3. Notes

When unable to adjust using AC adaptor, use voltage regulator and supply power to be VCC-1-1
(CP149) = 5.0 ± 0.05 V.

3-5. BL drive voltage adjustment

1. Preparation

• AC adaptor or voltage regulator

• Multimeter

2. Adjustment procedure

Make sure that CP910 (BL-VCC) is within 5.4 ± 0.2V.

3. Notes

When unable to adjust using AC adaptor, use voltage regulator and supply power to be VCC-1-1
(CP149) = 5.0 ± 0.05 V.

3-6. VCOM AC adjustment and VCOM DC coarse adjustment

1. Preparation

• AC adaptor or voltage regulator

• Digital oscilloscope

2. Adjustment procedure

(1) Make sure amplitude of VCOM output (CP176) is 6.6 ± 0.3 V.
(2) Adjust VR320 so that maximum VCOM output (CP716) will be 4.8 ± 0.2 V.

3. Notes

When unable to adjust using AC adaptor, use voltage regulator and supply power to be VCC-1-1
(CP149) = 5.0 ± 0.05 V.

1. Preparation

• AC adaptor or voltage regulator

• Digital oscilloscope

2. Adjustment procedure

(1) Start up Test mode Menu1.
(2) Select GRAY SCALE (10 step).
(3) Trigger VB waveform (CP335) by FRP (CP346) signal to adjust as noted below.
(4) Adjust RGB-AMP VR (VR340) so that pedestal-pedestal voltage of VB(CP335) signal is 3.5 ±

0.05 V.
(5) Adjust contrast VR (VR344) so that contrast terminal voltage (CP305) is 3.0 ± 0.05 V temporary.
(6) Adjust Bright VR (VR381) so that potential between VB (CP335) signal’s pedestal and 3 step is

2.20 ± 0.05 V.
(7) Adjust contrast VR (VR344) so that potential between VB (CP335) signal’ s pedestal and 10 step

is 2.85 ± 0.05 V.
✻ Make sure that waveforms are not distorted.

3. Notes

When unable to adjust using AC adaptor, use voltage regulator and supply power to be VCC-1-1

TROUBLESHOOTING

Trouble1 : Power turns off while in operation.

cause1

To prevent CF data error, the unit will automatically turn off when CF cover opens.
For product serial number 1022100 (program version 98082901) a shock to the camera (i.e. key
operation, lens rotation, etc.) may produce chattering to CF switch which may erroneously detect
that CF cover is open. To prevent this change the software.

Program to use (CF card × 1)
KX-778PROGRAM Ver. 100102

Action1 (Procedure to change software)

Note1: Use AC adaptor when changing program.
Note2: While TEST MODE is displayed, always follow the operations shown.
Others: For regular operations such as inserting or ejecting CF card, refer to owner’s manual.

(1) Error check

Insert the CF card that comes with the unit.
Turn power on, then tap the right side of the unit with finger. Make sure power turns off detecting
a shock. (Even if it dose not turn off, proceed to the next step.)

(2) Check program Ver.

Turn power on pressing DISP button and MENU key at the same time.
(TEST MODE appears on the screen.)
Only proceed when program Ver. 98082901 is displayed.
