Function and Principle：The door magnet is installed on the door of the refrigerator, and whenever someone opens the freezer, it will emit a "ding ding ding" sound to remind the owner.

(Also adjustable to "Hello, welcome!" or other prompt sounds, with a total of 41 ring tones.) The door magnet and the buzzer are separate.

It is possible to open the refrigerator outside and hear the sound inside.

About door magnetThe door magnet is a sensor device on the door, and multiple door magnets can be used on multiple refrigerators, connected to the same buzzer. If any refrigerator door is opened, the buzzer will ring. The door magnet uses a 7th battery, and it needs to be replaced every ten months or so.

"关于响铃"可以翻译为 "About the Bell" 或者 "On the Bell"。Buzzer is a accessory that emits a ringing sound. There is no need for wiring between the buzzer and the door magnet, nor does it require WiFi. The wireless signal range can reach up to 20 meters. The buzzer can be used with 3 AA batteries. If you do not want to install batteries, you can also use an Android charging cable to keep it plugged in. There is an Android interface on the side of the buzzer.

About Remote ControlThe function of the remote control is to control the switch, adjust the mode, and adjust the volume. The remote control is not a standard equipment, and if you do not buy the remote control, you can control it by pressing the buttons on the side of the bell.

Door magnet size: 7.5*2.7*1.7cm; Inductive magnetic strip size: 4.1*1.2*1.5cm
