This remote control is labeled with D.O.C. SPEC:RB214A, 318 MHz - TX318 inside, which has been obsolete. It has been replaced by MPC2 FOB, which has same frequency and code set with 9 dip switches, and light in weight and small in size.
To program, simply march 9 switch with your original remote.
If you do not have a original one , just follow instruction. it couldn't be easier.
Some remotes with 4 buttons don't have the 9 DIP switch that means it has a fixed code only and also poses safety risk.

This one is upgraded to MPC2 FOB.
