The 'CO2 DEVICE NOT READY' message on your ZOLL Medical Equipment indicates that the sensor or module needs to warm up, or it's not properly attached. Allow time for the sensor or module to warm up. Ensure the sensor or module is correctly attached to the unit. Also, make sure the sample cell is plugged into the sample cell receptacle on the module.
