Note : Connect a probe (10:1) of the osilloscope or the

frequency counter to a test point.

During adjustment, connect () pin of an
oscilloscope to TP2 (VC).

1. Focus Bias Adjustment

Make the focus bias adjustment when replacing and

repairing the optical block.

1) Connect an oscilloscope to the test points TP1 (RF)

and TP2 (VC).

2) Turn on the power switch.

3) Insert test disc TCD782 and play back the second

composition.

4) Adjust SFR701 so that the RF signal of the test point

TP1 (RF) is MAX and CLEARREST.
