A mobile terminal is disclosed having a controller responsive to a status information display command inputted for detecting status information stored in a storage unit and displaying all of the status information at one time via a display unit. At a center of the light-receiving area, the micro-lenses are placed in positions directly above corresponding photodiodes, and placed in positions which are progressively offset from positions directly above the corresponding photodiodes, towards a center of the light receiving area, as micro-lenses are located farther from the center of the light-receiving area. The patient electrodes also allow obtaining a signal which is a measure of the patient’s transthoracic impedance and the microprocessor is responsive to Z to detect conditions likely to cause the diagnostic algorithm to generate a false detection of a shockable rhythm. A second rail, perpendicular to the first rail, is movably connected to the first rail such that the first seat is selectively movable along both the first rail and the second rail.
