Sentry RMc10. I don't know how to do the code search or perhaps I should say I don't know how to

Question

I don't know how to do the code search or perhaps I should say I don't know how to use this remote I received for Christmas. It did not come with instructions and I don't seem to be able to find and download it instructions. Please help. Thanks. Jerry WyattDITTO for me on having difficulties programming the Sentry Really Big Universal Remote RMC10. For those of you missing the remote manual ... it's very 'tiny' (4"x2") for such a 'big' remote and the print is smaller than a phone book! I needed to write the instructions and codes for my devices down by hand so I could follow the sequence to find the codes. I still haven't got it working for any of my entertainment components. My cable box says Scientific Atlanta so I don't know what 'name' brand that translates to either.
