Linear DT1 Gate Remote Control 1-Button

The DT-1 remote is compatible with the Linear Delta-3 receivers only. You would need to check the model on your radio receiver. Or if you have an existing remote that has a model then it would be the exact match of that. If you need to access the receiver, it will be inside the CSW operator. Remove the front panel and you will see the main board with all the accessories wired to the board.
