The magnetic component is required to determine visor position being in an open or closed state. It is
mounted using the right-side visor frame button to secure in place.
1. With the visor frame in the down position (M-100, M-200 & M-300), release the visor frame
right-side button by pushing it outward from inside the visor frame, one “click” (Figure 3). Move
the visor frame to the up (open) position to seat the magnet housing (Fig. 5b). If using the M-400,
it may be easier if the visor frame is in the up (open) position to release the button and seat the
magnet housing.
NOTE: The visor itself does not need to be removed in order to place the magnetic component.
2. With the visor in the up (open) position, install the magnet by inserting between the visor frame
and button snapping it in place. The magnet should make an audible “click” when fully seated in
the frame. (figure).
3. Push visor frame button closed to lock visor back in place. The button should make an audible
“click” when fully seated in the frame (Fig. 5c). Ensure visor buttons are firmly secured and flush
to the visor frame (Fig. 5d). If the buttons do not seat flush to frame, remove and reinsert.
4. Ensure the visor gasket is present and securely inserted into the groove in the top of the visor
frame (See M-921 in this section).
The Headtop Peripheral can be inserted once the carrier has been installed (Figure 4.1). With the
headgear upside down, position the Headtop Peripheral behind the suspension and insert into the carrier
with the battery cover and LED side facing inward to the helmet until it is fully seated (Figures 5.1 &
5.2).
