    Sony Discman Model NO D-M801:
    "PRODUCT COMPLIES WITH DHHS RULES 21CFR SUBCHAPTER J APPLICABLE, AT DATE
    OF MANUFACTURE."

    and

    "THIS DEVICE COMPLIES WITH PART 15 OF THE FCC RULES. OPERATION IS
    SUBJECT O THE FOLLOWING TWO CONDITIONS: (1) THIS DEVICE MAY NOT CAUSE
    HARMFUL INTERFERENCE, AND (2) THIS DEVICE MUST ACCEPT ANY INTERFERENCE
    RECEIVED, INCLUDING INTERFERENCE THAT MAY CAUSE UNDESIRED OPERATION."

    I don't think that it is a requirement that it must be printed on every
    product, but documentation must come with the product. I don't have any
    label or documentation on my blender or popcorn popper. However, with
    the FCC ID, you are able to find out what you need to know if you are
    willing to look.

    Isn't that a CD Player? Not something that transmits or receives? Is there
    anything in fcc regs that let you transmit whatever you want?

    CD palyer or not, it obvisouly fell under the authority of the FCC. I'm
    willing to bet that many electronics also have stipulations in the same
    way. So, in other words, because a mobile phone is approved for use
    does not guarantee that no interference will happen.

    But some of the people here have stated that since it's FCC approved, it
    will NEVER interfere and that it should be allowed anywhere and everywhere,
    and it's tough if it interferes with someone else, that's their problem, I
    think that selfish/self centered attitude is really rude and wrong, and some
    of the people have stated (not in the following words, but ideas) that so
    what if it someone dies, It's not *my* fault, I can do whatever I want cuz
    my phone is FCC approved and can therefore never do anything wrong.

    It appears that we are both on the same side. I used the "must accept
    interference, including for undesirable operation" as an example that
    even approved products may have interference.

    The "This device complies with Part 15 of the FCC rules." part is, for
    any product that transmits signal in the RF range. The rest is
    inherent, since it's part of Part 15.

    >I don't have any label or documentation on my blender or popcorn popper.


    Motors are exempt even though they're pretty good spark transmitters.

    Yes.

    No.

    CD players transmit signals and are subject to interference from
    transmitted signals. Most electronic devices fall into that class.
    If there's a timing signal in the device (like a CPU clock), it
    transmits signal. And you know that computer monitors and speakers
    are subject to interference from TDMA phones, among other things.

    > Is there anything in fcc regs that let you transmit whatever you want?


    As far as?

    You can't transmit more than a certain power level at most
    frequencies. You can't transmit anything illegal (treason, plans to
    commit a felony, etc.) You can't deliberately interfere with another
    service. Things like that. But you can run your own radio or TV
    station if the power level is low enough.

    Then why do I periodically hear "bzzt bzzt bzzt bzzt" burping sounds from
    my Radio Shack dual trunking scanner and from my computer speakers when
    they are close to my Verizon phone?

    ...... One day after posting this, I got scanner-related spam, which I've
    never gotten before.
