what your Calibrate button is telling you
Located somewhere on your socket, you should have access to the Coapt Complete Calibrate button. This oval unit has one pressable button, a Coapt logo, a multi-colored LED light, and it can make a series of tones for you to hear. This reference guide is designed to help you decipher what these lights and sounds mean while working with your Coapt Gen2® System.
