3. Disconnect USB to stop the charge. Your instrument has a Li-ion battery, which has no memory effect.

You can charge your instrument while using it, for example in flight. You have to select “Charger Mode” when plugging the charge cable so the track recording doesn’t stop.

When starting the device, allow a dozen seconds for the battery level to stabilize.
