The Chimeflash Telephone transmitter will alert you when your telephone is ringing via extra loud sounds, ultra‐bright flashing LED’s and coloured indicators on your Chimeflash Receiver. The Chimeflash Telephone Transmitter is designed to help people with hearing or visual impairments detect incoming landline calls. It works by monitoring a landline phone socket for an incoming signal and sending a wireless radio signal to a paired Chimeflash Receiver, which then alerts the user with loud sounds (up to 100dB) and bright flashing LED lights. You simply program this transmitter to the Chimeflash receiver via a couple of button presses and then plug the transmitter into the BT style phone socket using the double adapter provided - now whenever the phone rings, so will your Chimeflash!
