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 few related fields that should be
configured, as required, to enable the keypad microphone to be
used effectively.
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.
Set the Control Head Mic Gain to Low.
In conventional mode, there are check boxes labelled Selcall Call Dialling,
DTMF Call Dialling and Phone Patch Call Dialling. There is also an
option Conventional Dialling Type field, where you can program the
radio to dial labels or channels from the default display.
Refer to the online help of the programming application for more information
about these programming options.
In MPT1327 trunked mode, there may be check boxes labelled DTMF
Dialling, PABX Calls and PSTN Calls. These check boxes need to be
selected before you can make these types of calls.
Refer to the online help of the programming application for more information
about these programming options.
The following table and diagram summarizes the signals used for the keypad
microphone on the radio's microphone connector and shows the interface
between the keypad microphone and the radio.
