current. You can review version information on AT-1 configuration webpage via WiFi.

Verify that the AT-1 is receiving traffic while on the ground. A pragmatic test using a
connected traffic display is recommended. All kinds of traffic targets, these are FLARM,
ADS-B and bearingless transponder targets should be shown depending on the traffic
situation.

Check for failure messages. Verify that no functions have failed and that no failure messages
are visible. If you are unable to open the AT-1 configuration webpage via WiFi and if there is
no system in your installation that is capable of displaying error messages, please monitor
the status LEDs instead.
