TMAA02-08 Keypad Microphone
Installation Instructions
Introduction
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 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.
Operation
Dialing Characters
