a (d) Execution of minutes setting ... When minutes setting is executed, seconds are cleared and the time is held as set. This is proved by the fact that when SW? is pushed/ released after execution of minutes setting the hours, minutes display appears but the colon remains lighted without flashing. By pushing/releasing SW7 or SW2 under this state, the time hold is released, timekeeping starts, and the normal hours, minutes display mode returns with the colon flashing. If in the minutes setting mode SW is pushed/released without execution of minutes setting, the setting mode returns to the normal hours, minutes display mode. 6. Sample Display of Each Mode 6-1.
