The CLR Key is used to erase information, remove map detail, or to cancel an entry. Press and hold the CLR key to immediately display the Default NAV Page.
The ENT Key is used to approve an operation or complete data entry. It is also used to confirm information, such as during power on.
The large right knob is used to select between the various page groups: NAV, WPT, AUX, or NRST. With the on-screen cursor enabled, the large right knob allows the pilot to move the cursor about the page. The large right knob is also used to move the target pointer right (turn clockwise) or left (counterclockwise) when the map panning function is active.
The small right knob is used to select between the various pages within one of the groups listed above. Press this knob momentarily to display the on-screen cursor. The cursor allows the pilot to enter data and/or make a selection from a list of options. When entering data, the small knob is used to select the desired letter or number and the large knob is used to move to the next character space. The small right knob is also used to move the target pointer up (turn clockwise) or down (counterclockwise) when the map panning function is active.

The NRST Key displays the Nearest Airports Page. Then, turning the small right knob steps through the NRST pages.
The OBS Key is used to select manual or automatic sequencing of waypoints. Pressing the OBS Key selects OBS mode, which retains the current ‘active to’ waypoint as the navigation reference even after passing the waypoint (i.e., prevents sequencing to the next waypoint). Pressing the OBS Key again returns the unit to normal operation, with automatic sequencing of waypoints. When OBS mode is selected, the pilot may set the desired course to/from a waypoint using the ‘Select OBS Course’ pop-up window, or an external OBS selector on the HSI or CDI.
The MSG Key is used to view system messages and to alert the pilot to important warnings and requirements.
The FPL Key allows the pilot to create, edit, activate, and invert flight plans, as well as access approaches, departures, and arrivals. A closest point to flight plan feature is also available from the FPL Key.
The PROC Key allows the pilot to select and remove approaches, departures, and arrivals from the flight plan. When using a flight plan, available procedures for the departure and/or arrival airport are offered automatically. Otherwise, the pilot may select the desired airport, then the desired procedure.

3)Once the self-test concludes, the Database Versions Page appears which shows the current database information on the NavData® Card and Terrain Data cards. Press the ENT Key to acknowledge the Database Page and proceed to the Instrument Panel Self-test Page.
4)The Instrument Panel Self-test Page allows the pilot to verify that the GPS 400 is communicating properly with in-panel instruments. Compare on-screen indications with the information depicted on connected instruments, such as the CDI, HSI, RMI, and/or external annunciators.
5)After verifying proper operation, press the ENT Key to display the Satellite Status Page.
