PRECAUTIONS
RDANGER HIGH RF VOLTAGE! NEVER attach
an antenna or internal antenna connector during trans-
mission. This may result in an electrical shock or burn.
RWARNING! NEVER operate the transceiver with a
headset or other audio accessories at high volume levels.
Hearing experts advise against continuous high volume
operation. If you experience a ringing in your ears, reduce
the volume or discontinue use.
RWARNING! NEVER operate or touch the trans-
ceiver with wet hands. This may result in an electric
shock or damage to the transceiver.
RWARNING! NEVER apply AC power to the
[DC13.8V] socket on the transceiver rear panel. This
could cause a fire or damage the transceiver.
R WARNING! NEVER apply more than 16 V DC to the
[DC13.8V] socket on the transceiver rear panel, or use reverse
polarity. This could cause a fire or damage the transceiver.
RWARNING! NEVER let metal, wire or other objects
protrude into the transceiver or into connectors on the
rear panel. This may result in an electric shock.
RWARNING! ALWAYS use the supplied Black and
red cables with fuse holders. After connecting the fuse
holders,
NEVER cut the DC power cable between the
DC plug and fuse holder. If an incorrect connection is
made after cutting, the transceiver might be damaged.
RWARNING! Immediately turn OFF the transceiver
power and remove the power cable if it emits an abnor-
mal odor, sound or smoke. Contact your Icom dealer or
distributor for advice.
CAUTION: NEVER change the internal settings of the
transceiver. This may reduce transceiver performance
and/or damage to the transceiver.
In particular, incorrect settings for transmitter circuits,
such as output power, idling current, and so on, might
damage the expensive final devices.
The transceiver warranty does not cover any problems
caused by unauthorized internal adjustment.
CAUTION: NEVER install the transceiver in a place
without adequate ventilation. Heat dissipation may be
reduced, and the transceiver may be damaged.
DO NOT use or place the transceiver in direct sunlight
or in areas with temperatures below –30°C (+32°F) or
above +60°C (+122°F).
The basic operations, transmission and reception of the
transceiver are guaranteed within the specified operat-
ing temperature range. However, the LCD display may
not be operate correctly, or show an indication in the
case of long hours of operation, or after being placed in
extremely cold areas.
DO NOT use harsh solvents such as benzine or alco-
hol when cleaning, as they will damage the transceiver
surfaces.
DO NOT push the PTT switch when you don’t actually
desire to transmit.
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 inadvertent
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! The transceiver will become hot when
operating the transceiver continuously for long periods
of time.
USE only the specified microphone. Other manufactur-
ers’ microphones have different pin assignments, and
connection to the IC-F8100 may damage the transceiver
or microphone.
During mobile operation, NEVER place the transceiver
where air bag deployment may be obstructed.
During mobile operation, DO NOT place the transceiver
where hot or cold air blows directly onto it.
During mobile operation, DO NOT operate the trans-
ceiver without running the vehicle’s engine. When the
transceiver’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 engine. This will avoid possible damage to the
transceiver by ignition voltage spikes.
During maritime mobile operation, keep the trans-
ceiver and microphone as far away as possible from the
magnetic navigation compass to prevent erroneous indi-
cations.
Turn OFF the transceiver’s power and/or disconnect the
DC power cable when you will not use the transceiver
for long period of time.
KEEP the transceiver away from the heavy rain, and
Never immerse it in the water. The transceiver meets
IP54* requirements for dust-protection and splash resis-
tance.
However, once the transceiver has been dropped, dust-
protection and splash resistance cannot be guaranteed
due to the fact that the transceiver may be cracked, or
the waterproof seal damaged, and so on.
* Only when the supplied microphone is attached.

DAGC function
The AGC (auto gain control) controls receiver gain
to produce a constant audio output level even when
the received signal strength is varied by fading, and
so on.
