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 includ- ing tuner presets, output level settings, delay times and speaker configuration data, first put the unit in Standby by pressing the System Power Control button 2. Next press and hold the Tone Mode button 8 for three 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 configura- tion settings and tuner presets.

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 Harman Kardon service depot.
