Carrier frequency on a Checkmate IV (RT-U49C) remote?

[[email protected]]

Would anybody know what the carrier frequency the Checkmate IV (model
#: RT-U49C) remote uses? I think they are manufactured by a company
called Contec.

Would it be around 40khz or so? Is there any online resource that would
be able to tell me definitively?

Thanks in advance.

Is it RF or IR?

Given all of the AV devices it has codes for it's probably IR and probably
in the 38-40kHz range since this is what _most_ AV gear uses.
