Figure 18
By pressing PLAY, the user confirms that the disc motor is
running; pressing PAUSE indicates the disc motor does
not work. Pressing NEXT proceeds to the next test, after a
reset of the disc motor (nucleus BeDiscMotorOff). If the
user presses NEXT before pressing PLAY or PAUSE, the
result of this test will be TRUE (disc motor is running).
3.5 FOCUS TEST(visual test)
The fourth Basic Engine test tests the focussing; first
focussing is turned on by calling nucleus BeFocusOn. The
display looks as follows:
Figure 19
By pressing PLAY, the user confirms that the focussing
was succesful; pressing PAUSE indicates a focussing
failure.
Pressing NEXT proceeds to the next test after a reset of
the focussing (nucleus BeFocusOff); if NEXT is pressed
before PLAY or PAUSE, the result of this test will be TRUE
(focus successful).
3.6 RADIAL TEST(visual & listening test)
The fifth Basic Engine test tests the radial functionality
(nucleus BeRadialOn); the local display looks as follows:
Figure 20
By pressing PLAY, the user confirms that the radial
function worked; pressing PAUSE indicates the function
does not work.
Pressing NEXT proceeds to the next test, after a reset of
the radial (nucleus BeRadialOff). If the user presses NEXT
before pressing PLAY or PAUSE, the result of this test will
be TRUE (radial successful).
3.7 JUMP TEST(listening test)
The sixth and last Basic Engine test tests the jumping by
c a l l i n g n u c l e i B e G r o o v e s I n , B e G r o o v e s M i d a n d
BeGroovesOut.
During this test, the local display looks as follows:
Figure 21
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-Mid-Out).
This is done in a cyclic manner; note that this test will not
contribute to the test result of the Basic Engine. Pressing
NEXT proceeds to the next test, after the disc motor has
been shut off with a call to nucleus BeDiscMotorOff.
3.8 TRAY TEST
As a last action for the Basic Engine tests, the tray test is
repeated. The local display looks as follows:
Figure 22
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 NEXT key.
