1. Does this doorbell require Wi-Fi or an App?
No. This is a traditional wireless RF doorbell. It operates on a 433MHz frequency. It works instantly out of the box without needing Wi-Fi, apps, or Bluetooth.
2. How do I install the outside button?
You have two options:
Adhesive: Use the included double-sided tape to stick it to a clean, flat surface (glass, tile, wood).
Screws: Pop off the back cover and use the included screws/anchors to mount it to the wall for a permanent fix.
3. Can I have two buttons for different doors?
Yes! This system is expandable. You can pair multiple buttons (transmitters) to a single receiver. You can even set different ringtones for the front door and back door so you know where the visitor is.
4. What battery does the button use?
The transmitter button uses a standard CR2032 button cell battery (included). These are very common, cheap to replace, and typically last 6-12 months depending on usage.
5. Is the volume adjustable?
Yes, there are 4 volume levels.
Level 1: Mute (Light flash only) - Great for sleeping babies.
Level 4: Very Loud (85dB) - Great for hearing from another room or for the hearing impaired.
