SAFETY TRAINING INFORMATION
WARNING
Your Icom radio generates RF electro-
magnetic energy during transmit mode.
This radio is designed for and classi-
fied as “Occupational Use Only,” mean-
ing 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 uncon-
trolled environment.
• For compliance with FCC and IC RF Exposure Re-
quirements, the transmitter antenna installation shall
comply with the following three conditions:
1. The transmitter antenna gain shall not exceed 0
dBi.
2. IC-FR5000:
Transmit only when people are at least the rec-
ommended minimum distance of 141 centimeters
away from the properly installed antenna. This
separation distance will ensure that there is suf-
ficient distance from a properly installed external-
ly-mounted antenna to satisfy the RF exposure
requirements in the applicable RF exposure com-
pliance standards.
2. IC-FR6000/IC-FR6000-L:
Transmit only when people are at least the rec-
ommended minimum distance of 122 centimeters
away from the properly installed antenna. This
separation distance will ensure that there is suf-
ficient distance from a properly installed external-
ly-mounted antenna to satisfy the RF exposure
requirements in the applicable RF exposure com-
pliance standards.
CAUTION
To ensure that your exposure to RF
electromagnetic energy is within the
FCC and IC allowable limits for occu-
pational use, always adhere to the fol-
lowing 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 specifically
authorized by the manufacturer for use with this ra-
dio.
• 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 indicator” lights red.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 hospitals, aircraft,
and blasting sites.

SAFETY TRAINING INFORMATION
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.
• An 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 condi-
tions suivantes:
1. Le gain de l’antenne du radio émetteur ne doit pas
dépasser 0 dBi.
2. IC-FR5000:

la distance minimale recommandée de 141 cen-
timètres de l'antenne est correctement installé.
Cette distance de sécurité assurera que les per-
sonnes soient placées suffisamment loin d’une
antenne correctement fixée à l’extérieur pour sat-
isfaire aux exigences en matière d’exposition aux
RF, en vertu des normes de conformité applica-
bles.
2. IC-FR6000/IC-FR6000-L:
Transmettre que lorsque les gens sont au moins
la distance minimale recommandée de 122 cen-
timètres de l'antenne est correctement installé.
Cette distance de sécurité assurera que les per-
sonnes soient placées suffisamment loin d’une
antenne correctement fixée à l’extérieur pour satis-
faire aux exigences 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 exposition
aux RF supérieure aux limites établies par la FCC
et d’IC. Lorsque le voyant DEL rouge s’allume,
cette radio est en train d’émettre. 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 hôpitaux,
les aéronefs et les sites de dynamitage.
