This Transmitter Solutions Hive garage door replacement radio receiver set includes (1) Hive Single Channel Radio Receiver and (2) Stinger 300MCD21V single button visor remote controls.  This kit is designed for use in residential garage door operator applications. This unit is perfect for retro fit applications where your remotes aren’t working like they once did, but overall, the opener still works great.  Installation in most applications is a simple process, just mount the Hive to the 3 screw terminals on the back of your opener.  Once the receiver is mounted simply set the 10 on/off switches on the remote to match the same settings on the receiver and you’re ready to go.
