SETUP AND INSTALLATION
Remote Control Effective Range
Infra-Red (IR) remote control sensor is located on the top and front sides of the projector. Ensure to hold the
remote control at an angle within 30 degrees 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 20 meters (65.6 feet)
when holding not longer than 30 meters (98.4 feet) when aiming the sensor at 0°.
±
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 projector/remote control is not being shined by sunlight or
fluorescent lamps directly.
±
Please keep the remote controller away from fluorescent lamps for over 2 m 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 5 m 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.
