Six buttons lined up across the bottom of the LCD provide access to the various functions of the instrument. Each button acts as a “Softkey” control or function as defined by the menu system label presented immediately above each button. The menus are normally hidden to maximize the use of the screen when not in use. Pressing any of the buttons activates the menu system which then assists the pilot to the desired function.

The menu system is arranged in a hierarchy with those most frequently used near the front end. Softkey functions include:

• Setting the Barometer
• Setting Bugs for:
  • Airspeed
  • Altitude
  • Heading
• Displaying Checklists or Aviation Data
• Starting the Timer or Setting the Clock
• Dimming the Screen for Night Flight
• Powering the Instrument
• Setting the Correct Pitch on the Attitude Display
• G-Meter Recorder Reset
• Setup Parameters including items like:
  • Units of Measurement
  • Airspeed Bar Colors
  • Screen Declutter
  • Calibration of AOA and Magnetic Heading
