Purging Waypoints, Routes and Trails
Deleted Waypoints, Routes and Trails are stored in the HDS Gen3
Polaris memory until the data is purged. This is necessary to allow
user data to be synchronized across multiple units on an Ethernet
network. If you have numerous deleted, unpurged Waypoints,
purging may improve the performance of your system.
Note:
Ú When user data is purged from the memory, it
cannot be recovered.
