ADJUSTMENT
1-1. Loading color parameter
Execute when replacing camera unit
Load parameter in memory of camera unit. (Light box not needed.)
(1) Set QV-770 to “PLAY” mode. (Computer communication does not work in “REC” mode.)
(2) Connect QV-770 and PC with link cable RS-232.
(3) Operate adjustment software on MS-DOS.

1-2. Defect correct
When there is a blurred black dot in a white display it is called a defect.
To correct this use the data next to this.
• Perform this adjustment after loading color parameters.

Set QV-770 to “REC” mode.
Start test program. (Refer to “1-8. Test program”.)
Choose “DEFECT CORRECT” from test program and execute.
Make sure “ ” mark on LCD turns from red to blue.
Turn power off.
Notes: • Make sure no light goes through CCD.
• As the adjustment data is written in the EEPROM by the POWER switch operation, do not forget
to turn it off using the switch.
• Pixel compensations are performed up to two pixel defects.
• The compensation data is deleted once you exit the mode.
AD-C620
QV-770
Block CCD completely from light.
1-3. Strobe adjust
Execute after replacing strobe and loading color parameter, because strobe adjustment informations are
deleted.
• Loading color parameter and Defect correct should be done before.
• Distance between strobe lens and gray paper should be one meter.
• The adjustment must be done in a dark room.
• For gray paper use Superior Oxford Gray No.22. (Note: Use lighter color surface of the paper.)
• The two sizes listed below are available as spare parts. (Can also found in camera store.)

Shoot a picture of a specified gray paper. Flash icon should be red before shooting.
Make sure that the flash icon on LCD turns from red to blue.
Turn power off.
Note: As the adjustment data is written in the “EEPROM” by the “POWER” switch operation, do not forget
to turn it off using the switch.

Checking if there is a false operation triggered by a distorted waveform when using strobe.
• Set strobe adjustment.
• Input DC in 6.0 ± 0.1 V.
(1) Set QV-770 to “REC” mode.
(2) Monitor the trigger waveform on digital oscilloscope and check the display.
(3) Automatically recharged after shooting picture.
Make sure that the DC in 6.0 V current does not exceed 1.2 A.
(4) Set QV-770 to “PLAY” mode and check the display.

BL drive voltage adjustment
• Voltage supply
VCL0 (CP101)=5.0±0.05[V]
Apply 3.3 V ± 5% to PW.
(You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.)
(1) Apply 5.0 ± 0.05 V to VCL0 and adjust VR900 so that CP901(VBL) will be 6.1 ± 0.1 V.
Notes: • Make sure that the current consumption is not abnormally large.
• CN920 is open.

VEE2 = –15.0 ± 0.05 (V) (CP182).
(You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.)
(1) Make sure that the amplitude of VCOM output (CP771) is 6.6 ± 0.3 V.
(2) Adjust VR770 so that the potential of VCOM output (CP711) will be 4.8 ± 0.2 V.

VCL0 (CP101)=5 V ± 0.05 (V).
Apply 3.3 V± 5% to PW.
Connect PCB-LB and input.
(You can use an AC adaptor however, for the checking after repairs, apply above mentioned voltages.)
(1) Adjust VB waveform (CP324) as shown below by triggering FRP (CP305) signal.
(2) Adjust waveform A at 3.5 ± 0.05 V by adjusting RGB, AMP VR(VR302).
(3) Adjust contranst terminal voltage (CP306) at 1.5V ± 0.05V by adjusting contrast VR (VR303).
(4) Keep waveform B at 2.1 ± 0.05V by adjusting Bright VR (VR304).
(5) Keep waveform C at 2.9 ± 0.05V by adjusting contrast VR (VR303).
Note: • Make sure that waveforms are not distorted.
