How to delete memory?

Each user has a storage space of 30 memories. When the memory is full, any new measurement is recorded by overwriting the oldest measurement in memory.

To delete all measurements stored in a user's memory space, hold down the M button for 3 seconds while viewing any measurement in memory.

 Before you delete the memory, make sure the measurements have been saved to another media so you can share them with your doctor. See How to keep your results?
