This remote replaces Dominator DOM501 and DOM502. It's a genuine Dominator product.
The programming of this upgraded remote is slightly complicated, so setup follow the instruction step by step, be careful not to do it too fast or too slow.
If you find yourself a bit lost in the complicated programming, consider the conversion kit MK701 (one receriver plus one remote) or MK702 (one receiver plus two remotes). Same price but much easier to use.
No need to keep pressing various buttons like playing piano but simply hook the three wires of the receiver to your Dominator opener, then the remote will work! We have pre-programed the consersion kit for you.
The MK701/702 receiver accommodates up to 30 remote controls and your existing DOM501 remote will still work.
