KNOB
Applies power to the radio and ad-

the control clockwise out of detent
applies power to the radio. A single
alert tone sounds (if enabled through
programming) to indicate the radio is
operational.
Rotating the control clockwise in-
creases the volume level. Minimum
volume levels may be programmed
into the radio to prevent missed calls
due to a low volume setting. While
adjusting the volume the display will
momentarily indicate the volume
level (i.e.
VOL = 3 1). The volume
range is from a minimum pro-
grammed level of zero (displayed as
OFF in the display) up to 31 which is
the loudest level.
