This section explains the data streaming simply.
When the projector is turned on, required data for the
current picture, such as status memory data, etc., are se-
lected from the respective memory blocks, and are written
into the internal RAM. 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), then stored them.
Be careful that the factory preset (adjusted) data of the user
adjustable items are all eliminated from the memory when
user performs adjustment of the adjustable items (W/B and
Device Adjust) and the memory operation to memorize the
user adjustment data into the NVM.
* When the power to the projector is turned off without memorizing the
adjustment data, the original factory preset (adjusted) data can be
restored by removing the power cord once and connect it back again.
