ADJUSTMENT INSTRUCTION
1. Application Range
This spec sheet is applied to all of the PD12A chassis. 
2. Specification
(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.
(4) The  input  voltage  of  the  receiver  must  keep  100  V  ~  240
V, 50 / 60 Hz.
(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
- 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,.
O
After  RGB  Full  White  in  HEAT-RUN  Mode,  the  receiver
must be operated prior to the adjustment.
O
Enter into HEAT-RUN MODE 
1) Press the POWER ON KEY on R/C for adjustment.
2) OSD display and screen display PATTERN MODE.
- Set is activated HEAT run without signal generator in this
mode. 
- Single color pattern ( WHITE ) of HEAT RUN MODE uses
to check panel. 
- Caution : If  you  turn  on  a  still  screen  more  than  20
minutes  (Especially  digital  pattern,  cross  hatch
pattern),  an  after  image  may  be  occur  in  the
black level part of the screen.
3. PCB assembly adjustment
