Note: If the SUB BRT value exceeds 32, make sure that there is no noisy
black of 0IRE.
Though the SUB CON value is generally lowered only, if it is to be
raised, take care not to cause the white blurring.
3. If the SUB CON value was changed, check the white balance
and repeat adjustment to attain best sub brightness, sub con-
trast, and white balance.
4. After the adjustment finished, write the data by pressing the
[MUTE] + [ENTER] buttons on the remote commander.
3-5. SCREEN CENTER ADJUSTMENT
1. Enter the RF monoscope signal.
2. Adjust so that the picture is displayed in the center of the
