RF Exposure Compliance and Control Guidelines and Operating Instructions
•General population/uncontrolled Radio, this radio is designed for and classified as “General population/uncon-
trolled Use”.
To control your exposure and ensure compliance with the occupational/controlled environment exposure limits,
always adhere to the following procedures. 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.
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 necessary information or less, is important
because the radio generates measurable RF energy exposure only when transmitting in terms of measuring for
standards compliance.
•DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may also
cause you to exceed 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, and the antenna
gain shall not exceed the specified gain by the manufacturer declared.
•DO NOT transmit for more than 50% of total radio use time, more than 50% of the time can cause RF exposure
compliance requirements to be exceeded.
•During transmissions, your 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.
•Portable Device, this transmitter may operate with the antenna(s) documented in this filing in Push-to-Talk and
body-worn configurations. RF exposure compliance is limited to the specific belt-clip and accessory configura-
tions as documented in this filing and the separation distance between head and the device or its antenna shall
be at least 2.5 cm.
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.
