TROUBLESHOOTING GUIDE

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.

If the AVR 460/AVR 360 is unplugged or experiences a power outage, it will 
retain user settings for up to two weeks.
