Frequently Asked Questions: How does a self-powered doorbell work? The button has a built-in small generator or piezoelectric element that converts mechanical energy into electrical energy with each press. This electrical energy is used to send a signal to the receiver. Therefore, no batteries are needed, and it can work indefinitely as long as the button doesn't malfunction. What is the maximum effective range? In open, unobstructed areas, the maximum effective range is 400 meters. In actual use, the effective range may be shortened when encountering obstacles such as walls and doors, but this distance is sufficient for most homes and offices. Is the button truly waterproof? Yes, the button is IP68 certified, meaning it is completely dustproof and waterproof. It's submersible and resistant to rain, snow, and ice. Perfect for outdoor use! How do I set the ringtone and volume? There's a button on the receiver to browse 63 ringtones. Another button sets the volume to four levels (0dB, soft, medium, loud). You can also adjust or turn the RGB lighting off. What are the advantages of RGB lighting? Bright RGB lighting makes the doorbell clearly visible. This is ideal for people with hearing impairments or the elderly, or when you want to mute the sound (e.g., at night) and rely solely on the light to tell if someone is ringing the doorbell. Can I add multiple receivers? Yes, this doorbell set can usually be expanded by adding additional receivers (depending on the model). You can connect the button to multiple receivers so you can hear the doorbell in different rooms or on different floors. What happens if there's a power outage? The button operates independently of the mains power. However, the receiver must be plugged into a power outlet. If a power outage occurs, the receiver will not work unless you have a backup power source. The settings (ringtone/volume) will be retained.
