Dark Siemens star chart.

Check that the data of page: 6, address: 02 is “00”.
If not, turn the power of unit OFF/ON.

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-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.

When Replacing the Video Lens
1) With current video lens assembled, turn the power on, and set

the bit value of Bit0 on Page:9, Address:17 to “0” using the
adjusting remote commander, 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.

3) After the “Flange Back Adjustment”, return the bit value of

Bit0 on Page:9, Address:17 to “1” using the adjusting remote
commander.

When Replacing the SY-77 Board
1) Replace the SY-77 board with a new one, set the mode dial to

“PLAY”, turn the power on, and set the bit value of Bit0 on
Page:9, Address:17 to “0” using the adjusting remote com-
mander, 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.

3) After the “Flange Back Adjustment”, return the bit value of

Bit0 on Page:9, Address:17 to “1” using the adjusting remote
commander.
