4.5 MICROPHONE MOUNTING
For proper operation of monitor modes, a microphone hanger clip must be used.
Mount the microphone hanger clip securely to the desired location. The KNG
mobile microphones have a self grounding hang-up button. No grounding is
required for the hang-up clip.
Drill 1/4” pilot holes through the mounting plate. A mounting template can 1.
be found on page 15 or use the hang-up clip as a template. Make sure the
holes are free from the metal fl ashing.
Fasten the mounting bracket to the chassis using self tapping screws.2.
To connect the microphone to the radio:

Gently slide the connector onto the radio’s microphone jack.2.
DO NOT FORCE. EXCESS PRESSURE COULD DAMAGE THE
MICROPHONE.
Tighten the connection by screwing the microphone connector sleeve in a 3.
clockwise direction.
