The visual display incrementally lights groups of pixels on the electroluminescent display.

The unit shows the GPS signal strength screen in the GPS Sensor function. Make it a habit to check this screen to make sure that the unit is properly tracking visible satellites before you fly. The Apollo GX requires signals from at least four satellites to calculate a 3D position fix (Lat/Lon and GPS altitude). More details are available in the GPS Sensor part of the System section of this manual, see page 17.
