Learning
If you have programmed a product’s codes into the remote and find that
some functions are missing, the AVR 3550HD remote may “learn” indi-
vidual codes if you have the product’s original remote. See page 31 for
instructions on learning remote codes.
Resetting the Remote
To reset the remote to its factory defaults, simultaneously press and
hold the TV Source Selector and the “0” Alphanumeric Key. When the
TV Button re-lights, enter the code “333”. When the TV Button goes
out, and all of the Source Selectors flash, the remote will have been
fully reset.
Processor Reset
There may be instances when you wish to fully reset the AVR 3550HD to
its factory defaults, or the unit may behave erratically after a power surge.
To correct erratic behavior, first try turning the Master Power Switch off
and unplugging the AC power cord for at least three minutes. Plug the
cord back in and turn the receiver back on. If this doesn’t help, try a
system reset.
NOTES:
• A system reset erases all user configurations, including video
resolution, speaker and level settings, and tuner presets. After
a reset, you will need to reenter all of these settings.
• 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 the receiver 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 in the display.
Follow the directions in the note on page 34 to restore the picture
if necessary.
If the receiver still 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.
