1. Slide in the inner protection screen on the
inner side of the autodarkening welding filter as
shown in figure (1.).
2. Gently fold the printed circuit board of the
external control behind the filter so that it is
positioned inside the helmet shell before you.
Insert the filter in its opening. Begin by insert-
ing the filter at the bottom, so that it clicks in
the bottom clip (2.a); then push in the top part
so that it clicks into the top clip (2.b).
3. Insert the external protection screen into its
position with four side holders. Hold the protec-
tion screen with your thumb and middle finger
and place it on the side of your thumb into the
slots of both side holders. The indent of the
helmet shell provides the necessary space for
your thumb (3.a). With your middle finger bend
the protection screen and with the aid of the
other fingers place it in both side slots (3.b).
4. Close the helmet shell with the external frame.
Insert the bottom two pins in the lowest two
openings of the helmet shell and push the top
part of the frame into the helmet shell so that
the two upper pins click in the pin openings on
both sides (2x click) (4.).

housing in its opening on the exterior side of
the helmet shell (5.).
6. Insert the electronic circuit board with poten-
tiometers in the middle part of the external
control housing (6.).

4 knobs to the potentiometers from the outside.
Take care, that the knobs are inserted cor-
rectly. Check that the final position of the marks
on the knob correspond to the printing on the
