I have a speedglas helmet of the 9000? variety, however i have no instructions for it. The problem i am having is that when in use the respirator unit beeps. On the top there are three L.E.D. on for power on, one for low battery and another which i assume is a flow indicator. it has a symbol of a fan with a cross over it. this also comes on when it beeps. I have fitted a new filter, and also made sure the battery is fully charged, yet it still happens. Does anyone know what is going on and how to solve it?
Thanks
