Operating Instructions
Once both the doorbell push button and chime units are powered and placed, the system is ready for use.
- Activating the Chime: When the doorbell push button is pressed, it sends a wireless signal to both the portable and plug-in chime units.
- Sound Alert: Upon receiving the signal, both chime units will sound the selected melody, alerting you to a visitor.
- Range: Ensure the doorbell button and chime units are within the effective wireless range. Obstacles like thick walls or metal structures can reduce the range.
Maintenance
Proper maintenance ensures the longevity and optimal performance of your door chime system.
- Cleaning: Wipe the doorbell button and chime units with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the surface.
- Battery Replacement (Doorbell Button): If the doorbell button stops working or its range decreases, replace the battery (e.g., 1 x 12V A23).
- Battery Replacement (Portable Chime): If the portable chime unit stops working or its sound becomes weak, replace the batteries (e.g., 3 x AA).
- Environmental Protection: While the doorbell button is designed for outdoor use, avoid prolonged exposure to extreme weather conditions.
