INSTALLATION:
1. Turn the radio off.
Note: Installation of the headset while the radio is on
may cause the radio to transmit constantly, locking up
your radio system. To correct this should it happen,
turn off the radio. The radio can then be turned back
on, restoring normal operations.
2. Remove any dust caps or covers from radio
accessory connector.
3. Attach headset to the radio connector.
4. Tighten mounting thumbscrews if required.
OPERATION:
Turn the radio on and operate it as explained in the operating
instructions supplied with the radio. Installing the headset
bypasses the radio’s speaker and routes the output to the
headset’s speaker. The in-line push-to-talk (PTT) switch disables
the radio’s microphone and enables the boom microphone.
(1) Microphone position is adjusted by moving arms (X), (Y) and
(Z) to place the microphone within 1/2” of the front and toward
the side of the mouth. The position can be secured or loosened
by adjusting thumbscrews (A) and screw (B). The position can
also be rotated from right to left ear by rotating upwards.
(2) For over-the-head models, earcup position is adjusted by
sliding the earcup (S) up or down the overhead band (T). The
position can be secured or loosened by adjusting nuts (C).
(3) For behind-the-head models, earcup position is adjusted by
pulling the two overhead straps (W) apart and pressing them
back together at the desired position.
