Old Electronics Identification

Feb 04, 2004 3 Replies

Hello! While digging through my Dad's old stuff I found an odd little device. Amazingly, after who knows how many years, the battery still worked! Its some sort of tone-generator, and I'm curious about what the heck it'd be used for. The only markings on it say "Sanyo RC-555B", but that hasnt gotten me anywhere so far. Heres a picture and an mp3 of the sound it makes:

If it helps, my Dad worked in telecommunications. Thanks for any information!

It sounds like "ring" to me ;-)

I have a similar looking device around here somewhere that could generate touch-tone signals acoustically.

While contracting at Honeywell I needed to make personal-business calls, but their digital switchboard couldn't handle my dialing to my own long-distance provider and then keying in the number I wanted to reach.

So I dialed my provider, then used the tone generator to complete the call.

Probably a remote control for a telephone answering machine.

Hmm, he did have an old answering machione laying around. It's quite possible that it was a Sanyo also. Unfortunately, it's long gone.

Well, if thats what it is, thats pretty boring. :) I didnt realize such things existed, but you're probably right.

Thanks! Joe
