What on earth is a "Class 1 LED Product" ??

    Today, I had occasion to look at a set top box for cable TV service. It's a
    HDD recorder as well, employing what seems to be a standard computer disc
    drive. When I came to screw the lid back on, I noticed on the back panel,
    the words "Class 1 LED Product". What on earth do they mean by that ? I've
    seen similar statements for laser-based products such as CD players or DVD
    players / recorders, but in those cases, it is a warning. I'm not even sure
    that this unit has any LEDs in it, so in this case, does the word "LED"
    refer to something else ? What are Samsung (the makers of this box) trying
    to tell (warn??) us of here ... ?

    ** Means inherently safe in normal use.

    ** No, class 1 LASER products are inherently safe in normal use too.

    http://en.wikipedia.org/wiki/Laser_safety#Class_1

    BTW:

    The Sony CDP101 was described in the manual as having a class IIIb laser.


    > I'm not even sure that this unit has any LEDs in it,



    ** What about the remote ??

    Could it be compatible with fiber cable, bi-directional (and therefore
    have a LED (laser)?

    I think it's just a rewording of the old "Class 1 Laser" warning, with the
    laser diode being the LED here. Probably a more accurate description,
    really...

    ** Hard to believe there is not even one indicator LED.

    LED Laser? Lost in the translation? I've seen some pretty weird
    translations in my time as you most certainly have.

    No. Is that possible?

    Do I need to wear any special protection while doing that?

    Well, that's kinda true: pressing <ESC> at any prompt is kinda like
    voting "no" on all ballot propositions (we get a lot of 'em here in
    Kal-ee-fonia).
