PURPOSE:To prevent malfunction by generating an autio warning sound when switch is not operated within a set time in the state in which the operation of time correction switch is made effective. CONSTITUTION:When a control switch 38 is turned on to set the state for correcting time, a voice generation circuit 39 emits the voice indicating the state for correcting time. A countr 64 starts counting, and when a set second time elapses with no executed operations, a warning sound is generated from the circuit 39. When the set second time elapses after the correction is made with operation switches 20, 22, 24, the warning sound is similarly generated by the output of a counter 80. |
