About the keypad microphone
Your radio may have a keypad microphone installed. The
keypad microphone has a PTT key as well as twelve
alphanumeric keys, two scroll keys, and shift and clear keys.
The keypad microphone cannot be used to dial DTMF (Dual-
tone Multi-frequency) calls. DTMF calls can only be made if
programmed as a preset call (see "Making a preset call" on
page 34).
The PTT key, and the scroll, clear and shift keys work in the
same way as those on the control head (see "About the
radio controls" on page 19). The alphanumeric keys are used
to enter numbers 0—9, and .
Dialling in MPT trunked mode
The alphanumeric keys can be used in trunked mode to
directly dial any number you can dial using the shift key and
scroll keys. In addition, you may be able to access special
MPT trunking functions using the and keys.
The availability of these functions is dependant on the way
your radio is programmed and the way your network operates.
