Operating Instructions; Antenna - Retevis RT72 User Manual

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 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 regula-
tions, this separation distance will ensure that there is
sufficient distance from a properly installed external-
ly-mounted antenna to satisfy the RF exposure require-
ments.
•Occupational/Controlled Radio, this radio is designed for
and classified as "Occupational/Controlled 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/uncon-
trolled 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:
•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.
