About the keypad microphone
Your radio may have a keypad microphone installed. The
keypad microphone has a PTT key as well as twelve alphanu-
meric keys, two scroll keys, and left and right selection keys.
The PTT key and the scroll and selection keys work in the
same way as those on the control head (see
“About the radio
controls” on page 21 ). The alphanumeric keys are used to
enter letters and numbers.
About the hand-held control head
Your radio may have a hand-held control head installed, to
enable you to operate the radio at a distance from the radio
body. The keys and controls work in the same way as those
on the standard control head and keypad microphone, with
the exception of the volume up and down keys. The hand-
held control head also has two additional function keys.
The hand-held control head may have been configured to
turn the radio on with a PTT press.
The hand-held control head keys and their functions are
summarized in the following diagram and table.
