An electrophotographic photosensitive member is provided in which both a potential variation over a long time period and a potential variation within a short time period are suppressed. The processor is configured to receive the selector from the memory, select an operational parameter of the circuit protection device based on the selector, receive a voltage value representative of a selected voltage provided by the adjustment device, and set the selected operational parameter to a parameter value based on the voltage value received. In such a configuration, the data transfer for application processing is executed mainly in the upper enclosure. The charge storage element is located over the channel region and the control gate element is arranged on top of the charge storage element. The module includes a second communication radio utilizing a second frequency band so that, when the removable module is inserted into the slot, the access point is capable of communicating with a second wireless device via at least one of the first and second frequency bands. During the melting stage carbon monoxide is afterburned by gas-oxygen burners forming carbon dioxide in the exit gasses supplied to the gas exhaust system through the coaxial chamber.
