DO NOT
use harsh solvents such as benzine or al-
cohol to clean the transceiver, as they will damage
the transceiver's surfaces. If the transceiver becomes
dusty or dirty, wipe it clean with a soft, dry cloth.
DO NOT
operate or place 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) in direct sunlight, result-
ing in permanent damage to the transceiver if left there
for extended periods.
DO NOT
place the transceiver in excessively dusty
environments or in direct sunlight.
DO NOT
place the transceiver against walls or put
anything on top of the transceiver. This will obstruct
heat dissipation.
Place the transceiver in a secure place to avoid inad-
vertent use by children.
NEVER
During mobile operation,
er where air bag deployment may be obstructed.
During mobile operation,
ceiver where hot or cold air blows directly onto it.
DO NOT
During mobile operation,
ceiver without running the vehicle's engine. When trans-
ceiver 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 start-
ing the vehicle engine. This will avoid possible dam-
age to the transceiver 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
operating the transceiver continuously for long periods
of time.
BE CAREFUL!
If a linear amplifier is connected,
set the transceiver's RF output power to less than the
linear amplifier's maximum input level, otherwise, the
linear amplifier will be damaged.
Use only supplied or optional Icom microphones.
Other manufacturer's microphones have different
pin assignments, and connecting to the IC-78 may
damage the transceiver.
