Troubleshooting
Processor Reset
In the rare case in which 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 3 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 1
. Next, press and hold the Surround Mode Group
Selector 3
and the Tuner Mode Selector Buttons H for
3 seconds.
The unit will turn on automatically and display the
RESET
message in the AVR Upper Display Line . 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
Audioaccess service center.
