4. Activating Your Beacon
Activation with GPS
When your unit is activated, the GPS receiver will turn on, search to find your LAT/LON and
incorporate it into your 406 MHz signal. As soon as the GPS receiver acquires valid
positioning data, the red flashing light will be replaced by a green flashing light once every 3
seconds.
T
he same GPS data will be sent with each 406 MHz signal for the next 30 minutes. At that
time the internal GPS will start up again, search to find your LAT/LON and incorporate it into
your next 406 MHz signal. If for any reason the internal GPS cannot update your LAT/LON,
your last position will be used for the next four hours. At that time the green LED will stop
blinking and the red LED will flash once every 3 seconds until new GPS data is obtained.
