A mount for removably mounting a device to a reference surface is provided. The device includes a partly air-filled, upright tube placed on the inlet conduit of the piston pump, and a partly air-filled, upright tube placed on the outlet conduit of the piston pump. At least one of the divided conductive film parts functions as a radiation electrode. The control signal blocking part prevents the control signal from being applied to the current controlling unit when the detected voltage is lower than the reference voltage. The cable holder is disposed at a restricting point between the first end and the second end, whereby, when the second end moves to the first end, the cable holder contains and folds the flat cable. The method includes determining, by a Personal Digital Assistant module, whether a subscriber identification information request signal occurs; and directly accessing the SIM and reading the subscriber identification information stored in the SIM when the subscriber identification information request signal occurs.
