Remotly control per infrared and radio.
Environmental control is the remote control of devices.
With a transmitter, receivers are controlled by radio or infrared. Receivers can be the TV, a telephone with infrared receiver or an emergency call system.
A bed control provided with a receiver or a correspondingly equipped switch can be controlled, too.
Environmental control enables people with motor impairments to operate devices and systems in their environment adapted to their possibilities and thereby significantly improve the quality of life.
