ADVANCED FUNCTIONS
TV Button re-lights, enter the code “333”. When the TV Button goes
out, and all of the Source Selectors flash, the remote will be reset.
Processor Reset
If the unit behaves erratically after a power surge, first turn off the Master
Power Switch and unplug the AC power cord for at least three minutes.
Plug the cord back in and turn the receiver on. If this doesn’t help, reset
the AVR.
NOTES:
• 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.
• The RS-232 Reset Button on the rear panel of the
AVR 3550HD does not perform a system reset. DO NOT
press the RS-232 Reset Button.
To reset the AVR 3550HD, place it in Standby mode (press the front-
panel Standby/On Switch so that the Power Indicator turns amber).
Then press and hold the front-panel OK Button for at least five 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.
Memory
If the AVR 3550HD is unplugged or experiences a power outage, it will
retain user settings for up to four weeks.
