Product description

• With a wireless range up to 1300 ft, the signal reaches through walls and across floors — so you can hear the chime clearly whether you're in the kitchen, upstairs, or at the far end of the house.
• No more missed visitors because you didn't hear the bell. No wiring, no tools needed.
• Plug the receiver into any indoor power outlet, then mount the button on your exterior wall with the included adhesive — the whole setup takes under 30 seconds.
• Use it at home, in the garden, at the office, or on a mailbox.
• Engineered for all-weather durability, this dust and waterproof radio doorbell endures temperatures from -30°C to 70°C. It withstands harsh conditions while boasting extremely low power consumption for a 1-3 year long-lasting battery life.
• The plug-in receiver offers 55 chime melodies and 5 volume levels from 0 to 110 dB, so you can pick a tone you actually like and set it loud enough to hear from anywhere.
• A built-in memory chip keeps your last settings after a power outage — no need to reprogram every time. Need coverage in more rooms?
• Add extra receivers or push buttons of the same model to expand your system — place one receiver upstairs and another in the basement, and every button will ring them all.
