23 TMAA02-08 Keypad Microphone
The TMAA02-08 keypad microphone plugs into the
microphone socket on the graphical-display 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 way your radio has been programmed.
As well as the PTT key, there are twelve alphanumeric keys,
two scroll keys, and a left and right selection key on the keypad
microphone. The selection keys and scroll keys duplicate the
keys on the control head and the 12 alphanumeric keys on the
keypad microphone are used to dial call strings and enter text.
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.
