Notes for the Remote Control Unit

• Be sure to insert the batteries in the corresponding orientations to match the polarities.
• Do not mix new batteries with used batteries as it would shorten the life of new batteries or cause leakage.
• Only used AAA batteries as instructed; do not attempt to insert different types of batteries into the remote control.
• If the remote is going to be unused for long periods of time, be sure to remove the batteries to prevent leakage, which could damage the remote control.
• The liquid contents in the batteries is harmful to the skin; do not touch the leakage with your bare hands directly. When installing fresh batteries, be sure to clean up the leakage thoroughly.
• Under most circumstances, you only need to point the remote control towards the screen and the IR signal would be reflected off the screen and picked up by the IR sensor on the projector. But under specific circumstances, the projector may fail to receive signals from the remote control due to environmental factors. When this happens, orient the remote control at the projector and try again.
• If the range of effective remote control signal reception decreases or if the remote control stops working, replace the batteries.
• If the infrared receiver is exposed to fluorescent lamp or strong sunlight, the remote control may not operate normally.
• Refer to the regulations enforced by your local government on the disposal of used batteries; improper disposal could damage the environment.
