EXPLICIT DEFINITIONS
WORD DEFINITION
RDANGER! Personal death, serious injury or

CAUTION Equipment damage may occur.
NOTE
Recommended for optimum use.
No risk of personal injury, fire or
electric shock.

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, etc., 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, etc.
* Only when the supplied microphone is attached.

ïPreamp and Attenuator
The preamp amplifies received signals in the front
end circuit to improve the S/N ratio and sensitivity.
Turn this function ON when receiving weak signals.
The attenuator prevents a strong undesired signal
near the desired frequency or near your location,
such as from a broadcast station, from causing dis-
tortion or spurious signals.

ïNoise Blanker
The noise blanker reduces pulse-type noise such as
that generated by automobile ignition systems.
The noise blanker may distort reception of strong

■Functions for receive (Continued)
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, etc.
The transceiver has two AGC characteristics (time
constant: FAST and SLOW) and AUTO.

DAGC OFF function
When receiving weak signals with adjacent strong
signals or noise, the AGC function may reduce the
sensitivity. In this situation, the AGC function should
be deactivated.

SELCALL/ALE OPERATION
2001 NEW
■Selcall or ALE
The Selcall uses a 4 or 6-digit address (ID) and allows
you to make an individual/group call. The ALE (auto-
matic link establishment) is a system which automati-
cally selects an available frequency and establishes a
communication link. The IC-F8100 ALE system com-
piles with basic requirements MIL-STD 188-141-B
(Appendix A).
The selcall or ALE features are not available, de-
pending on the preprogramming. Check the selcall
or ALE capabilities in the Admin Menu, and then set
the settings to RX&TX.
ïAvailable calls
• Selective call
The Selective call allows you to make an individual/
group call using an individual ID (identification) as-
signed for each transceiver.
• Phone call
Allows you to make a Phone call through a telephone
interconnect service provider.
• Message call
Allows you to exchange up to 64 character* text mes-
sages with the intended ID station.
* 64 character for ICOM Selcall system; 32 character
for Open Selcall system.
• Send Position call
Allows you to send your own position information to
the intended ID station.
• Get Position call
The Get Position call allows you to request the in-
tended ID station to send position information.
• Get Status call
Requests to send radio status information including
power supply voltage, signal strength, output power,
VSWR, etc.
• Emergency call
Allows you to broadcast an emergency signal with own
position information.
•The Phone call, Message call, Send Position call,
Get Position call, Get Status call and Emergency
call use Icom original commands, these calls may
not be compatible with other brands. (Icom Selcall
system)
•Dependingonthepreprogramming,youcanselect
the Open Selcall system* for these call except the
Get Status call.
* Open Selcall system is compatible with other brands.
Ask your dealer for details.
• Channel Test call
The Channel Test call allows the user determine the
signal quality between your transceiver and specific
transceiver before an individual/group call.
• ALE individual/net call
Automatically establish a communication link by using
the ALE table.
• ALE sounding
Automatically sends a sounding signal at a certain
interval (0.5–16 hours) to check the propagation
and stores the data in a table. Also available manual
sounding.
• ALE AMD (Automatic Message Display)
Automatically sends and receives up to a 90 character
text message.
