Could someone help me find a good set of definitions that explain what each programing item does. I know many are very self explaining but some I haven't a clue what they might effect.

Is it worth setting up a rad for programing?

I also have a startalk voicemail which I would like to connect. I need info on how to connect and program.

I am having specific trouble with setting up my service modes is the only thing it does is change the answer mode from auto, manuel or off? What are TAFAS? What is the extra dial set?

Thanks
Joe
