When a general remote commander is not used:
1.
Solder lead wires to TP (DVDD) and TP (TOFF) on the BD
board severally.
2.
Connect the oscilloscope to TP (TE) of the BD board.
3.
Press the POWER button to turn ON the power.
4.
Open the front cover, and press the CD PLUS ONE button.
5.
Set the disc (YEDS-18) into the “PLUS ONE” slit.
6.
Close the front cover, and chuck the disc.
7.
Playback the fifth track of the disc.
8.
Short-circuit the lead wire connected at step 1. (The tracking
servo is turned OFF)
9.
Check the level B of the oscilliscope's waveform and the A
(DC voltage) of the center of the Traverse waveform.
Confirm the following :
A/B
×
100 = less than ± 10%
10. Disconnect the lead wire short-circuited at step 8. (The tracking
servo is turned ON.) Confirm the C (DC voltage) is almost equal
to the A (DC voltage) is step 8.
11. Turn OFF the power, and remove the lead wire connected at
step 1.
RF PLL Free-run Frequency Check
Procedure :
1.
Connect the frequency counter to TP (PLCK) of the BD board.
2.
Press the POWER button to turn ON the power.
3.
Open the front cover, and press the CD PLUS ONE button.
4.
Set the disc (YEDS-18) into the “PLUS ONE” slit.
5.
Close the front cover, and chuck the disc.
6.
Playback the fifth track of the disc.
7.
Confirm that reading on frequency counter is 4.3218 MHz ±
30 kHz.
