ADJUSTMENT
1. Face the picture tube in an east-west direction. (For best condition.)
2. Complete V-PIN and V-CEN adjustments fi rst (A2170-D1 06 V-PIN,
A2170-D1 05 V-CEN).
3. Input a monoscope and crosshatch signal. Adjust the picture
distortion with the following service parameters to balance the best
condition for these two signals.
NOTE:
Make sure that the picture size is within specs. Vertical size is
11.8 ± 0.1 sq. and horizontal size is 15.8 ± 0.1 sq.
4. Write data into memory before changing modes.

not performed for full mode.
3. Adjust the geometry similar to Full DRC mode. Vertical size is 11.7
± 0.1 sq. and horizontal size is 15.6 ± 0.1 sq., if monoscope signal is
available. Otherwise, set the Vertical size to 91.0 ± 0.6% scan and
Horizontal size as 91.0 ± 0.6% scan.
4. Use the following register to adjust the horizontal parameter:
A2150-D2
