Notes on Remote Control Operation

Make sure that there are no obstacles between the remote control and the IR sensors on the projector that might obstruct the infra-red beam.

10 Introduction

Remote Control Effective Range

Infra Red (IR) remote control sensors are located on the front and the back of the projector. The remote control must be held at an angle within 30 degrees of the projector’s IR remote control sensors to function correctly. The distance between the remote control and the sensors should not exceed 6 meters (19.5 feet).

6m

Warning Messages on the Back of the Remote Control

The laser beam is visible. It is necessary to depress the Laser button for continuous output.

The laser pointer is not a toy. Parents should be mindful of the dangers of laser energy and keep this remote control out of the reach of children.
