AlcoSensor Operation / Problems
Alco-Sensor III(version without the red mouthpiece ejector button)

Note that the current version Alco-Sensor III (with red mouthpiece ejector button) displays the message"bat"for low battery.
Problem: Display keeps cycling back to temperature display (i.e., "25 ºc") without going to the message "TEST."
