3.1 Menu Navigation
The CDU-250 Menu system is navigated by using the Arrow Keys and Enter Key (the key
marked by a circle) on the CDP-250. Use the arrow keys to navigate to the desired choice
and press the Enter Key to select it.
In any menu, pressing and holding the Enter key for 2 seconds will return the user to
the Home menu. The current activity will be aborted and any unsaved entry or edits
will be lost.
The CDU-250 has three types of menus – Selection Menu, Edit Menu and Information
Menu. The operation of these menus is explained below.
3.1.1 Selection Menu
The Selection Menu provides a list of options available to the user and the user can
navigate through the menu and select an item. The Up and Down keys are used to scroll up
and down in the menu. The Enter key selects an item and then opens the selected sub
menu item, or invokes a selected action.
The Left and Right navigation keys and the keypad panel have no functionality in this menu.
The Information Panel provides information appropriate to the menu. For example, in the
Home Menu, the Information Panel shows how many unread email messages are in the
inbox.

3.1.2 Edit Menu
The Edit Menu allows the user to enter text or numeric data using the Text keys on the
keypad. The user can switch between text and numeric modes by pressing and holding the
Up Arrow key for 2 seconds. If the alternate Mode is not displayed then it is not possible to
change between text/num modes for this edit menu. For example, on the Manual Dial Edit
Menu, text mode is not possible and, only numbers can be entered.
The Left and Right Arrow keys move the edit mode cursor one position to the left or right.
The Up and Down Arrow keys move the cursor to the previous or next line.
In any Edit Menu, a double press of the “0” key functions as a back space, and deletes the
previous character.
