Gamma memory is actualized through Gamma mode
functions'offsetting the output values to the Contrast and
Brightness devices.
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.
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), then stored them.
Adjustable items (W/B and Device Adjust) of the service
mode and special service mode are memorized into the
NVM by the memory operation. At the same time, the
factory preset (adjusted) data are all eliminated from the
memory.
