the direction of the arrow to remove it.
2. Install two AAA batteries with the
correct polarity.
3. Replace the cover.
Notes on Batteries• Make sure that the battery polarities are correct when installing the batteries.
• Do not mix an old battery with a new one or different types of batteries.
• If you will not use the remote control for a long time, remove the batteries to avoid
damage from battery leakage.
Notes on Remote Control
Operation
• Make sure that there is nothing obstructing the infrared beam between the remote
control and the IR receiver on the projector.
• If the effective range of the remote control decreases, or it stops working, replace the
batteries with new ones.
• The remote control may fail to operate if the infrared remote sensor is exposed to bright
sunlight or fluorescent lighting.
• Ambient conditions may possibly impede the operation of the remote control. If this
happens, point the remote control at the projector, and repeat the operation.
