remains set after its time has passed, and will sound again every successive day until it is erased.
Note 2. Set alarms are automatically organized in the order of next to go off, according to the time of day. In other
words, when you check your set alarms, ALARM 01 will be the next to signal, then ALARM 02…etc.
Note 3. SNOOZE button - When an alarm signals, press the light button to turn off the alarm and engage the
snooze feature; the alarm turns back on automatically after 5 minutes. You can only do this once with each alarm.
