Support section of our Web site: www.harmankardon.com
Resetting the Remote
To reset the remote to its factory-default condition, simultaneously press and hold any
Source Selector button and the "0" Number button. When the Program Indicator LED
flashes amber, enter the code "333." When the green LED goes out, the remote control
will be reset.
Processor Reset
If the AVR behaves erratically after a power surge, first turn off the rear-panel Main Power
switch and unplug the AC power cord for at least 3 minutes. Plug the cord back in and
turn the AVR on. If this procedure doesn't help, reset the AVR's processor as described
below.
NOTE: A processor 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's processor:
1. Press the front-panel Standby/On switch to place the unit in the Standby mode (the
Power Indicator LED will turn amber).
2. Press and hold the front-panel Surround Mode button for at least 5 seconds until the
RESET message appears on the front-panel Message display.
