The RT27 necklace transmitter has been specially adapted to the requirements of people in need of care. The large push button makes it easy to operate.

Switching electrical devices on and off with a 1-button operation or activating paging systems are among the standard application areas of this transmitter.

An LED indicates if the battery needs to be changed. If the battery is running low, a separate radio signal is transmitted which can be analyzed by a corresponding Easywave receiver.
