IMPORTANT

READ THIS INSTRUCTION MANUAL CAREFULLY

before attempting to operate the transceiver.

SAVE THIS INSTRUCTION MANUAL

—This manual

contains important safety and operating instructions for
the IC-M710RT MF/HF MARINE TRANSCEIVER.

EXPLICIT DEFINITIONS

The explicit definitions described below apply to this
instruction manual.

NOTE:

The IC-M710RTGMDSS version has a

high-stability crystal oscillator unit. This unit draws a
slight current even when power to the transceiver
is OFF. To prevent battery exhaustion when dock-
ing your vessel for extended periods, unplug the
DC cable from the DC power receptacle.

PRECAUTIONS

WORD

DEFINITION

R

WARNING

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.

R

WARNING!

NEVER

connect the transceiver to an

AC outlet directly. This may pose a fire hazard or re-
sult in an electric shock.

R

WARNING!

NEVER

mount the transceiver over-

head. The weight of the transceiver is approximately 8
kg., 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.

Place unit in a secure place to avoid inadvertent use
by children.

NEVER

expose the transceiver to rain, snow or any

liquids.

There are two types of grounding systems available for
the IC-M710RT—Negative Ground and Floating
Ground—

NEVER

install the negative ground type to a

plus-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.

AVOID

using or placing the transceiver in areas with

temperatures below –20°C (–4°F) or above +60°C
(+140°F).

AVOID

connecting the transceiver to a power source

using reverse polarity. This connection will not only
blow fuses but may also damage the transceiver.

AVOID

placing the transceiver in excessively dusty en-

vironments or in direct sunlight.

AVOID

placing the transceiver against walls or putting

anything on top of the transceiver. This will obstruct
heat dissipation.
