# III. Recharge the battery
1. To recharge your instrument, simply plug a cable into a USB port (computer, phone charger…). A light indicates the instrument is charging correctly. A full charge takes several hours. \
2. If the instrument is plugged in while operating, a menu appears and allows you to choose the action to perform:\
\- "**Charge**" : Continue to use it (even in flight), and charge the battery.\
\- "**Mass Storage**" : Connect the instrument to a computer as a "USB drive". \
\- "**Syride Link**" : Connect the instrument for communication with the Syride Link software.\
\
⚠️ **Important note:** The 2 modes "**Mass Storage**" and "**Syride Link**" stop the current flight recording if you activate them during a flight. Your instrument cannot be handled in these 2 modes: 
3. When operating and in 'Charge' mode, a swipe from top to bottom displays the information banner for a few seconds and allows you to check the battery charge status.\
4. Disconnect the instrument to stop its charging. The LI-ION battery has no memory effect.
