APPENDIX C - USER INTERFACE: DIGITAL DISPLAY

activation. The messages on the digital display typically appear as one or two words at a
time, until the entire message has been displayed.

The system reminds you that for optimum GPS performance, i.e., greatest likelihood of
acquiring coordinates, position the beacon so that it has a clear view of the sky.
The system reminds you that for optimum transmission of the emergency message,
allow the beacon to float and do not hold the antenna (aerial).
The system reports that the 406 MHz emergency message has been sent. If this
message accompanied by a green LED flash, the GPS coordinates have been sent as
well. If accompanied by a red LED flash, the GPS coordinates have not been sent.
NOTE: If GPS coordinates were not sent, the system will continue to attempt to
acquire the data and add it to the 406 MHz distress signal when available. Updated
GPS coordinates are sent every twenty minutes.
This message appears only if GPS data was acquired
