This is a sync kit which can upgrade all B&D Control a Door 4 series remote controls to clean design, light and small remotes.
Installation of the receiver couldn't be easier. Just hook up the three wires onto your opener as shown in the diagram below. Then it's done! The new remotes have been pre-programmed so you can use them straight away! And, your existing remote will still work, no conflict with the new ones.
If you need an extra remote, click MK300, the new receiver holds up to 30 remotes, more than enough!
It's also avaible MK602.
