This is a commercial radio and often, the programming for the is not as easy as with an Amateur radio. I haven't worked on this radio specifically, but I do remember with the commercial radios that I repaired that often there was a jumper that had to be removed or installed to be able to program them. This prevented the customer from getting into the programming and screwing things up, plus it is ******* for them to do this unless they are licensed to work on commercial radios. My guess is you have to find out if this is in fact the case. A good place to look for radio manuals is www.mods.dk.
