7. Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Watch does not power on. | Battery might be depleted. Charge the watch for at least 30 minutes. If still unresponsive, perform a hard reset (refer to specific device instructions or contact support). |
| Cannot pair with smartphone. | Ensure Bluetooth is enabled on both devices. Make sure the watch is in pairing mode. Restart both the watch and smartphone. Check the companion app for specific pairing steps. |
| Short battery life. | High screen brightness, frequent notifications, continuous heart rate monitoring, or GPS usage can drain the battery faster. Adjust settings to optimize battery life. Ensure the watch is fully charged. |
| Screen is scratched or damaged. | While the watch features a scratch-resistant sapphire crystal bezel, extreme impacts can still cause damage. This is typically not covered under standard warranty. |
| Watch is unresponsive or frozen. | Try restarting the watch by pressing and holding the side button. If that doesn't work, perform a forced restart (consult the companion app or manufacturer's website for specific instructions). |
