2. The way of output

A. Signal keeps 3 seconds-- “1” connect

B. Signal self-locking -- “2” connect

C. Signal interlock -- “3” connect

D. Signal point start--disconnect

（check the Circuit diagram for details）

3. Learning way and steps

1. Press learning key of receiver—the pilot lamp light—release learning key and pilot lamp extinguish , indicate enter into the status of learning. 

2. Press any button of the remote control, indicate learning success as the pilot lamp flash 5 times and automatically exit learning state. Receiver automatically exit learning state if you do nothing in 32 seconds.

4. Delete memory message

Press the learning key of the receiver—pilot lamp light—hold on pressing over 8 seconds until the pilot lamp extinguish, which indict success to delete the memory message.
