To turn off the audio:

  1. Launch the program.
  2. Select one of the courses from the main selection area.
  3. Select one of the sub-topics for the course.
  4. On the sub-topic’s window, click on the speaker icon that appears near the Next button in the top left-hand corner.

Note: This will only disable the narration for your current session in the program. If you open other courses or sub-topics at this time, the narration will stay off. However, if you close the program all the way and then re-launch it, you will need to disable the narration once again.
