Procedure :
1.
1.
Connect oscilloscpe to test point TP (TE) on BD board.
2.
Turn Power switch on.
3.
Put disc (YEDS-18) in to play the number five track.
4.
Press the
P (Pause) button. (Becomes the 1 track jump mode)
5.
Check the level B of the oscilliscope's waveform and the A

ELECTRICAL BLOCK CHECKING
Note:
1.
CD Block is basically designed to operate without adjustment.
Therefore, check each item in order given.
