TRAY TEST

First, the tray is tested. The purpose of this test is also to give
the user the opportunity to put a disc in the tray of the DVD
player. Some tests on the Basic Engine require that a disc(e.g.
DVD MPTD test disc) is present in the player. At the end of the
Basic Engine tests this tray test will be repeated solely to
enable the user to remove the disc in the tray. The local display
will look as follows:

By pressing PLAY or PAUSE the user can toggle the position

of the Basic Engine. Pressing NEXT will proceed to the next
test, after the tray has been closed (by the software) if it was
open.
SLEDGE TEST(visual test)
The second Basic Engine test tests the sledge; the user can
move the sledge as many times as desired by using PLAY
(nucleus BeSledgeOut) and PAUSE (nucleus BeSledgeIn).
Pressing NEXT on the local keyboard proceeds to the next test.
Note that this test will not contribute to the test result of the
Basic Engine. The local display will look as follows during the
sledge test:
