Maintenance
Water Resistance
The EIGIIS KE3BK Smart Watch is 3ATM water resistant, meaning it can withstand splashes, rain, and brief immersion in water, such as during hand washing or dishwashing.
Caution: Do not use the watch while diving, in a sauna, or during a hot shower. Exposure to hot water or high-pressure water jets may compromise the water resistance.
Cleaning
Regularly clean your watch and watch band to prevent skin irritation and maintain device hygiene.
- Wipe the watch screen and body with a soft, damp, lint-free cloth.
- For the watch band, use mild soap and water if necessary, then rinse thoroughly and dry completely before wearing.
- Avoid using harsh chemicals, abrasive cleaners, or solvents, as these can damage the watch's finish and seals.
Battery Care
To maximize battery lifespan:
- Avoid extreme temperatures.
- Charge the watch regularly, but avoid leaving it fully discharged for extended periods.
- Use only the provided charging cable.
