RDM logo usage

[dsicon]

Hello, i am new here, first post
I have designed some boards that are hardware ready for RDM,
i would like to use the RDM logo with the word "ready" or something similar which i understand doesn't mean a heck of a lot

the marking would be on the pcbs and would be largely a frivolous effort as nobody will see them or care, the boards are internal to gear and not offered for sale on their own

i intend to register our company and get an ID

so my question is this:
are there restrictions or qualifications on the use of the official logo ?

is it ok to add "ready" or is there some other mark that indicates that ?
