I don't know and I only tried it on one of my keyboards, which is a

one with some extra keys for the usual stuff, like E-Mail, Search and so

If I turn it upside down there is a label saying "This device comlies

FCC stands for "Federal Communications Commission" a United States
regulatory body in charge of allocating and monitoring radio frequency
spectrum licenses. The label asserts that a sample of the product was
tested and did not radiate radio frequency waves outside the limits.
Sounds a bit strange since the keyboard is NOT wireless... but yes, radio
frequencies can be produced anyway.
Digital circuits, as used in computers, keyboards etc., all generate RF
energy, which has the potential to cause interference. The FCC (in
U.S.) places limits on how much can be radiated, to prevent such
interference.
