6.3. Method & notice
(1) Serial number D/L is using of scan equipment.
(2) Setting of scan equipment operated by Manufacturing
Technology Group.
(3) Serial number D/L must be conformed when it is produced in
production line, because serial number D/L is mandatory by
D-book 4.0.
* Manual Download(Model Name and Serial Number)
If the TV set is downloaded by OTA or Service man, sometimes
model name or serial number is initialized.(Not always)
There is impossible to download by bar code scan, so It need
Manual download.
1) Press the "Instart" key of Adjustment remote control.
2) Go to the menu "6.Model Number D/L" like below photo.
3) Input the Factory model name or Serial number like photo.
4) Check the model name Instart menu. → Factory name displayed.
