I made this Instructional video to help explain how this RF unit works.
2. The way of output
A. Signal self-locking -- “3”, “4” connect
B. Signal interlock -- “1”, “2” connect
C. Signal point start--disconnect
（check the Circuit diagram for details）
3. Learning way and steps
1. Press learning key of receiver—green lamp flash one time —then receiver into the status of learning.
2. Press any button of the remote control, indicate learning success as the pilot lamp flash 1 time. Receiver automatically exit learning state if you do nothing in 32 seconds.
4. Delete memory message
Hold on pressing learning key for 3 seconds until the pilot lamp extinguish then glows, which indict success to delete the memory message.
