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 AVR21EN’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
Standby/On Button [square 2]. Next, press and hold the Surround Mode Group Selector
[square 4] and the Tuner Mode Selector [square 18] buttons for three seconds.
The unit will turn on automatically and display the
RESET message in the AVR Upper Display
Line [square 34]. 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 Audioaccess service center.
