Wireless Chime Transmitter and Receiver Set (Call/Care) Sanwa Supply <Transmitter Battery Free>

Wireless Chime (AC Powered Receiver, Self-Generating Transmitter Set + Additional Transmitter)
- The basic set with one transmitter can be used immediately by plugging the receiver into an outlet.
- By setting up the spare transmitter (purchased additionally but unused) for expansion, you can make it produce the same tone as the set's transmitter or set it to a different tone for distinct alerts.
- The transmitter generates its own power by pressing the button, so no battery replacement is needed, making it maintenance-free.
- Rounded design with no sharp edges, comfortable to hold.
Used for caregiving for my mother between the first floor of a wooden house and the second floor of an adjacent detached building.
Depending on the conditions, the simple structure without a communication function means fewer breakdowns, and the radio waves tend to reach quite far.
[Please note that there is absolutely no communication function.]
Please refrain from purchasing if you are sensitive.
No claims, no returns.

This product can be used up to approximately 50m in a clear line of sight without obstacles, but in the following cases, radio waves may not reach well and it may not be usable:
1. When separated by multiple walls or doors between devices.
2. When used in buildings constructed with reinforced concrete or steel frames.
3. When used between different floors or different buildings.
4. Obstacles (concrete walls, metal exterior walls, walls with insulation material, metal furniture or doors, metal doors or storm shutters).
Can be used as a doorbell at the entrance (transmitter can be mounted on the wall, but not waterproof/drip-proof), as well as a call bell for shops, offices, and for nursing care.
Simply plug the receiver directly into an outlet for use, eliminating the need for construction such as drilling holes in walls.
The receiver has 52 types of melodies and 5 volume levels that can be adjusted by pressing the volume button.
With a maximum volume of 100db, it is ideal for installation in places where sound is difficult to hear.
