Sometimes when you live in apartment or rent a house, the building manager or renter would not like you to open the receiver box to program remote control you bought, because he prefers to sell original remotes at a very high price.
If the receiver’s remote learning function is enabled, then you just got lucky as you can program your new remotes bought somewhere without directly accessing the receiver box.
The procedure is as follows.
1. Transmit the NEW code number by pressing the button on new remote for at least 5 seconds.
And then slowly:
2. Transmit an OLD code number by pressing the button on remote already programmed in 3 times.
3. Transmit the NEW code number once by pressing the button on new remote for 1 seconds and then release to confirm.
If your receiver’s remote learning function is enabled, then you can try press the button on new remote, the door or gate will respond.
