OPERATING MODES

The ABRIS has four principal operating modes: MENU, NAV, ARC, and HSI. In each mode you can switch to various sub-modes using the FSK buttons. After the ABRIS has been turned on and gone through its self-test, the main MENU mode page is displayed. With each successive press on the right-most FSK button, the main modes are cycled as shown.

The current mode is indicated on the left side of the system bar. Navigational calculations and reception and transmission of information are performed continuously regardless of the current operating mode.
