adjustable feet. The adjustable feet can also be used to adjust the projector to be level when it is tilted in the
horizontal direction.
Extend the adjustable feet by rotating in the direction shown in the gure and retract by rotating in the opposite
direction.
Maximum adjustable range
Adjustable feet: 23 mm (29/32") each
