23 TMAA02-08 Keypad Microphone
The TMAA02-08 keypad microphone plugs into the
microphone socket on the radio control head, and enables
users to make calls to other radios, groups, or to a PABX or
PSTN. The types of call that you can make depends on the
radio model and the way it has been programmed.
The microphone button operates a hookswitch, which is
closed when the microphone is connected to the microphone
clip, and open when the microphone is removed from the
microphone clip. The function of the hookswitch is
determined by the way the radio is programmed.
As well as the PTT key, there are twelve alphanumeric keys.
The functions of the other keys depend on the radio model,
as follows:

Important
The keypad microphone grommet must be installed 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.
