2. Your instrument will display “Charging…” and the percentage of charge. To complete, a charge requires 2 hours.

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

4. When your instrument will start, the battery icon needs 10 seconds to be stable.
