Nice all-around watch/HRM that I purchased mainly for monitoring my heart rate during workouts and running. So, after several workouts, a "Memory Full" message is displayed whenever I scroll to the other features. It does not affect any of the operations, but it is annoying to me.
I believe workouts are saved every time you reset any of the timers, and the memory function works on the FIFO principle. There is no option in the menus to clear the workouts held in memory, only to "Lock", or preserve workouts you do not want erased when the memory rolls over. Hopefully, a "Clear memory?" option will be included in future releases.
