I am a certified electrician, retired.
The directions seem 2 B straight forward. However the key fob tht contains the battery is a bear to try to open to check to see if the battery is working by replacing it with a new CR2032. I M 81 yrs of age and I cannot get the battery compartment to open. It's not a simple case of sliding the drawer contining the battery open. It's kid proof, plastic, frustrating!! WHAT I READ IN THE ONLINE DESCRIPTION is that this remote operation! Forget that!! IT HAS A LIGHT SENSOR FOR CONVENIENCE??? The Receiver is plugged into an outdoor recepticle with GFCI that works perfectly okay with my outdoor lights. I wanted to add a remote so that I don't have to step out onto my balcony when it's snowing and blowing!! IT OPERATES ON A LIGHT SENSOR!! WHEN IT'S DUSK, THE LIGHTS WILL GO ON. if I wanted a solar on/off I would have bought one, which are useless as we have outdoor lights in our parking lot that confuse the solar sensor into thinking it's day. I will be returning this item.
