RADIAL TEST(visual & listening test) The fifth Basic Engine test tests the radial functionality (nucleus BeRadialOn); the local display looks as follows:

Figure 5-24 By pressing PLAY or PAUSE the user can move forward or backward (respectively) through the logged error codes. If "0000" is displayed at all positions, the error log is empty. Display of the logged errors is done in a cyclic manner. By pressing DNM on the local keyboard, the user can proceed to the next test.

Figure 5-21 By pressing PLAY the user confirms that the radial function worked; pressing PAUSE indicates the function does not work. Pressing DNM proceeds to the next test, after a reset of the radial (nucleus BeRadialOff). If the user presses DNM before pressing PLAY or PAUSE, the result of this test will be TRUE (radial successful).

JUMP TEST(listening test) The sixth and last Basic Engine test tests the jumping by calling nuclei BeGroovesIn, BeGroovesMid and BeGroovesOut. During this test, the local display looks as follows:

ERROR BITS Reading the error bits is done by nucleus LogReadBits. The display during the errorbits readout looks as follows:

Figure 5-22 The user can switch between the three different types of groove settings by pressing PLAY (forward to next nucleus in the list In-Mid-Out) or PAUSE (backward in the list In-MidOut). This is done in a cyclic manner; note that this test will not contribute to the test result of the Basic Engine. Pressing DNM proceeds to the next test, after the disc motor has been shut off with a call to nucleus BeDiscMotorOff.

TRAY TEST As a last action for the Basic Engine tests, the tray test is repeated. The local display will look as follows:

The error bits are used to indicate that an eror occurred once or more times; if that is the case the bit representing the error is set. To read out this field of error bits, the local display is used . Only the number of the errors where the bit is set will be displayed on the local display. The number of the set bits is displayed in a cyclic manner. Scrolling through the set error bits can be done with the PLAY key for �next� and PAUSE key for �previous�. Pressing the PLAY key at the last bit number will display the first bit number again, pressing the PAUSE button at the first bit number will display the last bit number in the list. The representation of bit numbers is decimal. If no error bits are set, the number on the right side of the display wil be �00�. See table below:

Figure 5-23 This test is meant to give the user the opportunity to remove the disc in the tray. The tray position can be toggled using the PLAY and PAUSE key. The tray will be closed (by the software, if it is open) before proceeding to the next test when the user presses the DNM key.

ERROR LOG Reading the error log and error bits information can be useful to determine any errors that occurred recently during normal operation of the DVD player. Reading the error log is done by nucleus LogReadErr. The display during the errorlog readout looks as follows :
