3) COMPONENT (480i)
4) RGB(PC : 1920 x 1080 @ 60Hz)
5) HDMI1/2
6) PC Audio In
* Display and Sound check is executed by Remote controller
* Caution : Not to push the INSTOP KEY after completion if the
function inspection.

* Caution: Set up "RF mode" before launching products.
4.3.3. 3D function Check(Model name: DM~)
■ Test equipment
1) Pattern Generator MSHG-600 or MSPG-6100 (HDMI 1.4
support)
2) Pattern: HDMI mode (Model No. 872, Pattern No. 83)
■ Test method
1) Input 3D test signal as Fig.1.
2) Press ‘OK" key as a 3D input OSD is shown.
3) Check pattern as Fig2 without 3D glasses. (3D mode
without 3D glasses)
4.4. White balance adjustment
RGB_Gains are fixed data for each model.
Insert RS-232C Jack which is connected with PC for White
Balance or equivalent device.
* Total Assembly line should be check whether the color
coordinate(x,y) data refer to below table were meet or not.
*Note : x,y coordinates are drifted about 0.007 after 30 mins
heat-run. So checking color coordinate within 5-min at
total assembly line, consider x,y coordinates might be
up to 0.007 than x,y target of each color temperature.
*Note : Manual W/B process using adjusts Remote control.
1) After enter Service Mode by pushing "ADJ" key,
2) Enter "White Balance" by pushing "►" key at "White
Balance".
* When doing Adjustment, Please make circumstance as
