The reader needs to be recharged if it runs out of power. The stored glucose readings on the reader are not lost. The reader should fully charge in approximately 3 hours if the battery is completely discharged.
With normal use, the reader can be used for approximately 7 days before it needs to be recharged. A low battery warning will appear on the reader when it needs to be recharged. There is a battery icon on the reader which will indicate battery life.
Yes, you can get glucose readings through clothing by scanning the reader over the sensor.*
* The reader can capture data from the sensor when it is within 1cm to 4cm of the sensor.
The oldest glucose readings will be lost if the reader is not scanned at least once during an 8 hour period. For example, if you scan the reader over the sensor at 1:00pm and again at 10:00pm, then you will lose glucose data from 1:00-2:00pm.
The reader is smart enough to figure out what data is new with each scan and not double-count any data.
