4. PCB assembly adjustment method
4.1 Input Tool-Option, Area Option
Option adjustment following BOM (Tool Option 1, Area Option)
* Required Equipments
- Remote controller for adjustment
* Profile : Must be changed the option value because being
different with some setting value depend on module
maker, inch and market.
Adjustment method
The input methods are same as other chassis.(Use IN-START
Key on the Adjust Remocon.)

/
D
(CH+/-) key
, and press the number key(0~9) consecutively

number key “7”
(If not changed the option, the input menu can differ from the
model spec.)
* Refer to Job Expression of each main chassis ass’y
(EBTxxxxxxxx) for Option value
* Before PCB check, you have to change the Tool option,
Areaoption and have to AC off/on (Plug out and in)
(If missing this process, set can operate abnormally)
* Never push the IN-STOP KEY after completing the function
inspection.
