ABOUT GEMINI

The Stewart Filmscreen Gemini is a custom projection screen product  It contains 2 indivdual screens in 
one housing  One important cautionary note about this product is that it is not advisable to deploy both 
screens at the same time  This screen operation method will protect the back screen from receiving 
strike marks from the front screen in the event of the front screen colliding into or contacting the back 
screen  We strongly urge that you adhere to this advisement to preserve the optical integrity of the back 
screen   The onboard control system contains the Stewart Dual IMC set  It provides the ability to connect 
to any type of switching apparatus to control the screens   

IMPORTANT SAFETY INFORMATION 

Carefully read all instructions  This screen must be installed by a qualified electrician  For supply 
connections, use wires rated for at least 75 C  Use copper or aluminum conductors  For indoor use only  
Do not connect low-voltage to line-voltage power 

Check with your local electrical inspector for compliance with local / national codes and wiring practices   
Earth / ground terminal connection must be made as shown in wiring diagrams  Proper short-circuit 
and overload protection must be provided at the circuit breaker distribution panel  You can use a 20A 
maximum circuit breaker which is typically found in most residential and commercial sites
