When testing the control module, lay the control module down flat to check the white light illumi-
nating the pressure gauge and to check if the graphical display and the analog gauge match within
a 10 bar range.
Manual alarm can be reset using the green buttons on the control module.
Verify proper function of the HUD, control module, power module, and low pressure warning
device by observing the control module gauge and display when the alarms sound. Perform this
test with a full cylinder.
