Note: In case you did not know the 5200 is a Pronto with more buttons
1) go to the Pronto forum (a lot of help there)
2) look in the Pronto file section (on this site) then pick component CCF, You can find there the codes for a lot more equipment then on the remote
3) read the Pronto FAQ
4) look at the manuals for all remotes in the familly, the remotes are mostly the same, but the manuals are totaly different.
