RF Exposure Compliance and Control Guidelines and
Operating Instructions
To control your exposure and ensure compliance with the occupational/
controlled environment
exposure limits always adhere to the following procedures.
Guidelines:
• Do not remove the RF Exposure Label from the device.
• User awareness instructions should accompany device when
transferred to other users.
• Do not use this device if the operational requirements described
herein are not met.
Operating Instructions:
• Transmit no more than the rated duty factor of 50% of the time.

4
To transmit (talk), push the Push-To-Talk (PTT) button. To receive
calls, release the PTT button. Transmitting 50 % of the time, or
less, is important because this radio generates measurable RF
energy exposure only when transmitting (in terms of measuring for
standards compliance).
• Hold the radio in a vertical position in front of face with the
microphone (and the other parts of the radio, including the antenna)
at least one inch (2.5 cm) away from the nose. Keeping the radio at
the proper distance is important because RF exposures decrease with
distance from the antenna. Antenna should be kept away from eyes.
• When worn on the body, always place the radio in approved clip,
holder, holster, case, or body harness for this product. Use of non-
approved accessories may result in exposure levels, which exceed
the occupational/controlled environment RF exposure limits.
• Use only manufacturer’s approved supplied or replacement
antennas, batteries, and accessories. Use of non-manufacturer-
name approved antennas, batteries, and accessories may exceed
the FCC and IC RF exposure guidelines.
• For a list approved accessories please consult your local dealer for
information.

RF Radiation Information
1. This product is limited to occupational applications that can meet RF
energy radiation requirements. The user must be fully aware of the
RF radiation hazards and can take corresponding measures to meet
the RF radiation limitation requirements.
2. Radio frequency (RF) refers to the electromagnetic frequency that
can be radiated into space. It is a widely used technology in the
elds of communication, medical treatment, and food processing. It
will generate certain RF radiation during use.
EXPOSURE RF compliance et Lignes de
contrôle et Instructions opérationnelles
contrôle et Instructions opérationnelles
Pour contrôler votre exposition et garantir le respect des limites
d'exposition dans un environnement professionnel / contrôlé, suivez
toujours les procédures suivantes.
Des lignes directrices:
• Ne retirez pas l'étiquette d'exposition RF de l'appareil.
• Les instructions de sensibilisation des utilisateurs doivent
accompagner l'appareil lors de leur transfert à d'autres utilisateurs.
• N'utilisez pas cet appareil si les exigences opérationnelles décrites ici
ne sont pas remplies.
Mode d'emploi:
• Ne transmet pas plus que le facteur de marche nominal de 50%
du temps. Pour transmettre (parler), appuyez sur le bouton Push-
To-Talk (PTT). Pour recevoir des appels, relâchez le bouton PTT.
La transmission 50% du temps, ou moins, est importante car cette
radio génère une exposition mesurable à l'énergie RF uniquement
lors de la transmission (en termes de mesure pour la conformité aux
normes).

• Tenez la radio en position verticale devant le visage avec le microphone
(et les autres parties de la radio, y compris l'antenne) à au moins 2,5
cm du nez. Garder la radio à la bonne distance est important car les
expositions RF diminuent avec la distance de l'antenne. L'antenne doit
être tenue à l'écart des yeux.
• Lorsqu'elle est portée sur le corps, placez toujours la radio dans un clip,
un support, un étui, un étui ou un harnais de sécurité approuvés pour
ce produit. L'utilisation d'accessoires non approuvés peut entraîner des
niveaux d'exposition qui dépassent les limites d'exposition aux RF de
l'environnement professionnel / contrôlé.
