Maintenance
1. Cleaning
To clean your watch, wipe it with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, which can damage the silicone band or display.
2. Battery Care
Recharge the watch when the battery indicator is low. Regular charging helps maintain battery health. Avoid completely draining the battery frequently. The watch saves all alarm settings even when powered off or during charging.
Troubleshooting
- Difficulty Setting Alarms/Time: The watch uses two buttons for navigation and setting. Refer to the detailed instructions in the included user manual for precise button sequences. Practice the steps without urgency.
- Watch is "Locked" or Unresponsive: If the watch becomes unresponsive, try connecting it to a charger. A low battery can sometimes cause unexpected behavior. If the issue persists, consult the full user manual for a reset procedure or contact customer support.
- Vibration is Weak or Non-existent:
- Ensure the watch is fully charged. Vibration strength can decrease with low battery.
- Check that the alarm or timer function is correctly activated.
- Ensure the watch is worn snugly on the wrist for optimal vibration sensation.
- Intermittent Functionality: If the watch stops working randomly, ensure it is fully charged. If the problem continues, it may indicate a hardware issue.
- Charging Port Difficulty: The USB charging strips are integrated into the band. When removing the module for charging, apply gentle, even pressure. Avoid twisting or forcing the module to prevent damage to the charging strips or the band.
