3-4. Setup
1. System requirements
Windows 98 or Me or 2000 or XP
IBM R -compatible PC with pentium processor
CD-ROM drive
3.5-inch high-density diskette drive
USB port
40 MB RAM
Hard disk drive with at least 15 MB available
VGA or SVGA monitor with at least 256-color display
2. Installing calibration software
1. Insert the calibration software installation diskette into your
diskette drive.
2. Open the explorer.
3. Copy the DscCalDI_140 folder on the floppy disk in the FD
drive to a folder on the hard disk.
3. Installing USB driver
Install the USB driver with camera or connection kit for PC.
4. Pattern box (color viewer)
Turn on the switch and wait for 30 minutes for aging to take
place before using Color Pure. It is used after adjusting the
chroma meter (VJ8-0192) adjust color temperature to 3100 ±
20 K and luminosity to 900 ± 20 cd/m
the lump and its circumference are high temperature during
use and after power off for a while.

Note:
1. Frequency adjustment is necessary to repair in the CP1
board and replace the parts.
2. Carry out the oscillation frequency adjustment in the CP1
board.
3. Power voltage sets +4.0 V.
Preparation:
1. Connect CL501 and CL531 with lead wire on the CP1 board
(side A).
2. Input +4.0 V by using cable adaptor from CN105.

Adjustment method:
1. Adjust with VR501 to 496.5 ± 1 kHz.

496.5 ± 1 kHz
1. Double-click on the DscCalDi.exe. (When setting Monitor in
the LCD ”Test”, LCD monitor can be seen.)
Measuring point is TP971.
2. Click the Hall Cal.
3. Repeat the third time “Open” and “Close” in the APERTURE.
4. Select “Open” in the APERTURE.
5. Adjust with GAIN to 3.00 V ± 0.01 V.
GAIN (ROUGH): “+1” → +100 mV, “–1” → –100 mV
GAIN (FINE): “+1” → +10 mV, “–1” → –10 mV
6. Select “Close” in the APERTURE.
7. Approximately half of the offset from 1 V is adjusted using
GAIN. For example for 1.2 V, GAIN can be used to adjust so
that (1.2-1.0) / 2 + 1.0 = 1.1 V.
GAIN (ROUGH): “+1” → –100 mV, “–1” → +100 mV
GAIN (FINE): “+1” → –10 mV, “–1” → +10 mV
8. Adjust with OFFSET to 1.00 V ± 0.01 V.
OFFSET (ROUGH): “+1” → +100 mV, “–1” → –100 mV
OFFSET (FINE): “+1” → +10 mV, “–1” → –10 mV
9. Select “Open” in the APERTURE. Check that the voltage is
3.00 V ± 0.03 V.
If the values are different, readjust from step 5.
10. Select “Close” in the APERTURE. Check that the voltage
is 1.00 V ± 0.03 V.
11. Click the OK.
Note:
If the GAIN and OFFSET values are changed, the voltage val-
ues at OPEN and CLOSE will change, so be sure to check that
the OPEN and CLOSE values are within the standard range.
