The MWR12 receiver is designed to receive information from the transmitter and relay it to the motor to stop or reverse motion if the edge comes into contact with an obstruction.
Note: Only the far right of the three buttons (1 dot button) will operate those older Genie Intellicode units built from 1995 through 1997.
If you have a Genie unit built in 1995 1996 or 1997 this is the only remote that Genie presently makes to operate the Genie garage door openers built during these years.
In this special case the remotes can only be used as 1 button remotes and no other multi-button Genie remote is compatible.
