A protective coating which is removable with a removing agent comprising a strong base, which protective coating comprises a pigment, a weak base and a binder, the binder being a polymer having a weight-average molecular weight of 10,000-100,000 and an acid value of 40-250. The comparingjudging unit 125 judges, when the predictive amount in the receiver buffer is below the threshold, that encoding the image data is to be skipped, and makes the DCT unit 113 cancel the encoding process. The method comprises venting a center chamber of a flexible membrane configured for mounting the substrate, moving the substrate such that a backside of the substrate is in full contact with the flexible membrane, and vacuuming the center chamber to vacuum chuck the backside of the substrate to the flexible membrane. The tubular member has a first end fixed to the wall of the elongate shaft, and a second end disposed within the shaft lumen. The invention further relates to an electronic device provided with such a battery.
