Anyone have a schematic for a RELM RH256NB?

Any idea what the "N" in the model is? I have the schematic for the RH256, and I would assume that it is either the same or so close that it will work. Let me know how large a file your ISP will let you have in your inbox, and I'll get it to you.

There are two versions of the N models. The circuit boards are different. I can look up something for you. The prefix number of the serial number tells which manual to use. The N models are the later models and can be computer programed.

With that being the case, I doubt if the original schematic would be of much use. However, I'll still sent it if its wanted.

Redbird:

I need the schematic and parts layout for the RH256NB. Can you scan them and email to me? Or will pay you to copy and send to me by mail. I have contacted Relm and all their dealers. Relm says the manual is no longer available at any price and they do not even have one they can copy a few pages for me.

Hey all, I just came across an old RH256NB serial number 681-A23702. I contacted Relm back at the beginning of July and they told me TWICE that they were mailing me an owners manual. Well I still do not have it. I have not been able to program this either as it doesn't have the "programming" switch all the instructions I have found online are talking about. The unit does power up and I'd really like to be able to use it.

Does anyone have a copy of the owners manual and have any idea what I have to do to be able to program this unit???

Thanks

I guess by now you have cleaned the on off switch?
