DEALER SCRIPT

7.1.1

Purpose of Dealer Script

The dealer script can give a diagnosis on a standalone DVD
player; no other equipment is needed to perform a number of
hardware tests to check if the DVD player is faulty. The
diagnosis is simply a "error" or "pass" message; no indication
is given of faulty hardware modules. Only tests within the scope
of the diagnostic software will be executed hence only faults
within this scope can be detected.
