Old Electronics Identification

[Joe Bott]

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.

I love to cook with wine. Sometimes I even put it in the food.

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!
