Processor Reset

In the rare case where the unit’

s operation or the dis

plays seem abnormal, the cause may involve the erratic

operation of the system’s memory or microprocessor.

o 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 430’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

Standby/On Switch 1.

Next,

press

and hold the

Surround Mode Group Selector 2

and the Tuning Mode Selector 8 buttons for three

seconds.

The unit will turn on automatically and display the

RESET message in the Upper Display Line #.

NOTE: Resetting the processor will erase any configu-

ration settings you have made for speakers, output

levels

surround modes

, digital input assignments as

well as the tuner presets. 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 Har

man Kardon ser

vice center
