B. GTX-327/-330
With power applied to the avionics rack and the GTX-327/-330 turned off, press and hold the FUNC
key and turn the unit ON. This provides access to the configuration pages. The FUNC key
sequences forward through the configuration pages. The START/STOP key sequences the
configuration pages backward. The CRSR key will highlight selectable fields on each page. When a
field is highlighted, the numeric data entry will be performed with the 0-9 keys, and list selections
will be performed with the 8 or 9 keys. Press the CRSR key to accept changes. Pressing the FUNC
key moves on to the next configuration page without saving the changes. To exit the configuration
pages, turn the power off and then on again (without holding the FUNC key).
Configure a newly installed unit as shown in Chart 2.
NOTE: For the GTX-330 only:
address is recognized, the unit will prompt the user to enter a valid aircraft address. See
latest revision of Garmin GTX-330 Installation Manual, P/N 190-00207-02.
