2.3 CURSOR AND FIELDS
Alphanumeric Field Cursor on
Confirmation Field
Numeric Field Cursor on Cyclic Field
The area of the page which is underlined is called the cursor. The cursor
may be moved to locations on the page called fields which allow you to enter
data. You will encounter four types of fields.
· Numeric fields accept numbers. For example, you will enter a
waypoint's latitude in a numeric field.
· Alphanumeric fields accept numbers as well as letters. For example,
you will enter a waypoint's name in an alphanumeric field.
· Cyclic fields allow you to select from one of several available options.
For example, you may select between DTK (desired track), BRG
(bearing to waypoint), or CTS (course to steer) using a cyclic field.
Cyclic fields are indicated on the display by the “MORE” banner.
· Confirmation fields allow you to indicate your approval. For example,
you will be asked to confirm that you want to delete a waypoint.
Confirmation fields always end with a “?” character.

To turn the unit off, press and hold the PWR/BRT key for three
seconds until the display is blank.
