Processor Reset
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 minutes. 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 including
tuner presets, output level settings, delay times
and speaker configuration data, first put the unit in
Standby by pressing the System Power Control
button
1
. Next, press and hold the Surround Mode
Button
6
for 5 seconds.
The unit will turn on automatically. Note that once
you have cleared the memory in this manner, it is
necessary to re- establish all system configuration
settings and tuner presets.
NOTE: Resetting the processor will erase any
configuration settings you have made for speakers,
output levels, surround modes and 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 reentered.
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.
