My pool light won't turn on:

• Check the GFI on the plug outlet at the pool equipment. Push the reset button in. Nearby lighting or static charges can trip this button. There is a plastic piece under the button called a slide bar. 
• Make sure it is all the way over to the right. Make sure the batteries in your remote control are in correctly and charged. 
• Turn the light on at the manual switch at the equipment. This switch has a square push button. 
• Check the breaker in the electric panel.

My pool light turns itself on and/or off by itself:

Your remote control is subject to interference from a variety of sources. Garage door openers, household appliances, house intercoms, phone company microwaves and neighbors with their own remotes can interfere with your remote. Usually, changing the frequency of your remote will correct this interference. 

Turn the dial on the face of your hand remote to another letter. Make sure the dial on your plug in remote (if you have one) matches the same setting. Also, change the dial on the light module at the pool equipment location to match the settings on your remotes. To locate the module, look for the electrical device that has the square button that manually turns the light off and on. If you cannot see the red dial (matching the one on your remote) on the face of the module you will have to remove the cover plate that is concealing it. Change the dial so the letter matches the one you selected on your remote. You may have to try a number of different settings if your first attempt isn't successful. Example: if you set the dial on your remote to point to the letter "C", then the dial on the module also must point to "C".
