5. Maintenance
Water Resistance:
The SYNOKE Digital Sport Watch is rated for 50M (5ATM) water resistance. This means it is suitable for everyday use, swimming, and showering. However, to maintain its water resistance:
- DO NOT press any buttons while the watch is submerged in water.
- DO NOT expose the watch to hot water, such as in hot showers, saunas, or hot tubs, as this can compromise the seals.
- After exposure to saltwater, rinse the watch with fresh water and dry it thoroughly.

Cleaning:
Wipe the watch case and strap with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials that could damage the watch's finish or seals.
Battery Replacement:
The watch uses a CR2025 battery, designed for long-term use. When the display becomes dim or functions become erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure the water resistance seal is properly maintained.
6. Troubleshooting
- Display is blank or dim: Check the battery. If the battery is low, replace it.
- Time is incorrect: Re-enter the time setting mode and adjust the time and date as per the 'Setting Time and Date' section.
- Water inside the watch: If water appears inside the watch, stop using it immediately and take it to a professional for inspection. This may indicate a compromised water resistance seal, possibly due to improper use (e.g., pressing buttons underwater or exposure to hot water).
- Buttons are unresponsive: Ensure the watch is not in a locked mode (if applicable, though this model does not specify one). If issues persist, a battery reset (by removing and reinserting the battery) might resolve minor software glitches.
