Hytera PD79X Ex Manual page 6

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, release the PTT button. Transmitting 50 % of the
time, or less, is important because this radio generates measurable RF energy exposure only when
transmitting (in terms of measuring for standards compliance).
• Hold the radio in a vertical position in front of face with the microphone (and the other parts of
the radio, including the antenna) at least one inch (2.5 cm) away from the nose. Keeping the
radio at the proper distance is important because RF exposures decrease with distance from the
antenna. Antenna should be kept away from eyes.
• When worn on the body, always place the radio in a Hytera's approved clip, holder, holster, case,
or body harness for this product. Using approved body-worn accessories is important because the
use of Hytera's or other manufacturer's non-approved accessories may result in exposure levels,
which exceed the FCC's occupational/controlled environment RF exposure limits.
• If you are not using a body-worn accessory and are not using the radio in the intended use
position in front of the face, then ensure the antenna and the radio are kept at least 2.5 cm (one
inch) from the body when transmitting. Keeping the radio at the proper distance is important
because RF exposures decrease with increasing distance from the antenna.
• Use only manufacturer's name approved supplied or replacement antennas, batteries, and
accessories. Use of non-manufacturer-name approved antennas, batteries, and accessories may
exceed the FCC RF exposure guidelines.
• For a list of Hytera's approved accessories (see the user manual), or (visit the following website
