Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Device does not power on. | Low battery; device frozen. | Charge the device for at least 30 minutes. If still unresponsive, try a hard reset (refer to manual for specific reset instructions, if any, or hold power button for 10-15 seconds). |
