Selected by pressing the left-most FSK button when in the MENU operating mode, the OPTION sub-mode page affects all the modes of ABRIS operation and is stored in non-volatile memory. Options can have values selected from a list or from a defined digital range. ATTENTION! It is advised that you do not change option values unless you are certain of the consequences on ABRIS functionality.
Modified OPTION values are saved at the time of exiting from the sub-mode – a press of the OPTION button. Note that when entering data for coordinates, date, time, etc., that after selecting the line item and pressing the CHANGE FSK button that the bottom of the display will change to allow you to select the field you wish to edit, and by rotating the cursor manipulator control you select the value.

Procedure to Change ABRIS Settings
In the OPTION sub-mode, there are five sub-modes that can be displayed by pressing the SETUP FSK button. When this button is pressed, a pop-up menu is displayed with the following options:
You may then select one of the options by pressing the up and down arrow FSK buttons or by rotating the cursor manipulator. Once a line item has been selected (boxed in the menu), press the SETPUP FSK button again or press the cursor manipulator to display the page. To change between the pre-determined option/values, use the CHANGE FSK button; to switch from one line-option to another in the menu, use FSK buttons with the or ∆ symbols or the cursor manipulator knob. The selected function is highlighted with a box.
MENU/OPTION/MAIN Sub-mode
The default page of the MENU/OPTION sub-mode is the MAIN sub-mode page. Using the sub-mode pop-up window, you may select MAIN to return to this page. The table below lists MAIN page options, possible values (values or formats) of options, and their effect on ABRIS functionality.
