XG-C435X/C465X

3 – 9

The following measurement and adjustment must be performed under the same conditions using the following:

• Dark room (Block out stray light.)

• Diffuse reflection (mat type) screen

The setting of the projector must be performed under the following conditions:

• Power save disabled (to keep the lamp stable during measurement)

• Auto search canceled (to fix to INPUT1)

• RGB mode of the input terminal COMPUTER1 (component mode canceled - just to be sure)

1. System setting (“Setting -” System setting””)

Condition setting for C435/C465

2. Teaching

Basically, teaching should be measured only once from model to model. However, if the optical characteristics of the set are changed significantly,
it is necessary to reset the conditions according to changes and to perform remeasurement.

Measurement method of correction factor

1) Determine the standard set of C435/C465. Each one unit (n units)

2) Switch the set to the RGB mode of the input terminal COMPUTER1.

3) Execute teaching of the standard set under the following conditions.
