[Precaution on Replacing the Video Lens or the SY-77
Board]
Board]
The DSC-P7 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-77
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.
