Welcome to the phorum.

I've not set them on that model but there is a service bulletin #398 that has some info.  The link to a djvu version is HERE.  the site also has a link to download a browser helper to open djvu documents.   There are specific frequency ranges for each of the 5 broadcast pushbuttons so there has to be a good am station in each of the ranges to get something on all of them.  its also possible that the coil in the button circuit has broken and that would kill that button.

UPDATE: Here's a direct link to the pdf version of the service bulletin: LINK
Cheers,
Bob
