When the power plug is connected to the power line
(Standby status), all data inside the internal ROM are
written into the NVM (Nonvolatile Memory). When the
power is turned to on, required data for the current picture,
such as status memory data, etc., are selected, and they are
written into the internal RAM. At this time, the gamma
memory data is not writing into the internal RAM but all
graphics/text data will be transferred to the register inside
the device instead.
When adjustment is carried out, adjustment data are
written into the NVM automatically (items on the user
mode) or by the trigger of memory operation (items on the
service mode and special service mode).
Adjustable items (W/B and Device Adjust) of the service
mode and special service are memorized into the NVM by
the memory operation. At the same time, the factory preset
(adjusted) data are all eliminated from the memory.
