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 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.
