During the test, the following display
is shown: the counter counts down
from the number of nuclei to be run
before the test finishes. Example:
SET O.K.?
YES
NO
To exit DEALER SCRIPT, unplug the power cord
Due to the complexity of the DVD recorder, the time to find
a defect in the recorder can become long. To reduce this
time, the recorder has been equipped with Diagnostic and
Service software (DS). The DS offers functionality to
diagnose the DVDR hardware and tests the following:
• Interconnections between components
• Accessibility of components
• Functionality of the audio and video paths
This functionality can be accessed via several interfaces:
1. End user/Dealer script interface
2. Player script interface
1. End User/Dealer Script Interface
1.1 Description
The End user/Dealer script interface gives a diagnosis on
a stand alone DVD recorder; no other equipment is
needed. During this mode, a number of hardware tests
(nuclei) are automatically executed to check if the recorder
is faulty. The diagnosis is simply a "fail" or "pass"
message. If the message "FAIL" appears on the display,
there is apparently a failure in the recorder. If the message
"PASS" appears, the nuclei in this mode have been
executed successfully. There can be still a failure in the
recorder because the nuclei in this mode don't cover the
complete functionality of the recorder.

The End use/Dealer script executes all diagnostic nuclei
that do not need any user interaction and are meaningful
on a standalone DVD recorder.
