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 (–22°F) or
above +60°C (+140°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.

SAFETY TRAINING INFORMATION
WARNING
Your Icom radio generates RF electromag-
netic energy during transmit mode. This
radio is designed for and classified as “Oc-
cupational Use Only”, meaning it must be
used only during the course of employment
by individuals aware of the hazards, and the ways to
minimize such hazards. This radio is NOT intended for
use by the “General Population” in an uncontrolled en-
vironment.
• For compliance with FCC and Industry Canada RF
Exposure Requirements, the transmitter antenna in-
stallation shall comply with the following two condi-
tions:
1.The transmitter antenna gain shall not exceed
0 dBi.
2. The antenna is required to be located outside of
a vehicle and kept at a distance of 80 centime-
ters or more between the transmitting antenna of
this device and any persons during operation. For
small vehicle as worst case, the antenna shall be
located on the roof top at any place on the centre
line along the vehicle in order to achieve 80 cen-
timeters separation distance. In order to ensure
this distance is met, the installation of the antenna
must be mounted at least 80 centimeters away
from the nearest edge of the vehicle in order to
protect against exposure to bystanders.
3. Transmit only when people outside the vehicle are
at least the recommended minimum distance of
160 centimeters away from the properly installed
antenna. This separation distance will ensure that
there is sufficient distance from a properly installed
externally-mounted antenna to satisfy the RF expo-
sure requirements in the applicable RF exposure
compliance standards.
CAUTION
To ensure that your exposure to RF
electromagnetic energy is within the
FCC allowable limits for occupational
use, always adhere to the following
guidelines:
• DO NOT operate the radio without a proper antenna
attached, as this may damage the radio and may
also cause you to exceed FCC RF exposure limits. A
proper antenna is the antenna supplied with this radio
by the manufacturer or an antenna specifically autho-
rized by the manufacturer for use with this radio.
• DO NOT transmit for more than 50% of total radio use
time (“50% duty cycle”). Transmitting more than 50%
of the time can cause FCC RF exposure compliance
requirements to be exceeded. The radio is transmit-
ting when the “TX” icon is displayed. You can cause
the radio to transmit by pressing the “PTT” switch.
Electromagnetic Interference/Compatibility
During transmissions, your Icom radio generates RF
energy that can possibly cause interference with other
devices or systems. To avoid such interference, turn
OFF the radio in areas where signs are posted to do
so. DO NOT operate the transmitter in areas that are
sensitive to electromagnetic radiation such as hospi-
tals, aircraft, and blasting sites.
FCC INFORMATION
• FOR CLASS A UNINTENTIONAL RADIATORS:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15
of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference in which case the user will be required to correct the interference at his own expense.
CAUTION: Changes or modifications to this trans-
ceiver, not expressly approved by Icom Inc., could
void your authority to operate this transceiver under
FCC regulations.

INFORMATION EN MATIÈRE DE SÉCURITÉ
AVERTISSEMENT
Votre radio Icom produit une énergie
électromagnétique de radiofréquen-
ces (RF), en mode de transmission.
Cette radio est conçue pour un
«usage professionnel seulement» et
classée comme tel, ce qui signifie qu’elle doit être
utilisée uniquement dans le cadre d’un travail par
des personnes conscientes des dangers et des
mesures visant à minimiser ces dangers. Elle
N’EST PAS conçue pour une «utilisation grand
public», dans un environnement non contrôlé.
• Afin de satisfaire aux exigences de la FCC et d’In-
dustrie Canada en matière d’exposition aux RF, il
est nécessaire que l’antenne soit installée confor-
mément aux trois conditions suivantes:
1. Le gain de l’antenne du radio émetteur ne doit
pas dépasser 0dBi.
2. Il faut que l’antenne émettrice de cet appareil
soit placée à l’extérieur d’un véhicule et tenue
éloignée d’au moins 80 centimètres de toute per-
sonne pendant le fonctionnement. Dans le pire
des cas, pour un petit véhicule, l’antenne doit être
placée sur le toit, n’importe où dans l’axe central
du véhicule, afin de respecter une distance de 80
cm du bord le plus rapproché du véhicule et ainsi
éviter que les personnes présentes soient expo-
sées.
3. Émettre uniquement lorsque les personnes à
l’extérieur du véhicule se trouvent à au moins la
distance minimale recommandée de 160 cm de
l’antenne correctement installée. Cette distance
de sécurité assurera que les personnes soient
placées suffisamment loin d’une antenne correcte-
ment fixée à l’extérieur pour satisfaire aux exigen-
ces en matière d’exposition aux RF, en vertu des
normes de conformité applicables.
MISE EN GARDE
Afin de vous assurer que votre expo-
sition à une énergie électromagnéti-
que de RF se situe dans les limites
permises par la FCC pour une utili-
sation grand public, veuillez en tout
temps respecter les directives sui-
vantes:
• NE PAS faire fonctionner la radio sans qu’une
antenne appropriée y soit fixée, car ceci risque
d’endommager la radio et causer une exposition
supérieure aux limites établies par la FCC. L’an-
tenne appropriée est celle qui est fournie avec
cette radio par le fabricant ou une antenne spécia-
lement autorisée par le fabricant pour être utilisée
avec cette radio.
• NE PAS émettre pendant plus de 50 % du temps
total d’utilisation de l’appareil («50 % du facteur
d’utilisation»). Émettre pendant plus de 50 % du
temps total d’utilisation peut causer une exposi-
tion aux RF supérieure aux limites établies par
la FCC. La radio est en train d’émettre lorsque
le témoin du mode de transmission s’affiche sur
l’écran ACL. La radio émettra si vous appuyez sur
le bouton du microphone.
Interférence électromagnétique et compatibilité
En mode de transmission, votre radio Icom produit de
l’énergie de RF qui peut provoquer des interférences
avec d’autres appareils ou systèmes. Pour éviter de
telles interférences, mettez la radio hors tension dans
les secteurs où une signalisation l’exige. NE PAS faire
fonctionner l’émetteur dans des secteurs sensibles
au rayonnement électromagnétique tels que les hôpi-
taux, les aéronefs et les sites de dynamitage.
