3.2.5 Alpha-Numeric Entry Keys

The Alpha-Numeric keys are used to enter data as needed during the

operation of the unit. There are three indicators associated with

keypad entry. These indicators appear in the title bar to the left of

the time. The three are as follows:

- alpha entry mode

- numeric entry mode

- multiple choice mode

Alpha Entry Mode

Most numeric keys have alphabetic characters printed on them.

These characters can be accessed when the alpha entry indicator

appears in the title bar. In the alpha entry mode, a cursor appears

below the active position. Repeated pressing of an alphanumeric key

sequences through the values printed on the key. Once the desired

character is selected, the cursor is moved to the next position using

the LEFT or RIGHT arrow keys. Special characters are available

using the UP and DOWN arrow keys.

Alpha entry must be terminated by pressing the ENTER key.
