Troubleshooting
Processor Reset
In the rare case where the receiver’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 receiver’s entire system memory
including 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
6
and the FM Mode
Selector
@
buttons for three seconds.
The unit will turn on automatically and display
the
RESET
message in the Main
Information Display
U
.
NOTE: Resetting the processor will erase any
configuration settings you have made for speak-
ers, 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 JBL service center.
In the event that you forget the password for
the DVD600
II
, you may reset it to the factory
default by following this procedure: In Standby
mode, press the
Search Reverse and
Skip Forward buttons on the front panel
simultaneously for more than 3 seconds. The
Information Display will light, and a
test pattern will appear on your TV. Press the
