SAFETY PRECAUTIONS
IMPORTANT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics. These parts are identified by in
the Exploded View.
It is essential that these special safety parts should be replaced with the same components as recommended in this manual to prevent
Shock, Fire, or other Hazards.
Do not modify the original design without permission of manufacturer.

over 1 W), keep the resistor 10 mm away from PCB.
Leakage Current Hot Check circuit
Keep wires away from high voltage or high temperature parts.
Before returning the receiver to the customer,
always perform an AC leakage current check on the exposed
metallic parts of the cabinet, such as antennas, terminals, etc., to
be sure the set is safe to operate without damage of electrical
shock.
Leakage Current Cold Check(Antenna Cold Check)
With the instrument AC plug removed from AC source, connect an
electrical jumper across the two AC plug prongs. Place the AC
switch in the on position, connect one lead of ohm-meter to the AC
plug prongs tied together and touch other ohm-meter lead in turn to
each exposed metallic parts such as antenna terminals, phone
jacks, etc.
If the exposed metallic part has a return path to the chassis, the
measured resistance should be between 1 MΩ and 5.2 MΩ.
When the exposed metal has no return path to the chassis the
reading must be infinite.
An other abnormality exists that must be corrected before the
receiver is returned to the customer.

(1) Because this is not a hot chassis, it is not necessary to
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.
3.3.2. LAN inspection solution
- LAN Port connection with PCB
(4) The input voltage of the receiver must keep AC 100-240
- setting automatic IP

(5) The receiver must be operated for about 5 minutes prior to
the adjustment when module is in the circumstance of over
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.
- If you want manual connection, enter Network connection at

5. White Balance Adjustment
5.1. White Balance Adjustment
5.1.1. Overview
(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) Adjustment condition : normal temperature
① Surrounding Temperature : 25 ± 5 °C
② Warm-up time: About 5 Min
③ Surrounding Humidity : 20 % ~ 80 %
5.1.2. Equipment
