2-1-2. Notes on Adjustment

Because DSR-250/250P can select the aspect ratio 16:9 or
4:3, some adjustment items need changing the setting of
the aspect ratio. (Refer to Section 2-2-6, Picture Frame
Adjustment.) Changing of the aspect ratio is done in the
16:9 WIDE setting of the CAMERA SET menu.
When the aspect ratio is not specified, perform adjustment
in the 4:3 mode (16:9 WIDE → OFF).
