Tips for Maintaining Your Rechargeable Battery
Full Initial Charge
- Charge your battery fully for 8 hours before its first use to ensure proper function.
Maintaining Battery Life
- Discharge the battery periodically to maintain its longevity.

Resolving Weak Reception
If the reception between the Parent Unit and Nursery Unit is weak, try these solutions:
- Move the units closer together to improve the signal.
- Adjust the position of one or both units for better reception.
- Place units on a flat surface away from the baby to ensure proper functionality.
