SETUP AND INSTALLATION
Effective range
The Infra-Red (IR) remote control sensors are located on the front and top sides of the projector. To have the
remote control function correctly, be sure to hold the remote control at an angle of ±30° horizontally or vertically
within the distance of 10m (32.8 ft) to the projector's IR remote control sensor.
‡ Make sure that there are no obstacles between the remote control and the IR sensor on the projector.
‡ Make sure the IR transmitter of the remote control is not being obstructed by direct light from sunlight
or fluorescent lamps.
‡ Keep the remote control away from fluorescent lamps for at least 2m or it may malfunction.
‡ If the remote control is near Inverter-Type fluorescent lamps, it may operate ineffectively at times.
‡ If the remote control and the projector are within a very short distance, it may operate ineffectively.
‡ When aiming at a screen, the effective distance is less than 5m from the remote control to the screen
and reflects the IR beams back to the projector. However, the effective range may vary between
screens.
