When tightening a screw, have both sides of the lens block assembly
so as not for the load to depend.

The DSC-P10/P12 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 mechanism
end when the power is turned off.
Though the position data is calibrated at the “Flange Back
Adjustment”, 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

perform the “Flange Back Adjustment”.
Thus, new position data will be written.
