PROGRAMMING THE REMOTE  49

As you add components to your home-theater sys-
tem, occasionally you may wish to totally repro-
gram the remote control without the confusion of
any commands, macros or ”Punch-Through“ pro-
gramming that you may have done. To do this, it is
possible to reset the remote to the original factory
defaults and command codes by following these
steps. Note, however, that once the remote is
reset, all commands or codes that you have
entered will be erased and will need to be 
re-entered:

1. Press any of the Input Selector buttons 

4

and the ”O“ button 

H at the same time until

the Program/SPL Indicator 

2 begins to flash

amber.

2. Press the ”3“ button 

H three times.

3. The red LED under the Input Selector

4 will

go out and the Program/SPL Indicator 

2 will

stop flashing and turn green.

4. The Program/SPL Indicator 

2 will remain

green until the remote is reset. Note that this may
take a while, depending on how many commands
are in the memory and need to be erased.

5. When the Program/SPL Indicator 

2 goes

out, the remote has been reset to the factory set-
tings.

52 TROUBLESHOOTING GUIDE

In the rare case where the unit’s operation or the
displays seem abnormal, the cause may involve
the erratic operation of the system’s memory or
microprocessor.

To correct this problem, first unplug the unit from
the AC wall outlet and wait at least three min-
utes. After the pause, reconnect the AC power
cord and check the unit’s operation. If the system
still malfunctions, a system reset may clear the
problem.

To clear the AVR’s entire system memory includ-
ing tuner presets, output level settings, delay
times and speaker configuration data, first put
the unit in Standby by pressing the System
Power Control button 2. Next, press the
Tone Mode 8 and the RDS ^ buttons simul-
taneously.

The unit will turn on automatically and display
the R E S E T message in the Main
Information Display ˆ. Note that once you
have cleared the memory in this manner, it is nec-
essary to re-establish all system configuration
settings and tuner presets.

NOTE: Resetting the processor will erase any
configuration settings you have made for speak-
ers, output levels, surround modes, digital input
assignments as well as the tuner presets. After a
reset the unit will be returned to the factory 
presets, and all settings for these items must be
re-entered.

If the system is still operating incorrectly, there
may have been an electronic discharge or severe
AC line interference that has corrupted the 
memory or microprocessor.

If these steps do not solve the problem, consult
an authorized Harman Kardon service depot.
