I have been trying to reprogram our TK-780 that serves as a base radio. We used
to have it setup to trigger a light relay using the horn alert feature but when
the radio service people came to add a channel, they messed it up. I am using
KPG49D v4.01 and can read the radio fine, but when I go to program it I get an
error that it is not a 2.0 Production Radio. So I tried using KPG49D v3.02 and
when I go to program it, I get a similar error about it not being a production
2.0 radio and 2.0 features will not be programmed. What are the 2.0 features?
All we want is to be able to have the horn alert function work again. Should I
write to the radio anyway? I'm just nervous about screwing it up.

Thanks!
