When using your transmitter, first be sure that it 
is turned on. To submit your answer, point it at one 
of the PRS receivers scattered about the room. An 
image of a receiver is shown below. 
                      

  You may answer any question twice within the given 
time limit (once is all that is necessary). You may 
change your answer the second time. If you submit two 
answers, only the second answer will be graded. The H 
(high) and L (low) buttons can be used to indicate 
your confidence in your answer; this information will 
not be used in any way this year.

  Use the receiver nearest to you.  Many people like
to aim at the receiver directly above the computer
screen; that receiver consequently has high traffic
and is generally not the best receiver at which to
aim.

  Repeatedly pressing an answer button on your
clicker is NOT effective.  You MUST wait for the
green light on your clicker to stop flashing
before resubmitting an answer.

  IMPORTANT: IT IS YOUR RESPONSIBILITY TO MAKE SURE 
THAT YOUR TRANSMITTER IS IN WORKING ORDER AND THAT 
YOUR SUBMITTED ANSWERS ARE RECEIVED. Watch for your 
PRS ID number to appear on the computer screen at the 
front of the classroom; this will indicate that your 
submission has been received. The computer screen 
will look something like this, except it will have 
100 boxes instead of 20.
     

There is a color associated with your number.  Learn
your color; then you only have to look for boxes of
that color.  On the screen above, the box for the 
clicker with number 000001289 is a dark shade of 
green; responses from clicker 000001289 will always 
be in a box of this color.  If you succeed in 
answering three times your box color will change to 
red.  For example, on the screen above, the clicker 
000999999 has answered three times.  If you are 
satisfied with your answer, please don't enter extra 
responses; this only makes things more difficult for 
others trying to enter their responses.  IF YOU HAVE 
SEEN YOUR NUMBER, THEN YOUR ANSWER HAS BEEN RECORDED.

  As described in the PRS policies, ONCE during 
the session I will change your PRS score if you tell 
me you were present but your PRS score was not 
recorded.  Send me an email indicating the necessary 
change.  

   IT IS YOUR RESPONSIBILITY TO MAKE SURE THAT YOUR 
TRANSMITTER IS IN WORKING ORDER AND THAT YOUR 
SUBMITTED ANSWERS ARE RECEIVED.
