How do I clear or delete my health data from the device’s memory?

You can clear the data on the PC-60FW by removing the battery for 30 seconds and replacing it. You can delete a record from the app by logging into the app > select the Records tab > select Blood oxygen measurement record > select the pencil icon in the upper right corner of the app > select the circle next to the record you want to delete > then select the garbage can icon in the upper left corner of the app.
