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.

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 sys- tem reset may clear the problem.

To clear the AVR 230’s entire system memory includ- ing tuner presets, output level settings, delay times and speaker configuration data, press and hold the Tone Mode Button 5 button for three seconds. The unit will turn on automatically.

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. 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 center.
