IMPORTANT
READ THIS INSTRUCTION MANUAL CARE-
FULLY before attempting to operate the transceiver.
SAVE THIS INSTRUCTION MANUAL. This
manual contains important safety and operating in-
structions for the IC-910H.
EXPLICIT DEFINITIONS
i
R WARNING HIGH VOLTAGE! NEVER at-
tach an antenna or internal antenna connector during
transmission. This may result in an electrical shock or
burn.
R NEVER apply AC to the [DC13.8V] jack on the
transceiver rear panel. This could cause a fire or ruin
the transceiver.
R NEVER apply more than 16 V DC, such as a 24
V battery, to the [DC13.8V] jack on the transceiver rear
panel. This could cause a fire or ruin the transceiver.
R NEVER let metal, wire or other objects touch any
internal part or connectors on the rear panel of the
transceiver. This may result in an electric shock.
R NEVER expose the transceiver to rain, snow or
any liquids.
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
permanent damage to the transceiver if left there for
extended 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.
Place unit in a secure place to avoid inadvertent use
by children.
During mobile operation, DO NOT operate the trans-
ceiver without running the vehicle’s engine. When the
transceiver power is ON and your vehicle’s engine is
OFF, the vehicle’s battery will soon become exhaust-
ed.
Make sure the transceiver power is OFF before start-
ing the vehicle. This will avoid possible damage to the
transceiver by ignition voltage spikes.
During maritime mobile operation, keep the transceiv-
er and microphone as far away as possible from the
magnetic navigation compass to prevent erroneous in-
dications.
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-910H may
damage the transceiver.
