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.
23.2 Radio Programming
The radio does not need to be programmed to recognize the presence of a
keypad microphone, as this is automatically done when the radio is
powered on. However, there are a a number of related fields that should be
configured, to enable the keypad microphone to be used effectively.
Refer to the online help of the programming application for more
information about the programming options.
Note
You must power-cycle the radio after replacing the keypad micro-
phone with a programming lead, in order to read or program
the radio.
