3.4 White balance
Note:
ü
The cut point doesn’t need adjustment, because it’s automatically made by the
IC101.

The white adjustment is already pre-adjusted and incised in the IC101 and,
thus, its adjustment is not necessary.
Otherwise, if it is necessary to change the temperature of the white pattern, proceed in the
following way:
a) Enter in the service mode.
