RF Exposure Information(if applicable)
•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.
Push-to-Talk and
•Portable Device, this transmitter may operate with the antenna(s) documented in this filing in
body-worn configurations. RF exposure compliance is limited to the specific
belt-clip and accessory configurations as documented in this filing and the separation distance
between user and the device or its antenna shall be at least 2.5 cm.
•Mobile Device, during operation, the separation distance between user and the antenna subjects
to actual regulations, this separation distance will ensure that there is sufficient distance from a
properly installed externally-mounted antenna to satisfy the RF exposure requirements.
•Occupational/Controlled Radio, this radio is designed for and classified as "Occupational/Con-
trolled Use Only", meaning it must be used only during the course of employment by individuals
aware of the hazards, and the ways to minimize such hazards; NOT intended for use in a General
population/uncontrolled environment.
•General population/uncontrolled Radio, this radio is designed for and classified as "General
population/uncontrolled Use".
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.
NOTE: Nearly every electronic device is susceptible to electromagnetic interference
