9. Data clear
Prior to the data registration shown in 8 above, pressing the
ESC switch clears the changed data and returns to the previous
data that is not changed.
(2) File data registration or change
Nine types of preset data (HUE, CHROMA, BRIGHTNESS,
CONTRAST, G/B.GAIN, R/G/B.BACKGROUND) can be
registered in files. There are four types of files, REF, FILE1,
FILE2 and FILE3. The color temperature below is factory-set
in each file.

4.4 Adjustment procedures
(Introduction)
• The following adjustments can be made with higher accuracy
in the darkest possible use environments for the monitor.
• Read "Registering/changing PRESET data" in 4.3 before
proceeding to the adjustments below.
(1) Brightness adjustment
a. Brightness
The BRIGHTNESS is a control for setting a proper black level.
The black level must always be adjusted according to the
brightness in the monitor use environments so as to avoid too
high or too low a black level.
An optional ASP-80 for automatic adjustments is available.
b. Adjustment steps
1. Input signal
Input a gray scale signal with pluge portion.
A-portion
-2%
Fig. 4-4-1 pluge portion
2. BRIGHTNESS adjustment
While looking at the pluge portion (figure above) in the center
of the signal, decrease the BRIGHTNESS until just before
the brightness of the A-portion (-2%) and that of the B-portion
(0%) in the figure are visually indistinguishable from each
other.
Make sure here that slight brightness of the C-portion (+2%)
is recognizable. If it is unrecognizable, increase the
BRIGHTNESS until the C-portion brightens slightly, since
the black level is too low.
(2) Contrast adjustment
a. Contrast
The CONTRAST is factory-set in such a way that video images
are monitored optimally.
An optional ASP-80 for automatic adjustments is available.
b. Caution
If the CRT is left excessively brilliant for a long time, the lifetime
of it will be shortened. The PRESET value must be therefore
adjusted to the value shown below where possible.
