a) The Gasman will demonstrate
the alarm LEDs, sounder,
vibration alerts, and the
operator display screen. The
sounder may be silenced by
pressing the button.
The Gasman screen will show the following display during the
warm up sequence. This will take approximately 20 seconds.
Note: these screens may differ depending on what sensor is being used.

confirm screen: the display will alternate between ‘ZERO’ and
‘????’. Press the operator button with a single click to confirm
