The Selector, Command Handler and Menu Handler are the heart of the Diagnostic Software and will be referenced
as the Diagnostic Engine in the context of this document. They form a framework in which Diagnostic Nuclei and
standard Scripts can be added via a well-defined software interface. The actual contents of the Menu Handler are part
of the FDS.

Dealer diagnostics (For I2C Master Modules only)
The dealer diagnostic mode can be activated by pushing the script activation keys during power-on. The script
activation keys vary depending on the model used.
This test consists of running a predefined script (Dealer Test Script). The script controls the execution of a number
of diagnostic tests. No external input is required during the execution of the script. During the execution a
progress indicator will be displayed on the local display. At the end of the script one message is returned indicat-
ing if a failure in the DVD player is detected or not. The message will be displayed on the local display. No exter-
nal test equipment is required.

First Line & Level 3 diagnostics (For I2C Master Modules only)
The First Line & Level 3 diagnostic mode can be activated by pushing the script activation keys during power-on.
The script activation keys vary depending on the model used.
This test consists of running a predefined script (Player Test Script). The script controls the execution of a number
of diagnostic nuclei. The first group of Diagnostic Nuclei in this script will check the local display and the local
keyboard and will output the result on the local display before it continues with the remaining Diagnostic Nuclei of
the script. The Diagnostic Nuclei for the readout of the error log and the Basic Engine will also be part of the
predefined script. During execution of the script input from the local keyboard is required for confirmation of
