LME EQUIPMENT

The release pushbutton on the equipment is the main component for accessing all the diagno-
stic functions (activation and deactivation) as well as for releasing the control and checking
device. The release pushbutton has a multicoloured led which indicates the state of the control
and checking device during operation and when the diagnostic function is in use.
