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 ... ?

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

BTW:

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

** 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...

Well, yes, I suppose there is an *indicator* LED, but just the one, and it's
hidden behind a coloured insert in the front panel, that surrounds a button
assembly. I suppose if you are being really precise, there is a LED in the
Toslink socket on the back as well, but then just about every piece of
consumer electronics in existence now, has an indicator LED, and a Toslink
socket or two on the back, and I've never seen any other item carry a
similar statement about LEDs and classes. And to Mark, it's not a more
accurate statement regarding a semiconductor laser in this case, because
there's not one in it. No optical drive of any description. It's just a
cable set top box with an HDD in it for recording.

Hi!

That is what I think they're talking about. I've seen that warning in
some CD player owner's manuals, and every one of them had an optical
digital output.

This LED seems rather bright. I've noticed that it casts a bright
circle on the wall behind the player--yes, one of mine is missing the
dust cap. Maybe it's on the verge of being harmful if you were to look
into it or something?

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

Does it by any chance have a TOSLINK output, for providing digital-audio
signals to an A/V receiver/amplifier? A lot of STBs do, these days,
and this might require the Class 1 label.

The Classes assigned to laser products for eye safety are now being applied
to LEDs. I got a replacement 12V Outdoor Lighting Transformer that stated
it can not be used on Class II LED Products. That prompted me to look into
this issue recently. :)

Anybody know how to locate and power up a computer, open a web browser,
get to google.com and arrive at a clever search string like "Class 1 LED
Product"?

No. Is that possible?

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

Doesn't microsoft have a warning "this browser is shit, using it may

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).
