Slide the remote cover open or remove the screw. Replace the old battery with a new CR2032 lithium cell, ensuring correct polarity. Close the cover and test the remote.

Lubricate the belt drive annually with a silicone-based lubricant. Avoid using grease as it can attract dirt.

Press and hold the Learn button on the motor unit for about 6 seconds until the LED turns off. This clears all remotes and keypads.
