Myst Island -- The imager

The imager is a machine that is used to display messages and information. Is there anything else in this room?

In the note left for Catherine from Atrus, it said to enter the number of marker switches on the island.

Hold it! Where is the imager?

I only see one image, how can I see more?

I enter the number of marker switches, but I don't get any message.
