PRECAUTIONS
R WARNING HIGH VOLTAGE! NEVER at-
tach an antenna or internal antenna connector during
transmission. This may result in an electrical shock or
burn.
RWARNING! NEVER operate the transceiver
with a headset or other audio accessories at high vol-
ume levels. Hearing experts advise against continuous
high volume operation. If you experience a ringing in
your ears, reduce the volume or discontinue use.
R CAUTION! NEVER change the internal set-
tings of the transceiver. This result in reduced trans-
ceiver performance and/or damage to the transceiver.
R CAUTION! NEVER touch the transceiver top
cover when transmitting continuously for long periods.
It will become hot.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, etc., might dam-
age the expensive final devices.
The transceiver warranty does not cover any problems
caused by unauthorized internal adjustment.
R CAUTION! The transceiver weighs approx. 25 kg
(55 lb). 2 peoples should be present to carry, lift up or
turn over the transceiver, etc.
R CAUTION! The socket-outlet must be near the
transceiver and must be easily accessible.
R ACHTUNG! Die Steckdose muß nabe bei
diesem Gerät angebracht und zugänglich sein.
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 let objects impede the operation of the
cooling fan on the rear panel.
R NEVER expose the transceiver to rain, snow or
any liquids.
R NEVER installing the transceiver in a place with-
out adequate ventilation. Heat dissipation may be af-
fected, and the transceiver may be damaged.
R NEVER operate or touch the transceiver with wet
hands. This may result in an electric shock or damage
the transceiver.
DO NOT the use of chemical agents such as benzine
or alcohol when cleaning, as they can damage the
transceiver’s surfaces.
DO NOT push the PTT when not actually desiring to
transmit.
AVOID using or placing the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
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.
BE CAREFUL! The top panel 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-7800 may dam-
age the transceiver.
The LCD display may have cosmetic imperfections that
appear as small or dark spots. This is not a malfunction
or defect, but a normal characteristic of LCD displays.
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.
Turn [I/O] switch (on the rear panel) OFF and/or dis-
connect the AC power cable from the AC outlet when
you will not use the transceiver for long period of time.
For U.S.A. only
CAUTION: Changes or modifications to this device,
not expressly approved by Icom Inc., could void your
