23.2 Installation
Installing the
Microphone
Important
The keypad microphone grommet must be installed when-
ever the microphone is plugged into the microphone
socket. When installed, the grommet has two functions:
■
to prevent damage to the microphone socket when
there is movement of the microphone cord, and
■
to ensure that the control head is sealed against water,
dust and other environmental hazards.
1. Make sure the radio is turned off, then plug the keypad microphone
cord into the microphone socket on the radio control head.
Important
The radio will only recognize the presence of the keypad
microphone when the radio is powered on, so that if the
microphone is plugged in after the radio has been powered
on, it will not recognize the keypad microphone. Also, if
the keypad microphone is plugged in on power up but is
later unplugged, then plugged back in, the radio will not
recognize it again until the next power cycle.
2. Slide the microphone grommet along the microphone cord and push
two adjacent corners of the grommet into the microphone
socket cavity.
3. Squeeze the grommet and push the remaining corners into position.
4. Check that the grommet is seated correctly in the cavity.
Installing the
Microphone Clip
Install the microphone clip in the most convenient location for the radio
user. It must be within easy reach of the user, but in such a position that the
microphone PTT key cannot be inadvertently activated or jammed on.
