About your radio
Basic operation
The radio controls are the PTT key, power/volume
control, channel selector, three-way selector control,
scroll keys, selection keys, and function keys. Some keys
have functions assigned to both short and long key
presses:
■ a short key press is less than one second, and
■ a long key press is more than one second
The radio controls and their functions are described in
the following sections.
Turning your radio on/off
Turn the power/volume control switch clockwise to turn
on the radio. Turn the switch counterclockwise to turn
the radio off.
Note: Your radio will automatically power-down if
there is insufficient charge in the battery.
Adjusting the volume
Rotate the power/volume control clockwise to increase
the speaker volume and counterclockwise to decrease
the volume.
Note: The volume control also changes the volume
level of the radio’s audible indicators.
About the channel selector

channels. When the radio is first switched on, the
channel that is acquired is the one indicated by the
current position of the channel selector switch.
