IMPORTANT
READ THIS INSTRUCTION MANUAL CAREFULLY
before attempting to operate the transceiver.
SAVE THIS INSTRUCTION MANUAL—This instruc-
tion manual contains important safety and operating
instructions for the IC-M710.
PRECAUTIONS
EXPLICIT DEFINITIONS
The explicit definitions described below apply to this
instruction manual.
WORD DEFINITION
RWARNING Personal injury, fire hazard or electric
shock may occur.
CAUTION Equipment damage may occur.
NOTE If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.
RWARNING! NEVER connect the transceiver di-
rectly to an AC outlet. This may pose a fire hazard or
result in an electric shock.
RWARNING! NEVER mount the transceiver over-
head. The weight of the transceiver is approximately
7.8 kg. (17.4 lb), but its apparent weight will increase
several fold due to wave shocks and vibration. The
transceiver must be mounted on a flat hard surface
only.
NEVER connect a power source of more than 16 V
DC, such as a 24 volt battery. This connection will ruin
the transceiver.
NEVER place the transceiver where normal opera-
tion of the ship or vehicle may be hindered or where it
could cause bodily injury.
NEVER allow children to play with equipment contain-
ing a radio transmitter.
NEVER expose the transceiver to rain, snow or any
liquids.
NEVER install the IC-M710 into a positive-grounding
ship. Such a connection might blow fuses, and is not
usable.
DO NOT use chemical agents such as benzene or al-
cohol when cleaning, as they can damage the trans-
ceiver’s surfaces.
In maritime mobile operation, KEEP the transceiver
and microphone as far away as possible (at least 1 m)
from the magnetic navigation compass to prevent er-
roneous indications.
USE an Icom microphone and/or handset only (sup-
plied or optional). Other brands may have different pin
assignments and may damage the transceiver.
DO NOT use or place the transceiver in areas with
temperatures below –20°C (–4°F) or above +60°C
(+140°F).
DO NOT connect the transceiver to a power source
using reverse polarity. This connection will not only
blow fuses but may also damage the transceiver.
DO NOT place the transceiver in excessively dusty en-
vironments, or in direct sunlight.
DO NOT place the transceiver against walls, or putting
anything on top of the transceiver. This will obstruct
heat dissipation.
DISPOSAL
The crossed-out wheeled-bin symbol on
your product, literature, or packaging re-
minds you that in the European Union, all
electrical and electronic products, batter-
ies, and accumulators (rechargeable bat-
teries) must be taken to designated
collection locations at the end of their working life. Do
not dispose of these products as unsorted municipal
waste. Dispose of them according to the laws in your
area.
Icom is not responsible for the destruction, damage to, or
performance of any Icom or non-Icom equipment, if the
malfunction is because of:
• Force majeure, including, but not limited to, fires,
earthquakes, storms, floods, lightning, other natural
disasters, disturbances, riots, war, or radioactive
contamination.
• The use of Icom transceivers with any equipment that is
not manufactured or approved by Icom.

OPERATING RULES AND GUIDELINES
❑ CALL PROCEDURES
Calls must be properly identified and time limits must
be respected.
qGive your call sign each time you call another ves-
sel or coast station. If you have no call sign, identify
your vessel name and the name of the licensee.
wGive your call sign at the end of each transmission
that lasts more than 3 minutes.
eYou must break and give your call sign at least once
every 15 minutes. during long ship-to-shore calls.
rKeep your unanswered calls short, less than 30
seconds.
Do not repeat a call for 2 minutes.
tUnnecessary transmissions are not allowed.
❑ PRIORITIES
qRead all rules and regulations pertaining to priori-
ties and keep an up-to-date copy handy. Safety and
distress calls take priority over all others.
wFalse or fraudulent distress calls are prohibited and
punishable by law.
❑ PRIVACY
qInformation overheard but not intended for you can-
not be lawfully used in any way.
wIndecent or profane language is prohibited.
❑ LOGS
qAll distress, emergency and safety calls must be re-
corded in complete detail. Log data activity is usu-
ally recorded in 24 hour time. Universal Time (UTC)
is frequently used.
wAdjustments, repairs, channel frequency changes
and authorized modifications affecting electrical
operation of the equipment must be kept in the
maintenance log; entries must be signed by the au-
thorized licensed technician performing or supervis-
ing the work.
❑ RADIO LICENSES
(1) SHIP STATION LICENSE
You must have a current radio station license before
using the transceiver. It is unlawful to operate a ship
station which is not licensed.
Inquire through your dealer or the appropriate govern-
ment agency for a Ship-Radiotelephone license appli-
cation. This government-issued license states the call
sign which is your craft’s identification for radio pur-
poses.
(2) OPERATOR’S LICENSE
A Restricted Radiotelephone Operator Permit is the li-
cense most often held by small vessel radio operators
when a radio is not required for safety purposes.
The Restricted Radiotelephone Operator Permit must
be posted or be kept with the operator. Only a licensed
radio operator may operate a transceiver.
However, non-licensed individuals may talk over a
transceiver if a licensed operator starts, supervises,
and ends the call, and makes the necessary log en-
tries.
Keep a copy of the current government rules and reg-
ulations handy.
