 When transmitting, hold the radio in a vertical position with its microphone 1 inch (2.5 cm) away from your
mouth and keep the antenna at least 1 inch (2.5 cm) away from your head.
 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, release the PTT button. The PTT button may reside on the radio itself or may be hosted
on approved accessories. Transmitting 50% of the time, or less, is important because this radio generates mea-
surable RF energy exposure only when transmitting (in terms of measuring for standards compliance).
The radio is transmitting when the red (analog mode) or blue (digital mode) LED on the top of the radio is illu-
minated. You can cause the radio to transmit by pressing the P-T-T button.
 In front of the face. Hold the radio in a vertical position with the microphone (and other parts of the radio in-
cluding the antenna) at least 1 inch (2.5 cm) away from the nose or lips. Keeping the radio at a proper distance is
important to ensure compliance.
 Body Worn Operation: When worn on the body, always place the radio in a Vertex Standard approved clip, hold-
er, holster, case, or body harness for this product. Using approved body-worn accessories is important because
the use of non-Vertex Standard approved accessories may result in exposure levels, which exceed the occupation-
al/controlled environment RF exposure limits.
 Always use Vertex Standard authorized accessories.
 The information listed above provides the user with the information needed to make him or her aware of RF ex-
posure, and what to do to assure that this radio operates with the FCC RF exposure limits of this radio.
 Electromagnetic Interference/Compatibility
During transmissions, this 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, health
care facilities, aircraft, and blasting sites.
