Profile: Theta Corp. specializes in offering communication systems for dental & other medical offices which use colored lights to relay messages between the doctor and staff. We offer five-lite system, ten-lite system and multi-channel five-lite system which communicates 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 that the intended receiver might be in. When the receiver sees the message lights, the receiver answers yes by turning the light or lights out by pressing the reset button, or no by buzzing the buzzer or lighting an additional light. The no response is then acknowledged by the sender by turning out the lights.
