Processor Reset

In the rare case in which the unit’s operation or 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 sys- tem “reset” may clear the problem.

To clear the AVR 225’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 6 for three seconds.

The unit will turn on automatically and display the RESET message in the Main Information Display S. Note that once you have cleared the memory in this manner, it is necessary to reestablish all system configuration settings and tuner presets.

The reset will not affect settings that were pro- grammed into the remote control. To reset the remote control and restore it to its factory default settings, please follow the instructions on page 34.

If these steps do not solve the problem, consult an authorized Harman Kardon service center. You can locate the service center nearest to you by visiting our Web site at www.harmankardon.com.

Memory Backup

This product is equipped with a memory backup system that preserves the system configuration infor- mation and tuner presets if the unit is accidentally unplugged or subjected to a power outage. This mem- ory will last for approximately one week, after which time all information must be reentered.
