ALARM
The unit has an audible alarm that sounds for one minute when the timer counts down
to zero. Touching the UP ARROW will turn the alarm off during this first minute.
However, if the alarm sounds for the entire minute, it will shut-off the sound
automatically. When the alarm first sounds, the timer will start to count up. This lets
the user know how much time has passed since the timer first sounded.
