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.
