Wireless Chime BIGFOX 1 Transmitter 2 Receivers I purchased this to use like a nurse call system at home for elderly care in case of emergencies. I've had it for about two weeks, but I haven't used it much. It's convenient to have two receivers. It worked without any problems on the first and second floors. No wiring is required, and the receivers plug into the wall. Operation has been confirmed. The transmitter runs on batteries, and the batteries are dead. Therefore, I haven't been able to confirm its operation. The volume can be adjusted to 4 levels. The maximum volume is quite loud, so I think it would be fine for people with hearing loss. Shipping will be in a 60-size box, and the shipping cost is high, so I'm sorry I can't offer a lower price. 〈Reference〉 Transmitter: Uses a 12V23A alkaline battery High-sensitivity receiver: When it receives a radio wave from a distant push button, it notifies you with sound and light. A blue LED light flashes, making it easy to understand. The notification with light as well as sound is very helpful for the elderly with hearing loss. 52 melodies: 25-110dB volume, 52 kinds of music can be selected, satisfying a wide variety of environments and requirements. 300-meter wireless range: Adopts a high-sensitivity receiver, supporting a wireless range of 300 meters outdoors. Wireless, no wiring required: Simply plug the receiver into a power outlet, and you don't have to worry about running out of batteries. Installation is very easy. The transmitter is battery-powered, so it can be fixed to a door frame with screws or installed anywhere with 3M double-sided tape.
