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.
