User's Manual (detailed)
Instant Stack Guide
Thank you for purchasing this projector.
Features
This projector can be used with another projector of the same model to project an
image on the same screen using the Instant Stack feature.
The two projectors can be operated simultaneously to make the image brighter.
Moreover, if you connect two projectors with RS-232C cross-over cable, it turns
to an intellectual stacking system. The two projectors can work alternately by
themselves, and once one projector has an accident the other voluntarily starts to
work to keep your presentation going.
These features, generically called Instant Stack, provide you with the broad use.
