Additional information on troubleshooting possible problems with your AVR 160, or installation-related issues, may be found in the list of “Frequently Asked Questions”, which is located in the Product Support section at www.harmankardon.com.

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 160, place it in Standby mode (press the front-panel Standby/On Switch so that the Power Indicator turns amber). Then press the front-panel Surr. Mode Button 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.

Memory

If the AVR 160 is unplugged or experiences a power outage, it will retain user settings for up to two weeks.
