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. The antenna should be kept away from eyes.
• When worn on the body, always place the radio in an EFJohnson Technologies
approved clip, holder, holster, case, or body harness for this product. Using approved
body-worn accessories is important because the use of EFJohnson Technologies 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
one inch (2.5 cm) 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 EFJohnson Technologies approved supplied or replacement antennas,
batteries, and accessories. Use of non-EFJohnson Technologies approved antennas,
batteries, and accessories may exceed the FCC RF exposure guidelines.
• For a list of EFJohnson Technologies approved accessories, see the service manual or
marketing accessory lists or contact the E.F. Johnson Company.
