proceSSor reSet
If the unit behaves erratically after a power surge, first turn off the Main
Power Switch and unplug the AC power cord for at least 3 minutes. Plug the
cord back in and turn the receiver on. If this doesn't help, reset the AVR.
NOTE: A system reset erases all user configurations, including video
resolution, speaker and level settings, and tuner presets. After a reset,
reenter all of these settings from your notes in the appendix worksheets.
To reset the AVR 760/AVR 660, place it in Standby mode (press the front-
panel Standby/On Switch so that the Power Indicator turns amber). Then
press the front-panel AVR Settings and Source List Buttons simultaneously
until the RESET message appears.
