LASER POINTER, PEN,
AND LED LIGHT

Laser Pointer, Pen, and LED Light, retail $TBA
Manufactured by (Unknown)
Last updated 08-30-09




This is a 3-way device that has the following functions:
  1. Blue LED flashlight
  2. Red laser pointer
  3. Ballpoint pen
It comes in an all-metal body, operates from three AG13 button cells, and has a ballpoint pen that operates regardless of the batteries' State of Euphoria - er - uh - state of discharge (there I go thinking about the heavy metal band Anthrax again!!!).



SIZE



To use the pen, grasp the unit at each end, and give a gentle clockwise twist.
Write.
When finished, perform the same action as above, but twist conterclockwise instead. Don't twist too hard here, or you'll start to unscrew the pen itself and you'll run the risk of having those little itty bitty button cells fall out and clatter all over the floor.

To use the LED, press the lower button on the barrel and hold it in to turn it on; release the button to turn it off.

To use the laser, press the upper button on the barrel and hold it in to turn it on; release the button to turn it off.

This instrument comes with a pocket clip, allowing you to carry it clipped into a shirt or pants pocket, reducing the chance that you'll lose it when carried that way.



To change the batteries in your Laser Pointer, Pen, and LED Light, grasp the unit at each end, and unscrew the two halves until they come apart, then dump the dead batteries out of the upper portion of the product. Dispose of or recycle them as you see fit.

Drop three new AG13 button cells into the barrel, button-end (-) negative first, and then screw the "business-end" back on.

Alternately, stack the cells on a table flat-end (+) positive down, lower the barrel of the light over them, then pinch it off with your finger while picking the light up so the batteries don't fall out. Then screw the "business-end" back on. Many button cell lights and other products powered with button cells are prone to having cells go in cockeyed; this is one way to avoid that.

Unable to measure current due to how the product was constructed.


Eventually, you'll need to change the pen refill.
I do not know what type or model pen refill this is, so please do not ask.



This instrument is reasonably durable, but because it has a laser in it, I won't do the smack test on it. I know you love to see me break things, but it "ain't" "gonna" happen today, folks.

Water-resistance is minimal at best. When the business-end was suctioned, air had no problems whatsoever passing through it. So please try not to drop it in creeks, rivers, ponds, lakes, oceansides, docksides, puddles of siamese cat pee (what - no plastic cat toilet (litter box)?), slush piles, mud puddles, tubs, toilet bowls, cisterns, sinks, fishtanks, dog water dishes, or other places where water or water-like liquids might be found.

If it fell in water and you suspect it got flooded, disassemble it as you would for a battery change, dump out the water if necessary, and set the parts in a warm dry place for a day or so just to be sure it's completely dry inside before you reassemble and use it again.

If it fell into seawater, got thrown into a glass of milk, if it fell in a root beer float, if it fell into a bowl of "soft-serv" ice cream, if somebody squirted a Massengill brand post-menstrual disposable douche or a Fleet brand disposable enema at it (and hit it with the douche or the enema), or if somebody or something got "pist off" at it and subsequently "pyst" on it, rinse the parts out with fresh water before setting them out to dry. You don't want your "Laser Pointer, Pen, and LED Light" to smell like seaweed, sour milk, flowers, fresh butts, or rotten pee when you go to use it next. Besides, salt (from seawater, disposable douches, disposable enemas, or uranation), lactic acid (from moo juice), glycerol (from antifreeze), or sugar (from root beer & ice cream) can't be very good for the insides.

The ballpoint pen portion writes in black ink; and has the writing quality of a very good disposable.

TEST NOTES:
Product was found in a box on 08-27-09; I believe it was purchased on Ebay sometime in mid- to late-2004 but certainly no later than early-2005.
