    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.

    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
