【Features】
This wireless type does not require wiring, making installation easy! It is also possible to add more transmitters and receivers according to your needs. (Up to 4 transmitters can be registered and used with one receiver.) You can add any number of receivers for one transmitter.
The radio wave reach distance is approximately 120 meters in a clear line of sight. It is ideal for calling or alerting in general households, stores, and offices.

With approximately 250,000 different ID codes (identification signals), there is no worry about signal interference.
The receiver indicates the timing of battery replacement with a lamp.
There are 20 types of alert sounds that can be set according to your preference.
Different sounds can be set for each transmitter, allowing you to identify which transmitter is sending the signal by sound.
When receiving, it notifies with a chime (sound) and flashing light (visual).
A lamp lights up corresponding to one of four transmission locations, so you can tell where the signal was sent from.
When it gets dark, the LED lights up, making it possible to identify the location; this is a rainproof push button.
*Please avoid installing in places where a large amount of water (such as guerrilla rainstorms or typhoon rain) directly contacts the device.*
