION
Use the correct fuse.
Use of the wrong fuse can cause fire
or equipment damage.
30
To protect the transceiver from serious damage, a 10A fuse is provided in the snap-in
fuse holder onthe power cable. The fuse
protects against over-voltage/reverse polarity 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.
6. Troubleshooting
Minor Troubleshooting
Most of 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 TO CHECK INSIDE THE TRANSCEIVER. CARELESS HANDLING MAY CAUSE
PERMANENT DAMAGE TO THE TRANSCEIVER.
