Master Reset
The radio has a reset feature that allows you to return
certain settings back to the factory default settings.
Use this feature when adjustments have been made that
affect the sound quality or operation of the radio and
you are unsure of how to return to the original settings.
This master reset feature will reset the following:
• Bass, Treble, Fade, and Balance
• Confirmation beeps to on
• SDV to setting 2
• DDL to on
• EQ to off.
To perform the master reset, do the following:
1. Turn off the radio by pressing the OFF button.
2. Press the ON button and pushbutton 4 at the same
time for about two seconds.
After the radio has finished resetting, the radio will
turn on with the original settings and no message
will appear on the display.
