After setting the alarms, the upper and lower limit symbols (▲▼) will be displayed on the LCD
indicating that an upper and a lower alert value has been set. If the measured temperature
exceeds either limit, the alarm beeper will sound for 1 minute. The alarm beeper icon and the
corresponding arrow will flash. Pressing any button will switch off the alarm.
When the temperature returns to the desired range the audible alarm will stop sounding. The
arrow will remain flashing however to show that the temperature was higher or lower than a set
value at least once in the past. Press the ▲ button to switch OFF the flashing arrow.
