 Welcome! The following video will demonstrate how to insert and replace the batteries for a 2GB passive infrared motion detector. Begin by removing the screw from the PIR case bottom, then remove the back plate using a bottom-to-top lifting motion. Remove and dispose of the old batteries according to the battery manufacturer instructions and your local regulations. Then insert the new battery. Always make sure you match the plus sign on the battery with the flat side of the compartment and the minus side on the battery with the spring side. Warning! Failure to follow these warnings and instructions can lead to heat generation, rupture, leakage, explosion, fire, or other injury or damage. Do not insert the battery into the compartment in the wrong direction. Always replace the battery with the same or equivalent type. Never recharge or disassemble the battery. Never place the battery in fire or water. Always keep batteries away from small children and if batteries are swallowed, promptly see a doctor. Once you finish inserting the battery, reattach the motion detector to its back plate. Then reinsert the screw at the bottom of the PIR case. The 2GB passive infrared motion detector batteries have now been replaced.
