Configuration Mode Operations
Holding down the FUNC key and pressing the ON key provides access to the configuration pages. The
FUNC key sequences forward through the configuration pages. The START/STOP key reverses through
the pages, stopping at the first configuration page. The CRSR key highlights selectable fields on each
page. When a field is highlighted, the 0 – 9 keys enter numeric data and the 8 or 9 keys move through list
selections. Press the CRSR key to accept changes. When a field is highlighted, pressing the FUNC key
moves to the next configuration page without saving the changes.
Changes made through the configuration pages are stored in EEPROM memory. To exit the
configuration pages, turn the power off. Then turn on again (without holding the FUNC key) for normal
operation.

1. Hold down the FUNC key, then apply power to the aviation rack and the GTX 330 unit. Then (if
needed) press and release the ON key, to turn the unit on.
2. Release the FUNC key when the display activates, the unit is now in configuration mode.
Make configuration changes only as described in this section, changing other
configuration settings is not recommended and may significantly alter the unit's
operation. Garmin recommends recording all configuration settings (before making any
changes) for reference.
