Dark Siemens star chart.

Check that the data of page: 60, address: 02 is “00”. If
not, press the RESET switch using a thin and long pin.

If the video lens or SY-83 board was replaced, make a setting
by referring to “Precaution on Replacing the Video Lens or the
SY-83 Board” and then perform the adjustment.

Preparations before adjustments:
1) The minipattern box is installed as shown in the following fig-

ure.

The attachment lenses are not used.

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 “.

The DSC-P10/P12 uses the position sensor to detect the zoom po-
sition.
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.
