This B&D garage door two-channel transmitter is often used for residential block of units. One button controls the public main entry door while the other button controls a private garage door. Suitable for the following openers:
B&D Controll-A-Door 4 (CAD4)
B&D Controll-A-Door 5 (CAD5)
B&D Controll-A-Door P (CADP)
B&D Controll-A-Door R (CADR)
This remote control has been discontinued and replaced by CAD605C.
Please note for CAD603, the ribbed button is on the right which is different from CAD227 where the ribbed button is on the left. These two remotes have totally different upgrade solutions so please do distinguish before purchase.
The coding of the original remote, i.e. the combination of the positions of the dip switches, needs to be replicated it into the new remote. As a result, you can use it straight away without program.
This one has been upgraded to CAD605C.
