RWARNING HIGH VOLTAGE! NEVER attach
an antenna or internal antenna connector during trans-
mission. This may result in an electrical shock or burn.
RNEVER apply AC to the [DC13.8V] socket on the
transceiver rear panel. This could cause a fire or ruin
the transceiver.
RNEVER apply more than 16 V DC, such as a 24 V
battery, to the [DC13.8V] socket on the transceiver rear
panel. This could cause a fire or ruin the transceiver.
RNEVER let metal, wire or other objects touch any
internal part or connectors on the rear panel of the
transceiver. This will cause electric shock.
RNEVER expose the transceiver to rain, snow or
any liquids.
NEVER allow children to play with the transceiver.
AVOID using or placing the transceiver in areas with
temperatures below –10°C (+14°F) or above +60°C
(+140°F). Be aware that temperatures on a vehicle’s
dashboard can exceed 80°C (+176°F), resulting in per-
manent damage to the transceiver if left there for ex-
tended periods.
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.
During mobile operation, DO NOT operate the trans-
ceiver without running the vehicle’s engine. When
transceiver power is ON and your vehicle’s engine is
OFF, the vehicle’s battery will soon become exhausted.
Make sure the transceiver power is OFF before starting
the vehicle. This will avoid possible damage to the
transceiver by ignition voltage spikes.
During maritime mobile operation, keep the transceiver
and microphone as far away as possible from the mag-
netic navigation compass to prevent erroneous indica-
tions.
BE CAREFUL! The heatsink will become hot when op-
erating the transceiver continuously for long periods.
BE CAREFUL! If a linear amplifier is connected, set
the transceiver’s RF output power to less than the lin-
ear amplifier’s maximum input level, otherwise, the lin-
ear amplifier will be damaged.
Use Icom microphones only (supplied or optional).
Other manufacturer’s microphones have different pin
assignments and connection to the IC-756 may dam-
age the transceiver.

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 elec-
tric shock.
The explicit definitions described at left apply to this in-
struction manual.
The IC-756 complies with the essential requirements of
the 89/336/EEC directive for Electromagnetic Compati-
bility. This compliance is based on conformity with the
ETSI specification prETS300 684 (EMC product stan-
dard for Commercially Available Amateur Radio Equip-
ment).
