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 CPU 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, the adjustment data is
stored in the NVM automatically (for items of the user
mode) or by the trigger of memory operation (for items of
the factory mode).
Adjustable items (W/B and Device Adjust) of the factory
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.
