3. Bit Value Discrimination
Bit values must be discriminated using the display data of the
adjustment remote commander for the following items. Us the table
below to discriminate if the bit value is “1” or “0”.

below to discriminate if the bit value is “1” or “0”.
(Example)
If the remote commander display is “8E”, bit value from bit
7 to bit 4 can be discriminated from the column A, and
those from bit 3 to bit 0 from column B.
7 to bit 4 can be discriminated from the column A, and
those from bit 3 to bit 0 from column B.
