4.2.3  Activation with GPS I/O (P/N 2799.4 Only) 
The AeroFix™ 406 GPS I/O is also equipped with an Onboard GPS receiver. Once activated the 
AeroFix™ 406 GPS Onboard GPS engine will start up and search to find your LAT/LON and 
incorporate it into your 406 MHz signal. In the case when external and internal GPS are present, the 
internal GPS data will have priority at activation. 
When the AeroFix™ 406 
GPS I/O is turned ON, the GPS Onboard receiver is also immediately 
turned ON and will immediately begin acquiring data. As soon as the GPS receiver acquires good 
positioning data the red LED will stop blinking and the green LED will begin flashing once every 2 
seconds. Once good global positioning data has been obtained, the GPS receiver waits for 20 
minutes before looking for new positioning data again. If for any reason a time period of 4 hours 
passes without the GPS receiver being able to update the last good set of GPS coordinates, the 
message transmitted by the AeroFix™ 406 
GPS I/O will revert to default data. At this point the 
green LED will stop blinking and the red LED will flash once every 2 seconds. If at any time after 
this, good GPS data is obtained, this data will be transmitted, the red LED will stop blinking and the 
green LED will begin flashing again.
