it doesn’t seem to sync up with the remotes…
I’m afraid not…
Our C-SP-315 works only with 315Mhz Security+ coding (aka. Liftmaster/Chamberlain purple learn button ones).
C(Compatible)-SP(Security Plus)-315(Mhz).
And C-SP-390 works only with 390Mhz Security+ coding (aka. Liftmaster/Chamberlain red/orange learn button ones).
Genie, however, is using their own Intellicode coding, thus not compatible.
Please let me know if you have other questions, thanks.
If your door is Genie opener, please just visit Amazon returns center to proceed with return & refund.
