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 SystemPower Control button
the Tone Mode button
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.
2
. Next press and hold
8
for three seconds.
NOTE: Resetting the processor will erase any
configuration settings you have made for
speakers,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 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.
