### # Troubleshooting

If you are having trouble connecting to your Instrument, please go through this checklist first:

• Make sure your Instrument is fully charged (at least 6h, or over night).
• Make sure you have turned on the Instrument by pressing and holding the power button for at least 5 seconds. The Instrument will automatically shut off after 3 hours of inactivity by default.
• If you were using the Instrument with another mobile device, you will need to press and hold the power button for 5 seconds to disconnect it from the current device and make it available to the new one.
• If you are using Windows 8 or lower, make sure you have the serial driver (opens new window) installed.
