Hello. I have here a GR300 repeater patch (Zetron 48jr) that I am trying to re-program. Does anyone have a spec sheet/programming sheet as how to program via DTMF tones with a radio on the repeater's frequency?

Thanks,
Ray.

Spec Sheet

Thanks for the reply. I am looking for the access digits to the controller on how to enter programming mode, I have tried DTMF 12123, but with no luck. The manaual does not state as how to enter. Is there a DTMF Code I can use to reset the controller? Currently if I hook it up to a phone line, I can dial the access code written on a sticker on top to get a dial tone, and # will close the connection.

But that's as far as I've been able to go.

I've got a programing book on that back at the bench at work I think. I'll see if I can scrounge it up for you. As I recall the default access code os something like XXX48. I know the last digits is the model.

Did you get it yet Ray?

I'm planning on going to the provinces radio shop friday, so I can *probably* find out if you didn't figure it out...

Nah, didn't get it just yet. Again, I can open and bring up autopatch (*051), but other than that, *12123 doesn't even work, so, I am clueless thus far. Let me know watcha find.

OK, I checked and I don't have it but I'm pretty sure that the last 3 digits are 048.

You might try calling Zetron.
