7. Care and Maintenance
7.1. Water Resistance Guidelines
Your UTHAI C08 watch is rated for 50-meter water resistance, making it suitable for daily activities such as:
- Bathing (cold/lukewarm water)
- Raining
- Swimming
Important: Do NOT operate buttons underwater unless specifically designed for diving. Avoid exposing the watch to hot water, such as in hot baths or saunas, as this can compromise the water seals.
7.2. General Care
- Clean the watch regularly with a soft, damp cloth.
- Avoid exposing the watch to extreme temperatures or direct sunlight for prolonged periods.
- Keep the watch away from strong magnetic fields.
8. Troubleshooting
- Display is blank: The battery may be depleted. Replace the battery.
- Time is incorrect: Re-enter the time setting mode and adjust the time as per Section 4.
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though not a feature of this model). If issues persist, a battery reset might be needed (consult support).
- Water inside the watch: Immediately stop using the watch and contact customer support. Do not attempt to open the watch yourself.
