To mount the projector on a tripod
The projector includes standard tripod mount on the bottom of the projector. This 
allows the projector to be mounted on tripods readily available at camera and other 
electronic stores.
ÄCAUTION: 
■The tripod should be capable of supporting a weight of at least 5 lb. Refer to the 
owner’s manual that came with your tripod for more information.
■Do not overtighten the tripod mount screw. Doing so could strip the screw and 
cause the projector to fall off the tripod.
To loc k t he  proj ec tor
The projector includes a built-in slot to secure the projector with a cable and a lock 
(such as the Kensington MicroSaver lock system, available at many computer stores).
1. Wrap the cable around a secure object, such as a table leg. Loop the cable to create 
a slip knot around the stationary object, and be sure it cannot slip off.
2. Insert the lock 
1 into the hole and twist the key 2.
