4. Maintenance
Water Resistance:
The Ayybboo Kids Digital Watch MR-2207B is rated for 3 ATM (30 meters) water resistance. This means it is suitable for:
- Daily splashes
- Rain exposure
- Hand washing
Important:
- Do NOT press any buttons while the watch is submerged in water.
- The watch is NOT suitable for showering, bathing, swimming, or diving.
- Avoid exposing the watch to hot water or steam, as this can compromise the water seals.

Cleaning:
To clean your watch, wipe it gently with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, which can damage the watch's finish or seals.
Battery Replacement:
The watch uses a button cell battery. When the display becomes dim or functions are erratic, it may be time to replace the battery. Battery replacement should ideally be performed by a qualified watch technician to ensure water resistance is maintained.
5. Troubleshooting
- Watch not displaying time / Display is dim: The battery may be low or depleted. Replace the battery.
- Buttons not responding: Ensure the watch is not in a locked mode (if applicable, though this model does not have a specific lock). If issues persist, try removing and reinserting the battery (professional assistance recommended).
- Time is incorrect: Follow the 'Setting Time and Date' instructions in Section 2 to reset the time.
- Water inside the watch: Immediately stop using the watch and seek professional repair. Water damage is typically not covered under warranty.
