Robust and Waterproof Push Button
The replaceable 230 mAh CR2032 lithium battery has an ultra-long lifespan of up to 3 years, saving you the annoyance of frequent purchases and replacements.
The impressive IP55 dustproof and waterproof rating and the approved working temperature range of -4 °F to 140 °F make the sender button tough enough to withstand almost any outdoor conditions.

Simple Installation
The push button is easily attached to a wall or doorframe with the provided screws or adhesive patch.
The receiver bell only needs to be connected to a power socket and does not need to be wired to the push button.

Pleasant Melodies & Various Volume Levels
The huge selection of 52 tunes guarantees you will be able to find something you like and suit your seasonal mood.
The built-in 40 mm stereo speaker delivers clear and well-balanced sound up to 115 dB, meaning it is loud enough to be heard in other rooms and by those with impaired hearing.
The receiver bell can be muted whenever quiet is needed, using the LED indicator to still show when you have a visitor.

Long Operating Distance
The doorbell supports an extensive 1,312 ft working range (depending on the operating environment), making it viable for most long-range setups in houses and gardens.

NOTE:Metal will interfere with the signal and shorten the transmission range. Please place the transmitter in areas away from metal.

Convenient Memory Function
The built-in memory function is a convenient feature that remembers your set melody and volume level even after a power outage, so you do not have to deal with the hassle of resetting the device every time the power goes out.
