The present invention is directed to converting a non-hospital-ready electronic device into a hospital-ready electronic device. The invention requires (1) a non-hospital-ready electronic device having an infrared remote control system that receives an infrared signal through a window; (2) a pillow speaker that generates in response to a user's input a first data signal to alter the operation of the non-hospital-ready electronic device; and (3) a data to infrared isolated interface device. The interface device receives the first data signal, and isolates the non-hospital-ready electronic device from the pillow speaker through a phototdiode and a photosensitive transistor. The photosensitive transistor generates a second data signal that corresponds to the first data signal and is generated in response to the first data signal contacting the photodiode. The second data signal is directed to an infrared emitter that is positioned near the window and generates an infrared signal that corresponds to the second data signal. The infrared signal is transmitted into the window which allows the non-hospital-ready electronic device to be controlled by the user through the pillow speaker.
