Softkey Function
The softkeys are located along the bottom of the displays. The softkeys shown depend on
the softkey level or page being displayed. The bezel keys below the softkeys can be used
to select the appropriate softkey. When a softkey is selected, its color changes to black
text on gray background and remains this way until it is turned off, at which time it reverts
to white text on black background.

System Power Up
The G1000H system is integrated with the aircraft electrical system and receives power
directly from electrical busses. The G1000H PFD, MFD and supporting sub-systems
include both power-on and continuous built-in test features that exercise the processor,
RAM, ROM, external inputs and outputs to provide safe operation.
During system initialization, test annunciations are displayed. All system annunciations
should disappear typically within one minute of power-up at normal temperature, but may
take as long as 10 minutes at cold temperatures. Upon power-up, key annunciator lights
also become momentarily illuminated on the audio panels, the control units and the display
bezels.
