Memory Backup

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

System 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 system’s memory, press and hold the MEMO òand CLEAR ó

buttons at the same time for a few seconds. After clearing the memory it will be necessary to re-establish all system configuration information and tuner presets.

If the system is still operating incorrectly, there may have been an electrostatic discharge or severe AC line interference that has corrupted the memory or microprocessor.

If a reset does not solve the problem, consult an authorized Harman Kardon service depot.
