The BenQ Remote Control is a replacement for the one which ships with the MS513, MX514 and the MW516 digital projectors. This IR unit controls most functions of the above projectors.
The remote control must be held at an angle within 15 degrees perpendicular to the projector's IR remote control sensor to function correctly
The distance between the remote control and the sensor should not exceed 26' (8 m).
Infra-red remote control sensors are located on the front of the projectors
