Nearly everyone has a cell phone with a camera nowadays -- put your cell
phone in 'photo' mode and look at the IR emitter with it.  You should see a
WHITE light emit from the IR section as seen with the camera's viewfinder.
 Test it with a 'regular' remote control to see what to look for, then test
your IR blaster.

And if your IR emitter looks like this:

...then I've found the IR to be emitted out the 'fatter' end of the emitter,
and in one case it was so weak that I had to tape a small piece of paper at
a 45 degree angle on the end to reflect the IR signal into the receiver.
 (Something like this:   /===   - Where the / represents the paper
reflector, and === represents the emitter - sorry about the ASCII art...)
