Confidence signals
In normal Run mode, Gasman will emit a short beep accompanied by a blue LED flash every 10
seconds and the OK icon flashes to show operational health. These confidence signals can be
disabled using the PC software.
The Gasman alarm is set to latch by default. The unit will still continue in alarm mode even
when the gas level returns to normal, until the button is pressed and the alarm is cleared.
