If an alarm condition occurred during the Timed Count, a
continuous audio tone will sound, and the ALARM display indicator
will already be on. Tapping the ON/ACK button once will
acknowledge and turn off the continuous tone alarm audio. Doing a
long press (pressing the button and releasing after at least a half
second) to the ON/ACK button will clear the alarm condition and
reset the Count Timer. Alarm audio will sound after the count is
completed if the result is over the alarm threshold.
If other operational modes are available, tapping the MODE button
will move to the next available operational mode.
