5.5.2 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 OPEN/CLOSE the user can toggle the position of
the tray. Note that this test will not contribute to the test result
of the Basic Engine. Pressing PLAY will proceed to the next
test. At this point, the tray will be closed automatically by the
software if it was open.
5.5.3 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 OPEN/
CLOSE (nucleus BeSledgeOut) and STOP (nucleus
BeSledgeIn). Pressing PLAY on the local keyboard proceeds
to the next test. Note that this test will not contribute to the test
result of the Basic Engine.

OPEN/CLOSE or STOP, the result of this test will be TRUE
(focus successful).

The fifth Basic Engine test tests the radial functionality (nucleus
BeRadialOn).
