Keypad Microphones

Installation Instructions

 

Introduction

The T02-00005-ABAA and T02-00005-ABBA 
keypad microphones plug 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.

The T02-00005-ABAA and T02-00005-
ABBA keypad microphones can also be used 
with TM8100 analog radios for channel 
selection and DTMF calls.

The T02-00005-ABBA keypad microphone 
has a longer 10ft (3m) cable.

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

If an incorrect character has been dialed, use the left selection key on either the microphone 
keypad or control head to clear it and move back one character.

Dialing Text Messages

When the keypad microphone is used to enter a text message, the microphone keys have 
special functions. Use the 

 key to toggle between upper and lower case characters and 

use the left selection key 

 to delete a character from the display.
