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.

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 Bridge Source Selector is pressed too soon, video playback from the iPod will not be available.

Memory

If the AVR 760/AVR 660 is unplugged or experiences a power outage, it will retain user settings for up to four weeks.
