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:
•User awareness instructions should accompany the device when transferred to other users.
•Do not use this device if the operational requirements described herein are not met.
Operating Instructions (if applicable):
•Transmit no more than the rated duty factor of 50% of the time. To Transmit (Talk), push the Push
to Talk (PTT) button. To receive calls (listen), release the PTT button. Transmitting 50% of the time,
or less, is important because the radio generates measurable RF energy exposure only when
transmitting in terms of measuring for standards compliance.
•Transmit only when people outside the vehicle are at least the recommended minimum lateral
distance away from a properly installed according to installation instructions, externally mounted
antenna.
•When operating in front of the face, worn on the body, always place the radio in a Retevis
approved clip, holder, holster, case, or body harness for this product. Using approved body-worn
accessories is important because the use of Non-Retevis approved accessories may result in
exposure levels, which exceed the IEEE/ICNIRP RF exposure limits.
Hand-held Mode(if applicable)
• Hold the radio in a vertical position with the microphone (and other parts of the radio including the
antenna) at least 2.5 cm (one inch) away from the nose or lips. The antenna should be kept away
from the eyes. Keeping the radio at a proper distance is important as RF exposure decreases with
increasing distance from the antenna.
Phone Mode(if applicable)
•When placing or receiving a phone call, hold your radio product as you would a wireless
telephone. Speak directly into the microphone.
