ALL MODE TRANSCEIVER

i910H

IMPORTANT

READ THIS INSTRUCTION MANUAL

CAREFULLY 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

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 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.

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 ex-

hausted.

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 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

operating 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.
