Chassis.

(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±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  100-240V~,

50/60Hz.

(5) The receiver must be operated for about 5 minutes prior to

the adjustment.

O

After  RGB  Full  white  HEAT-RUN  Mode,  the  receiver  must

be operated prior to adjustment.

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(RED/BLUE/GREEN) of HEAT-RUN 

mode uses to check PANEL.
