SAFETY TRAINING INFORMATION
WARNING
Your Icom radio generates RF electro-
magnetic energy during transmit
mode. This radio is designed for and
classified as “Occupational Use Only,”
meaning it must be used only during
the course of employment by individu-
als 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-FR5300/UR-FR5300:
Transmit only when people are at least the recom-
mended minimum distance of 60 centimeters away
from the properly installed antenna. This separa-
tion distance will ensure that there is sufficient dis-
tance from a properly installed externally-mounted
antenna to satisfy the RF exposure requirements
in the applicable RF exposure compliance stan-
dards.
2. IC-FR6300/UR-FR6300:
Transmit only when people are at least the recom-
mended minimum distance of 50 centimeters away
from the properly installed antenna. This separa-
tion distance will ensure that there is sufficient dis-
tance from a properly installed externally-mounted
antenna to satisfy the RF exposure requirements
in the applicable RF exposure compliance stan-
dards.
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 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 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.

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-FR6300/UR-FR6300:
Transmettre que lorsque les gens sont au moins
la distance minimale recommandée de 50 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

sition à une énergie électromagné-
tique 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.
