It's environmentally friendly and sustainable with zero running costs. Installation is also easy, with the transmitter attaching in 3 seconds using double-sided tape, requiring no construction, making it safe for those who don't want to damage their walls or for rental properties. The receiver can be used immediately by plugging it into an outlet. It can also be fixed with screws if necessary. Its compact size is ideal for the narrow entrances of Japanese homes and for adding to multiple doors. (※Communication may become unstable if used near metal doors. Be sure to choose a location away from metal structures.) 【Weatherproof Design & Memory Function】 It clears the IP44 waterproof and dustproof standards, and is suitable for the humidity of the rainy season and snowfall. It operates in temperatures from -20°C to 60°C, so it can be used throughout Japan, from Hokkaido to Okinawa. It has a backup function that remembers settings even during a power outage, providing peace of mind during disasters. It works even in sudden rain or dusty environments when installed outside the entrance. 【Wide-Range Communication & Free Expansion】 The wireless chime has a communication range of up to 300m in an area without obstacles. The sound reaches even in complex Japanese houses, such as detached houses with gardens, apartment hallways, and entrances. (※Differences in the installation environment may affect the communication distance.) Multiple sub-receivers can be added, and can be installed in separate rooms or on the second floor. When a visitor arrives, you can receive chime notifications anywhere in the house, making it useful for monitoring the elderly. 【Over 60 Ringtone Types & 7-Level Volume Adjustment】 It has over 60 built-in chime ringtones that are familiar to Japanese life. You can change the chime sound according to the season or the visitor. The volume of the wireless chime can be adjusted in 7 levels from 0-115dB, and can be heard on the second floor. It also notifies with light in silent mode. It can be used without stress in households with children or pets, and in areas with noise regulations at night. ーーーーー
