Note 3:
The attachment lenses are not used.
Note 4:
Take care not to hit the mini-pattern box when ex-
tending the lens.
2) Install the minipattern box so that the distance between it and
the front of lens of camera is less than 3 cm.
3) Make the height of minipattern box and the camera equal.
4) Check the output voltage of the regulated power supply is the
specified voltage 
± 0.01 Vdc.
5) Check that the center of Siemens star chart meets the center of
shot image screen with the zoom lens at TELE end and WIDE
end respectively.
Specified voltage: The specified voltage varies according to the
minipattern box, so adjustment the power sup-
ply output voltage to the specified voltage writ-
ten on the sheet which is supplied with the mini-
pattern box.

Perform “Flange Back
Check “.
[Precaution on Replacing the Video Lens or the SY-83
Board]
The DSC-P8 uses the position sensor to detect the zoom position.
Accordingly, the zoom position will vary if the position data
changes due to the replacement of the video lens or the SY-83
board, thus causing the video lens to collide against the mecha-
nism end when the power is turned off.
Though the position data is calibrated at the “Flange Back Adjust-
ment”, add the following work when making an adjustment at the
replacement of video lens to prevent a collision of video lens.
When Replacing the Video Lens
1) With current video lens assembled, turn the power on, and set
the data of page: 6F, address: 3E to “FF”, then turn the power
off.
2) Replace the video lens with a new one, turn the power on, and
perform the “Flange Back Adjustment”.
Thus, new position data will be written.
When Replacing the SY-83 Board
1) Replace the SY-83 board with a new one, set the mode dial to
“PLAY”, turn the power on, and set the data of page: 6F,
address:3E to “FF”, then turn the power off.
2) Set the mode dial to “CAMERA”, turn the power on, and per-
form the “Flange Back Adjustment”.
Thus, new position data will be written.
