Compatibility with RF433 Superheterodyne Module?

[mandy]

when you download firmware, need remove the RF receiver module.
if can't learn by KCS firmware, maybe your remote's data code not supportted.

Thanks for the reply. I had installed the firmware first and then connected the RF module. So it wouldn't be a compatibility issue, maybe it's just that the RF transmitter I used for the test is not compatible, as you said. I'll try another one. Thanks!
