Power Up
1. Push the PWR/VOL knob in to turn on power.
2. When the position display appears, you can press CHG to manually enter
your present position or just wait a few seconds for the GNS 480 to
establish your position. The full power up sequence takes 2-3 minutes.
3. The GNS 480 performs a number of tests at startup to ensure proper
operation. You may press SKIP to bypass the startup tests, however,
completing these tests is required for IFR flight. Observe the tests and
needle swings for proper operation.
Database Check
The GNS 480 verifies the integrity and
expiration date of the database. Up to
two database cycles are supported. The
GNS 480 will load the appropriate current database cycle and also let you know
if a database is not current (dates invalid
or corrupt) with a message in amber.
