2.3 Extend the alarm clock (nap mode)
When the AL1 is ringing, press the SNOOZE/DIMMER/CLOCK button to
temporarily silence the alarm for the set duration (9 minutes is the default).
The CIock stops the current ringing tone and enters the nap mode. Under
this mode, AL1 is flashing. To exit nap mode, press AL1 once while the
alarm is still on.
