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



. Next, press and hold the Surround Mode

Button



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.
