摘要： An adjustment time reduction mode of reducing adjustment operation time is provided such that a user can set the adjustment time reduction mode in which a user arbitrarily reduces the adjustment operation time, depending on the user's situation. An apparatus performing adjustment operation at a predetermined timing, monitors a timing at which the adjustment operation is to be performed and visually notifies a user of the timing at which the adjustment operation is to be performed before execution of a job requested by the user. When the adjustment time reduction mode is set, the apparatus reduces a time for the adjustment operation during execution of the job requested by the user, and the apparatus is caused to operate in the adjustment time reduction mode until the job is completed.

摘要： In a system having plural CPUs, at least one of which is continuously operating and at least another of which is intermittently operating, autonomous counters monitor counter reset signal indicating normal operation of respective CPUs, each counter producing a CPU reset signal when it fails to receive a counter reset signal within a predetermined time period. To prevent erroneous indication of a malfunction and thus erroneous resetting of the CPUs when the intermittently operating CPU does not produce a counter reset signal within the predetermined time period while it is in its normal, non-operating state, a control circuit is provided to supply the autonomous counter monitoring the intermittently operating CPU with the counter reset signals produced by a continuously operating CPU while the intermittently operating CPU is in its non-operating state. The control circuit is advantageously used in portable mobile telephone sets and portable transmitter-receiver sets controlled by CPUs some of which are intermittently operated to save battery power.
