2.
Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.
3.
Use an oscilloscope with more than 10 M
Ω impedance.
4.
Clean the object lens by an applicator with neutral detergent
when the signal level is low than specified value with the
following checks.
when the signal level is low than specified value with the
following checks.
5.
Check the focus bias check when optical block is replaced.
Focus Bias Check
Procedure :
1.
1.
Connect oscilloscope to TP (RF) and TP (VC) on the CD board.
2.
Press the
I/1
button to turn the power on, and press the
Z
(CD) button to open the CD disc tray.
3.
Put disc (YEDS-18) in and press the
u
(CD) button to play-
back.
4.
Confirm that oscilloscope waveform is as shown in the figure
below. (eye pattern)
A good eye pattern means that the diamond shape (
