Processor Reset
In the rare case in which 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 totally reset the DPR 1001’s processor and clear all setting and configuration data, including all tuner presets, output level settings, delay times, surround mode choices, speaker configuration and crossover data, follow these steps:
1.Turn the unit completely off by pressing the Main Power Switch ( so that it is in the OFF position.
2.Press and hold the Tuning Mode Selector 7 and the Tuning ¤ Button 8, and at the same time press the Main Power Switch ( in so that it is in the ON position.
3.When the Upper Display Line F reads RESET, release the Tuning Mode Selector 7 and Tuning ¤ Button 8.
4.After a few seconds the unit will go into a display test mode that will illuminate all segments of the Main Information Display ^.
5.Press the Standby/On Button 2 to return the DPR to normal operation.
When the reset is complete you may return to normal operation, but remember that all system configuration settings and tuner presets will have to be reentered.
NOTE: Resetting the processor will erase any configu- ration 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 Harman Kardon service center.
