* The gamma memory is realized by giving offset to Contrast and Brightness output values to the devices in the gamma mode function.
Flow of data is described briefly. When the power plug is connected to the wall outlet for the first time
(Standby state), all data that are stored in the internal ROM are written in the NVM(non-volatile memo-
ry). When the POWER is turned ON, all the status memory data and other memory data that are required
for the present picture are selected from each memory block and expanded in the internal RAM.
When any adjustment is performed at this moment, the adjustment data (user mode items) are written in
the NVM (Service/Special Service item) automatically triggered by the memory operation.
The adjustment items (W/B, Device Adjust) that can be adjusted in the Service Mode or in the Special
Service Mode, are memorized in the NVM at the time when the user performs adjustment and performs
the memory operation. Note that the factory adjustment data will be lost at this moment.
