3-1-3. Notes on Adjustment
1. This “ALIGNMENT” is used for the adjustment of
DXF-701/701CE and DXF-701WS/701WSCE.
Therefore, when adjusting DXF-701/701CE, use the
video camera DXC-D30/D30P.
Also, in case of DXF-701WS/701WSCE, use the video
camera DXC-D30WS/D30WSP.
2. When adjusting DXF-701WS/701WSCE, set the DXC-
D30WS/D30WSP to “4:3” position. But, when
performing procedure 7 of “3-2-6. Picture Frame
Adjustment”, set the DXC-D30WS/D30WSP to “16:9”
position.
Therefore, regarding the setting manner of “16:9” or
“4:3”, refer to item of “Menu screen” of “2-7.
SERVICE MODE OPERATION” in the service
manual DXC-D30WS/D30WSP Vol.1, select the
ADVANCE menu “PAGE 9”, and set “16:9” or “4:3”.
