TROUBLESHOOTING GUIDE
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 460/AVR 360, place it in Standby mode (press the front-
panel Standby/On Switch so that the Power Indicator turns amber). Then
press the front-panel OK Button for at least 5 seconds until the RESET
message appears.
If the receiver does not function correctly after a processor reset, contact an
authorized Harman Kardon service center for assistance. Authorized service
centers may be located by visiting the Web site at www.harmankardon.com.
NOTE : After performing a system reset, wait at least 1 minute before
pressing any Source Selectors.
