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 IC RF Exposure Re-
quirements, the transmitter antenna installation shall
comply with the following two conditions:
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 90 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 90 cen-
timeters separation distance. In order to ensure
this distance is met, the installation of the antenna
must be mounted at least 90 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
200 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 ex-
posure requirements in the applicable RF expo-
sure compliance standards.
CAUTION
To ensure that your exposure to RF
electromagnetic energy is within the
FCC and IC allowable limits for occupa-
tional use, always adhere to the follow-
ing 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 and IC RF exposure
limits. A proper antenna is the antenna supplied with
this radio by the manufacturer or an antenna specifi-
cally authorized 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 and IC RF exposure
compliance requirements to be exceeded. The radio
is transmitting 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.

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’IC
en matière d’exposition aux RF, il est nécessaire
que l’antenne soit installée conformément aux trois
conditions suivantes:
1. Le gain de l’antenne du radio émetteur ne doit
pas dépasser 0 dBi.
2. Il faut que l’antenne émettrice de cet appareil
soit placée à l’extérieur d’un véhicule et tenue
éloignée d’au moins 90 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 90
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 200 cm de
l’antenne correctement installée. Cette distance
de sécurité assurera que les personnes soient
placées suffisamment loin d’une antenne correc-
tement fixée à l’extérieur pour satisfaire aux exi-
gences 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 et d’IC pour une
utilisation grand public, veuillez en
tout temps respecter les directives
suivantes:
• 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 et d’IC .
L’antenne 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 et d’IC. La radio est en train d’émettre lors-
que 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.

PRECAUTIONS
RDANGER HIGH RF VOLTAGE! NEVER attach an
antenna or internal antenna connector during transmis-
sion. This may result in an electrical shock or burn.
RDANGER! NEVER operate the transceiver near
unshielded electrical blasting caps or in an explosive
atmosphere. This could cause an explosion and death.
RWARNING! NEVER operate the transceiver with
a headset or other audio accessories at high volume
levels. If you experience a ringing in your ears, reduce
the volume or discontinue use.
RWARNING! NEVER operate or touch the transceiver
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.
RWARNING! NEVER apply more than 16 V DC to the
[DC13.8V] socket on the transceiver rear panel. This
could cause a fire or damage the transceiver.
RWARNING! NEVER reverse the DC power cable
polarity. This could cause a fire or damage the trans-
ceiver.
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 hold-
ers, 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.
RWARNING! NEVER operate the transceiver during a
lightning storm. It may result in an electric shock, cause
a fire or damage the transceiver. Always disconnect the
power source and antenna before a storm.
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-F8101 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.
