Profile: Theta Corporation offers non verbal communication systems for dental and medical offices, which use colored lights to relay messages between the doctor and staff. We offer Theta Five-Lite System, Ten-Lite System and Multi-Channel Five-Lite System which communicate messages using colored lights in the same way office personal might communicate using voice. A message is sent by lighting one or more lights by pressing the pushbutton associated with those lights. These lights light in all areas where the intended receiver might be in.
