Abstract: A battery-powered medical apparatus including a first memory configured to store a first program, a second memory configured to store a second program, which is different than the first program, and a processor. The processor executes activation of the battery-powered medical apparatus by executing the first program stored in the first memory in response to receiving an activation instruction. In response to the activation failing to complete within a first predetermined period of time, the processor switches from the first program to the second program, and executes the activation of the battery-powered medical apparatus by executing the second program stored in the second memory. The processor then stops power supply from a battery in response to the activation executed by the second program failing to complete within a second predetermined period of time.

Abstract: A processor first executes activation through a first program stored in a main memory when there is an activation instruction, a switching unit switches a program from the first program to a second program in sub memory when activation through the first program is impossible within a first period of time, and the processor halts power supply from the battery when activation through the second program is impossible within a second period of time.

Abstract: A voice recording/reproducing apparatus in accordance with the present invention includes a recording medium, a recording unit, a playback unit, and a reproduction manipulating unit. The recording unit records by voice the items of a schedule for each day on the recording medium. The playback unit reproduces by voice the items of a schedule for each day which are recorded on the recording medium. The playback manipulating unit is used to designate a day of a year for which a schedule must be played back, and to instruct the playback unit to play back the items of the schedule for the designated day. The recording unit can record a plurality of schedule items as the items of a schedule for each day. All the schedule items for the designated day are played back responsive to one manipulation performed on the playback manipulating unit.
