Adjusting the Volume
Your radio is preprogrammed to reset to medium volume rate,
which is Level 12, by default whenever the radio powers up.
To increase the volume, turn the
MFK
clockwise. The display
shows volume bars and volume level when you change the
volume.
Note:
If
Volume Change
is secondary feature of the knob,
see
Multi Function Knob (MFK)
on page 15 to toggle
the function of the knob.
To decrease the volume, turn this MFK counterclockwise.
Note:
Ensure that the main speaker is pointed towards you
for increased loudness and intelligibility, especially in
areas with loud background noises.
