Adjustment method:
1. Adjust with VR511 to 200
±
1 kHz.
7. 3.4 V (D) C Voltage Adjustment 1
Adjustment method:
1.Adjust with VR512 to 3.40
±
0.03 V
8. 3.4 V (D) C Voltage Adjustment 2
Note:
1. Item 8 adjustment should be carried out after item 7.
Adjustment method:
1. Shorten CL579 and CL589 with lead wire.
2. Adjust with VR515 to 3.70
±
0.03 V.
3. Remove the lead wire between CL579 and CL589, and con-
firm the voltage is 3.4 V.
9. 12.4 V (L) Voltage Adjustment 1
Adjustment method:
1. Set the main switch to the play mode.
2. Adjust with VR514 to 12.40
±
0.05 V.
10. 12.4 V (L) Voltage Adjustment 2
Adjustment method:
1. Set the main switch to the camera mode, and turn on the
LCD.
2. Adjust with VR513 to 12.40
±
0.05 V.
11. CCD VSUB Adjustment
Note:
1. When installing a new CCD, read the abbreviation described
on the rear side of CCD, and write it to the board.
2. If the CCD, each board and parts replaces, it is necessary
to adjust again.
Adjustment method:
1. Disconnect CN303 on the SY1 board. Turn on the power,
and set so that the through screen from the CCD can be
seen on the LCD.
2. Read the abbreviation display on the rear side of CCD (side
A of CA-1 board). Convert these to voltages using the table
below. For example, “h”
→
VSUB = 11.7 V
3. Adjust with VR921 so that the voltage of TP921 at VSUB
becomes the displayed voltage value
±
0.1 V.
12. AWB Adjustment
Preparation:
POWER switch: ON
Adjusting method:
1. When setting the camera in place, set it to an angle so that
nothing appears in any part of the color viewer except the
white section. (Do not enter any light.)
2. Double-click on the DscCalDi128c.
3. Click the AWB, and click the Yes.
