PRECAUTIONS
R
DANGER HIGH RF VOLTAGE! NEVER
attach an antenna or internal antenna connector
during transmission. This may result in an electrical
shock or burn.
R
WARNING! NEVER
operate the transceiver
with a headset or other audio accessories at high vol-
ume levels. Hearing experts advise against continu
-
ous high volume operation. If you experience a ringing
in your ears, reduce the volume or discontinue use.
R
WARNING!
NEVER
operate or touch the
transceiver with wet hands. This may result in an elec-
tric shock or damage to the transceiver.
R
WARNING!
NEVER
let metal, wire or other ob-
jects protrude into the transceiver or into connectors
on the rear panel. This may result in an electric shock.
R
WARNING!
Immediately turn the transceiver
power OFF and remove the power cable if it emits an
abnormal odor, sound or smoke. Contact your Icom
dealer or distributor for advice.
CAUTION: NEVER
put the transceiver in any un-
stable place (such as on a slanted surface or vibrated
place). This may cause injury and/or damage to the
transceiver.
CAUTION: NEVER
put the transceiver’s rear
panel side down after lifting up the transceiver by
holding rack mounting handle. This may scratch the
surface of the place or damage the connectors on the
transceiver’s rear panel.
CAUTION:
NEVER
change the internal settings
of the transceiver. This may reduce transceiver per-
formance and/or damage to the transceiver.
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 prob-
lems caused by unauthorized internal adjustment.
CAUTION:
NEVER
block any cooling vents on the
top, rear or bottom of the transceiver.
CAUTION:
NEVER
expose the transceiver to rain,
snow or any liquids.
CAUTION:
NEVER
install the transceiver in a
place without adequate ventilation. Heat dissipation
may be reduced, and the transceiver may be dam-
aged.
CAUTION:
The transceiver weighs approximately
22.5 kg (50 lb). Always have two people available to
carry, lift or turn over the transceiver.
CAUTION:
The line-voltage receptacle must be
near the transceiver and must be easily accessible.
Avoid extension cords.
DO NOT
use harsh solvents such as benzine or al-
cohol when cleaning, as they can damage the trans-
ceiver’s surfaces.
DO NOT
push the PTT switch when you don’t actu-
ally desire to transmit.
DO NOT
use or store the transceiver in areas with
temperatures below ±0°C (+32°F) or above +50°C
(+122°F).
DO NOT
place the transceiver in excessively dusty
environments or in direct sunlight.
DO NOT
place the transceiver against walls or
putting anything on top of the transceiver. This may
overheat the transceiver.
Always place unit in a secure place to avoid inadvert-
ent use by children.
BE CAREFUL!
If you use a linear amplifier, set the
transceiver’s RF output power to less than the linear
amplifier’s maximum input level, otherwise, the linear
amplifier will be damaged.
BE CAREFUL!
touch the transceiver top cover when
transmitting continuously for long periods of time. The
top cover may be hot.
Use Icom microphones only (supplied or optional).
Other manufacturers’ microphones have different pin
assignments, and connection to the IC-7700 may
damage the transceiver or microphone.
The LCD display may have cosmetic imperfections
that appear as small dark or light spots. This is not a
malfunction or defect, but a normal characteristic of
LCD displays.
During maritime mobile operation, keep the trans-
ceiver and microphone as far away as possible from
the magnetic navigation compass to prevent errone-
ous indications.
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
authority to operate this device under FCC regula-
tions.
