Note 1. When the startup mode is set to continue the operating mode last used be-
fore the power was turned off, that operating mode will be retained by the
built-in capacitor. If the power remains off for longer than the backup time
of the capacitor, the data may be lost. (For details on the holding time, refer
to the CPM1A or CPM1 Operation Manual.)
