<ENTER> button.
5) Set [SUBNET MASK] and [IP ADDRESS] in each projector.
f To be able to communicate over the network, set the same value in [SUBNET MASK] for all projectors and

6) Wait for at least eight minutes after starting projection until the lamp brightness becomes steady.
7) Set all items in the [PICTURE] menu of all projectors to the same values.
8) Adjust [COLOR MATCHING] to match colors.
9) Display the internal test pattern “All white” in all projectors.

projector of which [BRIGHTNESS CONTROL GAIN] is set to 90 %.
13) Set [MODE] of [BRIGHTNESS CONTROL SETUP] to [AUTO], and [LINK] to [GROUP A] on all
projectors.
14) Select [APPLY] of [BRIGHTNESS CONTROL SETUP] and press the <ENTER> button in all projectors.
