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 7550HD, 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 7550HD is unplugged or experiences a power outage, it
will retain user settings for up to four weeks.
