How to enter alphanumeric data
Alphanumeric input fields are activated for input by pointing with the mouse cursor and clicking the left mouse
button. This action also displays minimum and maximum values beside the input field. You select the input value by
spinning the scrollwheel then push the scrollwheel to accept the value. (Alphanumeric data may also be entered
directly from the keyboard-equipped control unit.)
To change a specific digit or alphabet, roll the trackball to put the cursor to the left of the digit or character that you
want to change then spin the scrollwheel to select appropriate alphanumeric character.
