★★★★★
I have a Linear gate, a Moore-O-Matic shop opener, and a third receiver on a separate barn. One DT-3 handles all three.

Each button has its own independent 10-switch DIP block — set each one to a different gate or door receiver. Trinary coding gives 59,049 combinations per button (much more secure than binary 9-switch).
Programming the Delta-3 DT-3
Match each button's 10-switch DIP block to its target receiver — no learn-button sequence required.
- Open the back of the DT-3. There are three independent 10-switch DIP banks, one per button.
- For each receiver: set its 10-switch DIP block to match the corresponding button bank.
- Replace covers and test all three buttons. Range will be 100+ feet line-of-sight.
For households with multiple DT-3 fobs sharing one receiver: every fob must use the identical 10-switch pattern on whichever button operates that gate.

★★★★★
Linear visor clip and case quality is a step above every consumer brand. Worth the small premium.
