SETUP AND INSTALLATION Effective range Infra-Red (IR) remote control sensor is located on top of the projector. Ensure to hold the remote control at an angle within 30° (horizontally) or 20° (vertically) perpendicular to the projector's IR remote control sensor to function correctly. The distance between the remote control and the sensor should not be longer than 7 meters (~22 feet). Note: When pointing the remote control directly (0 degrees angle) on the IR sensor, the distance between the remote control and the sensor should not be longer than 10 meters (~32 feet). ‡‡ Make sure that there are no obstacles between the remote control and the IR sensor on the projector that might obstruct the infra-red beam. ‡‡ Make sure the IR transmitter of the remote control is not being shined by sunlight or fluorescent lamps directly. ‡‡ Please keep the remote controller away from fluorescent lamps for over 2 meters or the remote controller might become malfunction. ‡‡ If the remote control is close to Inverter-Type fluorescent lamps, it might become ineffective from time to time. ‡‡ If the remote control and the projector are within a very short distance, the remote control might become ineffective. ‡‡ When you aim at the screen, the effective distance is less than 7 meters from the remote control to the screen and reflecting the IR beams back to the projector. However, the effective range might change according to screens.
