On the TV screen, a colour bar (generated by nucleus
VideoColDencOn) is visual and the internally generated
pinknoise is audible. By pressing PLAY, the user confirms
the test; pressing PAUSE will indicate the sound was
inaudible or incorrect. Pressing NEXT will proceed to the
next test; if the user presses NEXT without pressing PLAY
or PAUSE first, the result of this test will be TRUE (sound
ok). By pressing the NEXT button, there will be switched
over to the external source, this must become now visible
on the TV screen (using the SCART). The local display
indicates:

The internally generated colour bar is still available on the
CVBS and Y/C outputs. And the pinknoise-signal is still
available on the cinch audio outputs. By pressing the
PREV button, the internal generated colour bar becomes
visual again.
The test can be left by pressing the NEXT key for more
than one second.

By pressing the NEXT key, the Basic Engine tests are
started.
3.2 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 looks as follows:

By pressing PLAY or PAUSE, 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 NEXT will
proceed to the next test, after the tray has been closed (by
the software) if it was open.
3.3 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
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 looks as follows during the
sledge test:
