2)  After 8 seconds, the indicator light will turn off, release the learn button. Then codes have been deleted.

Note: Each module will support 30 remotes,  If you teach over 30 remotes. The 31st remote will automatically remove the pairing of the 1st transmitter in the system.

Encoder Type:
These are fixed codes and completed soldered.
Please note that if you are using a transmitter that supports rolling codes such as ET or Centurion remotes, they will not be compatible. This module will only support standard 315Mhz remotes.
