Instructions are not great but if you solder two wires and different locations you can make it through various things with the relay make sure you have an OHM meter when you're playing with it but anybody with simple electronic knowledge should be able to figure it out, I will buy another one Review: Works well, tiny receiver. - Good news - the receiver is tiny and has SPDT relay output, bad news the receiver is tiny, changing operating mode requires skill with SMD in tiny spaces. Excellent range. Reliable operation. No documentation to explain "learn" feature, had to re-solder the code jumpers on a spare transmitter to get it to work with the original receiver. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B078RFJTMZ | | Batteries | 1 9V batteries required.

Instructions are not great but if you solder two wires and different locations you can make it through various things with the relay make sure you have an OHM meter when you're playing with it but anybody with simple electronic knowledge should be able to figure it out, I will buy another one ### ⭐⭐⭐⭐ Works well, tiny receiver. *by A***R on October 20, 2018* Good news - the receiver is tiny and has SPDT relay output, bad news the receiver is tiny, changing operating mode requires skill with SMD in tiny spaces. Excellent range. Reliable operation. No documentation to explain "learn" feature, had to re-solder the code jumpers on a spare transmitter to get it to work with the original receiver. ### ⭐⭐⭐⭐⭐ Works perfectly for a on off application. *by A***R on January 24, 2020* Wired it into a remote generator about 400 feet from my shop to cycle for heavy loads. Works perfect! The receiver is a small delicate thing about the size of your thumb so you need to mount and protect it. Instructions are weak but four wires are easy to identify. I don't have to raise the antenna on the remote, it just does the trick.
