The GNS-430/-530 NAV/COM/GPS and the GTX-327/-330 Transponder each have lighting configuration
settings which must be adjusted after installation. Whenever a unit is replaced, use the following
procedures to configure the lighting in the new unit.
A. GNS-430/-530
With power applied to the avionics rack and the GNS-430/-530 turned off, press and hold the ENT
key and turn the unit ON. Release the ENT key when the display activates. After the data base
pages, press the ENT key twice (to step through the Data Base Information and Indicator Self Test
Pages). The next page displayed is the MAIN ARINC 429 CONFIG page.
While in Configuration Mode, pages can be selected by ensuring the cursor is off and rotating the
small (inner) right knob. Do this now and select the MAIN LIGHTING PAGE.
To change data on the displayed Main Lighting Page, press the small (inner) right knob (CRSR) to
turn on the cursor. Turn the large (outside) right knob to step through the data fields. Turn the small
(inner) right knob to change the data in the field that the cursor is on. Press the ENT key to accept
the data that is displayed in the selected field.
Configure a newly installed unit as shown in Chart 2.
NOTE: Initial configuration may be done using aircraft battery or external power. Final performance
