Connector Engagement Check
Prior to configuration and checkout of the GTN, the connector engagement should be checked as
described below:
1.
Turn on the avionics master switch (if installed).
2.
Place the GTN in the rack and engage the cam mechanism.
3.
Turn the Allen screw of the locking cam (located on the lower left side of the unit) slowly
clockwise until the GTN just powers on. A T-handle can be used for this, but ensure that the
screw is not over-tightened.
4.
Count the number of complete revolutions the Allen screw can be turned until it cannot turn any
more. Take care not to over-tighten. Three turns is the minimum for proper installation. If fewer
than three turns are possible, the mounting rack should be moved aft (toward the pilot) such that
the aircraft panel does not obstruct the unit from properly engaging in the rack.

Configuration Mode Operations

configuration mode with the GTN turned off, press and hold the ‗Home‘ key and apply power to the
GTN. Release the ‗Home‘ key when the display activates and the Garmin logo appears fully lit on the
screen. The first page displayed is the Configuration Mode page, as shown in Figure 6-1. While in
configuration mode, pages can be selected by touching the desired key on the display.
