HF MARINE TRANSCEIVER

iM710

IMPORTANT

READ THIS INSTRUCTION MANUAL CAREFULLY before attempting to operate the transceiver.

SAVE THIS INSTRUCTION MANUAL—This instruction manual contains important safety and operating instructions for the IC-M710.

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.

DISPOSAL

The crossed-out wheeled-bin symbol on

your product, literature, or packaging reminds you that in the European Union, all electrical and electronic products, batteries, and accumulators (rechargeable batteries) 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, Icom Inc. and the Icom logo are registered trademarks of Icom Incorporated (Japan) in Japan, the United States, the United Kingdom, Germany, France, Spain, Russia, Australia, New Zealand, and/or other countries.

PRECAUTIONS

RWARNING! NEVER connect the transceiver directly to an AC outlet. This may pose a fire hazard or result in an electric shock.

RWARNING! NEVER mount the transceiver overhead. 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 operation of the ship or vehicle may be hindered or where it could cause bodily injury.

NEVER allow children to play with equipment containing 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 alcohol when cleaning, as they can damage the transceiver’s surfaces.

i

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 erroneous indications.

USE an Icom microphone and/or handset only (supplied 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 environments, or in direct sunlight.

DO NOT place the transceiver against walls, or putting anything on top of the transceiver. This will obstruct heat dissipation.

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.

1 OPERATING RULES AND GUIDELINES

CALL PROCEDURES

Calls must be properly identified and time limits must be respected.

q Give your call sign each time you call another vessel or coast station. If you have no call sign, identify your vessel name and the name of the licensee.

w Give your call sign at the end of each transmission that lasts more than 3 minutes.

e You must break and give your call sign at least once every 15 minutes. during long ship-to-shore calls.

r Keep your unanswered calls short, less than 30 seconds.

Do not repeat a call for 2 minutes.

t Unnecessary transmissions are not allowed.

PRIORITIES

q Read all rules and regulations pertaining to priorities and keep an up-to-date copy handy. Safety and distress calls take priority over all others.

w False or fraudulent distress calls are prohibited and punishable by law.

PRIVACY

q Information overheard but not intended for you cannot be lawfully used in any way.

w Indecent or profane language is prohibited.

LOGS

q All distress, emergency and safety calls must be recorded in complete detail. Log data activity is usually recorded in 24 hour time. Universal Time (UTC) is frequently used.

w Adjustments, 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 authorized licensed technician performing or supervising 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 government agency for a Ship-Radiotelephone license application. This government-issued license states the call sign which is your craft’s identification for radio purposes.

(2) OPERATOR’S LICENSE

A Restricted Radiotelephone Operator Permit is the license 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 entries.

Keep a copy of the current government rules and regulations handy.
