Ans: If such situation happened, please check welding helmet by following procedure step by step: Press “TEST” button located on filter lens, – Filter changes from a clear state to a dark state immediately after pressing “TEST” button, and then changes back to be a clear state. That means battery is working. Please adjust “SENSITIVITY” knob to “high”. – “Low Battery” light flashing for a second; or filter doesn’t change to dark status after pressing “TEST” button, it may “low battery”. Please change the battery immediately.
