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-703.
EXPLICIT DEFINITIONS
RWARNING RF EXPOSURE! This device emits
Radio Frequency (RF) energy. Extreme caution should be
observed when operating this device. If you have any
questions regarding RF exposure and safety standards
please refer to the Federal Communications Commission
Office of Engineering and Technology’s report on Evalu-
ating Compliance with FCC Guidelines for Human Radio
Frequency Electromagnetic Fields (OET Bulletin 65).
RWARNING HIGH VOLTAGE! NEVER attach an
antenna or internal antenna connector during transmis-
sion. This may result in an electrical shock or burn.
RNEVER apply AC to the [DC13.8V] receptacle on the
transceiver rear panel. This could cause a fire or damage
the transceiver.
RNEVER apply more than 16 V DC, such as a 24 V
battery, to the [DC13.8V] receptacle on the transceiver
rear panel. This could cause a fire or damage the trans-
ceiver.
RNEVER 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 rear panel 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 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-703 may damage the
transceiver.
Beat signals may be heard on some frequencies.
These will occur as a result of circuit construction.
For U.S.A. only
Caution: Changes or modifications to this transceiver, not
expressly approved by Icom Inc., could void your authority
to operate this transceiver under FCC regulations.
PRECAUTION
WORD DEFINITION
RRWARNING Personal injury, fire hazard or electric
shock may occur.
CAUTION Equipment damage may occur.
NOTE
If disregarded, inconvenience only. No
risk or personal injury, fire or electric
shock.
