Introduction
Battery Installation
Remote Control Precautions
• Handle the remote control carefully.
• If the remote control gets wet, wipe it dry immediately.
• Avoid excessive heat and humidity.
• Do not place the battery upside down.
• Replace only with the same or equivalent type recommended by the manufacturer.
• Dispose of used batteries according to your local regulations.
1. Press firmly and slide the battery cover off.
2.  Install new batteries (AAA). 
Ensure that you have the 
batteries’ polarity (+/–) 
aligned correctly.
3.  Slip the cover back over the 
batteries until it snaps into 
place. Do not mix different 
types of batteries or new and 
old batteries.	The infrared signal operates by line-of-sight up to a distance of about 22 feet/7 m and within a 60-degree angle of the remote sensor on the projector cabinet.
	The projector will not respond if there are objects between the remote control and the sensor, or if strong light falls on the sensor. Weak batteries will also prevent the remote control from properly operating the projector.
