and changing [POSITION] as 1, 2, and 3 back and
forth to the place where to adjust uniformity.
5. Moving [R] and [B] up and down, achieve its unifor-

the Factory data.

MEMORY, data will not return to the default, unable
Factory to adjust.
Therefore, when saving data after any adjusting
performances, take full care of observation on the
screen.

2-9. Memory

This model is composed of the following six Memory
blocks.
1. Set memory.
2. Status memory.
3. Channel memory.
4. Chroma memory.
5. W/B memory.
6. Installation memory.
Gamma memory is realized in the gamma mode added by
OFF SET function of the Contrast / Brightness output
value to each device.
For your reference, data stream will be briefed as the
follows.
When plugged in first (Standby state), whole data in the
ROM are written in the NVM (Non volatile memory).
Turning Power to ON, memory data required enough for
current video image are selected from each Memory block
and developed in the RAM where adjusting is performed.
Thus, data adjusted in the RAM are written and memorized
in the NVM, automatically when in the user mode, or
triggered by memory operation.
W / B and Device Adjust is adjusted by an user in the
factory mode and memorized in NVM at performing
memory operation. In this moment any data adjusted in the
factory will be lost.
