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-718.
EXPLICIT DEFINITIONS
PRECAUTIONS
RWARNING HIGH VOLTAGE! NEVER at-
tach an antenna or internal antenna connector during
transmission. This may result in an electric shock or
burn.
RNEVER apply AC to the [DC13.8V] jack 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] jack 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 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
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
environments 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 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 magnetic navigation compass to prevent
erroneous indications.
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
linear amplifier’s maximum input level, otherwise, the
linear amplifier will be damaged.
Use Icom microphones only (supplied or optional).
Other manufacturer’s microphones have different
pin assignments, and connection to the IC-718 may
damage the transceiver.
WORD
R WARNING
CAUTION
NOTE
DEFINITION
Personal injury, fire hazard or electric
shock may occur.
Inconvenience only.
No risk of personal injury, fire or
electric shock.
Equipment damage may occur.
