use an isolation transformer. However, the use of isolation
transformer will help protect test instrument.
(2) Adjustment must be done in the correct order.
(3) The adjustment must be performed in the circumstance of
25 °C ± 5 °C of temperature and 65 % ± 10 % of relative
humidity if there is no specific designation.
(4) The input voltage of the receiver must keep 100-220 V,
50/60Hz.
(5) The receiver must be operated for over 5 minutes prior to
the adjustment when module is in the circumstance of
above 15 °C.
In case of keeping module is in the circumstance of 0 °C, it
should be placed in the circumstance of above 15 °C for 2
hours.
In case of keeping module is in the circumstance of below
-20 °C, it should be placed in the circumstance of above 15
°C for 3 hours.
* Caution
When a still image is displayed for 20 minutes or longer
(especially where W/B scale is strong. Digital pattern 13ch
and/or Cross hatch pattern 09ch), there can some
afterimage in the black level area.

4. White Balance Adjustment
4.1. Overview
4.1.1. W/B adj. Objective & How-it-works
(1) Objective: To reduce each Panel's W/B deviation
(2) How-it-works: When R/G/B gain in the OSD is at 192, it
means the panel is at its Full Dynamic Range. In order to
prevent saturation of Full Dynamic range and data, one of
R/G/B is fixed at 192, and the other two is lowered to find
the desired value.
(3) Adj. condition: normal temperature
1) Surrounding Temperature: 25 °C ± 5 °C
2) Warm-up time: About 5 Min◦
3) Surrounding Humidity: 20% ~ 80%
4) Before White balance adjustment, Keep power on
status, don't power off
