You can set ﬁve independent daily alarms. When a daily alarm is turned on, an alarm tone will sound for about 20 seconds each day when the time in the Timekeeping Mode reaches the preset alarm time. This is true even if the watch is not in the Timekeeping Mode. One of the alarms is a snooze alarm, while the other four are one-time alarms. The snooze alarm operation repeats every ﬁve minutes.

You can also turn on an Hourly Time Signal, which will cause the watch to beep twice every hour on the hour.

ξThe snooze alarm screen is indicated by SNZ, while the other alarm screens are numbered AL1 through AL4. The Hourly Time Signal screen is indicated by SIG.

ξWhen you enter the Alarm Mode, the data you were viewing when you last exited the mode appears ﬁ rst.
