Pressing STOP indicates the disc motor does not work. Pressing PLAY proceeds to the next test, after a reset of the disc motor (nucleus BeDiscMotorOff). If the user presses PLAY before pressing OPEN/CLOSE or STOP, the result of this test will be TRUE (disc motor is running). 5.5.5 Focus Test (Visual Test) The fourth Basic Engine test tests the focussing. First focussing is turned on by calling nucleus BeFocusOn. The display will look as follows:

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:

Figure 5-26 By pressing OPEN/CLOSE the user confirms that the focussing was succesful. Pressing STOP indicates a focussing failure. Pressing PLAY proceeds to the next test after a reset of the focussing (nucleus BeFocusOff). If PLAY is pressed before OPEN/CLOSE or STOP, the result of this test will be TRUE (focus successful). 5.5.6 Radial Test (Visual & Listening Test) The fifth Basic Engine test tests the radial functionality (nucleus BeRadialOn). The local display looks as follows:

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.
