Check to see that your clicker is on the proper channel; the
  channel indicator is in the upper left-hand corner of your
  NXT Response Card screen.  The Turning Point receiver currently
  in PSF-173 is on channel 58.  This classroom-receiver channel
  number will be visible on the classroom computer screen once
  the classroom Turning Point software has been started for that
  day. 

  To change the channel on your NXT clicker, please do the following:

    * Press the Channel Button (second highest button on the left
      hand side of the clicker)

    * Use the number pad to enter the new channel number

    * Press the Enter Button (an oval button with a white dot at
      its center).  THIS STEP IS VERY IMPORTANT.

  In PHY 121 and 131, we use only single response mulitple choice
  questions.  When responding to questions in class, press your
  selected response button firmly.  Your response will be confirmed
  in the following way:

    * You will see your answer on the screen, i.e. 1/A, and you
      will see a smiley face under the answer.

  As long as the question is still open for polling, you can always
  change your answer by simply entering a different answer.

  Here is the NXT ResponseCard Guide as provided by Turning Point.

  As described in the Turning Point policies, ONCE during 
  the session I will change your TP score if you tell 
  me you were present but your TP score was not 
  recorded properly, either because your batteries
  were dead or even if you forgot your clicker.  Send 
  me an email indicating the necessary change.  I must
  receive this email within TWO DAYS of the relevant
  lecture.

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

  If you have any questions about using your clicker
  that are not answered here, visit the Turning Point
  ASU Student Support webpage or make an appointment
  with the ASU Clicker Support Team.
