30 degrees 30 degrees 45 degrees 45 degrees Operating the remote control • The remote control works with both the projector's front and rear remote sensors. • The range of the remote sensor on the front is 3 meters with a 90-degree range (45 degrees to the left and right of the remote sensor), and back is 3 meters with a 60-degree range. • Since the remote control uses infrared light to send signals to the projector (Class 1 LED), be sure to use the remote control in an area free from obstacles that could block the remote control's output signal to the projector. ATTENTION Precautions to observe when using the remote control • Do not drop or otherwise expose the remote control to physical impact. • Do not get the remote control wet or place it on wet objects. Doing so may result in malfunction. • Remove the batteries from the remote control and store them in a safe place if you won't be using the remote control for an extended period. • Replace the batteries whenever the remote control starts to malfunction. • When strong light, such as direct sunlight or light from an extremely close range (such as from an inverter fluorescent lamp), hits the projector's remote sensor, the remote control may cease to function. Adjust the direction of the projector to keep light from directly hitting the projector's remote sensor. 13
