The PT-n screen appears. You can either:
• Change the value for the PT numerator.
• Access one of the other PT screens by pressing the Enter button: press Enter once to access the
Pt-d screen, twice to access the Pt-S screen.
a. To change the value for the PT numerator or denominator, from the Pt-n or Pt-d screen:
• Use the Down button to select the number value for a digit.
• Use the Right button to move to the next digit.
