When the answer-and-wait mode is activated, incoming calls have their caller ID information displayed and, in response to a key press or other input from the user, the call is answered and a wait message is transmitted to the caller, indicating that the call will be answered shortly. A shaft acceleration determination module determines a shaft acceleration based on at least one of the in-gear acceleration and the shift acceleration. The light-generating unit includes a magnet wheel disposed in the generator chamber and mounted coaxially and co-rotatably on the wheel-mounting portion of the axle, a coil device disposed in the generator chamber around the magnet wheel and mounted on the pedal body, and a lamp unit connected electrically to the coil device and mounted on the cage member. When the pressure is less than 150 psig, the molar percentage of tetrafluoroethylene in the non-ignitable gaseous composition is no more than 102\u22120.
