PRECAUTIONS

R WARNING HIGH VOLTAGE! NEVER
antenna or internal antenna connector during transmis-
sion. This may result in an electrical shock or burn.
R NEVER
apply AC to the [DC13.8V] jack on the trans-
ceiver rear panel. This could cause a fire or ruin the trans-
ceiver.
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 in-
ternal part or connectors on the rear panel of the trans-
ceiver. This may result in an electric shock.
NEVER expose the transceiver to rain, snow or any liquids.
AVOID using or placing the transceiver in areas with tem-
peratures 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 envi-
ronments 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 transceiver
without running the vehicle's engine. When the trans-
ceiver's 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 trans-
ceiver by ignition voltage spikes.
During maritime mobile operation, keep the transceiver
and microphone as far away as possible from the magnetic
navigation compass to prevent erroneous indications.
BE CAREFUL! The heatsink will become hot when oper-
ating 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 linear am-
plifier's maximum input level, otherwise, the linear ampli-
fier will be damaged.
Use Icom microphones only (supplied or optional). Other
manufacturer's microphones have different pin assign-
ments, and connection to the IC-7400 may damage the
transceiver.
