Using Control Center 67
Clearing GPS Data
The SC-1 has room for 35hours worth of GPS trackpoints. When the SC1's memory becomes full, the
oldest trackpoints on the device are automatically deleted to free up space for new ones. At any point
in time, the SC-1 will contain a record of your last several days of sailing.
Since old data is automatically deleted, you may never need to clear GPS data from the SC-1's memory.
If for any reason you do want to delete GPS data, select
Setup->Erase All Track Segments
.
Doing this will remove all track segments from the device. It is not possible to delete individual track
segments while keeping others. Performing the above procedure will not affect the user information
(your name, boat name, etc...) on the device.
