    Remote control effective range
    Infra-Red (IR) remote control sensor is located on the front of the projector. The 
    remote control must be held at an angle within 30 degrees perpendicular to the 
    projectors IR remote control sensor to function correctly. The distance between 
    the remote control and the sensor should not exceed 8 meters (~ 26 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.
    • Do not let the IR transmitter of the remote control be 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
