Prepare the adapter. Remove any protective films from the adapter and degrease the two fingers with the alcohol wipe. Remove one protective film only from each adhesive pad and stick one pad on each finger of the adapter, on the inside of the bend.
Choose the position. The adapter goes on the left-hand inside of the helmet, or the right-hand side if you ride on the left, so that the mirror head ends up 60 to 70 mm in front of your eye. If the two mounting fingers do not lie flat against the shell, slightly bend or twist the adapter to suit.
Prepare the helmet. On some helmets you may need to move a piece of Velcro or make a gap behind the lining. The mounting surface must be perfectly smooth and clean, and degreased with the alcohol wipe.
Stick the adapter. Remove the remaining protective films and stick the adapter inside the helmet as shown, keeping strong pressure for two minutes. The adhesive must be left for 24 hours to harden before you fit the mirror.
Clip on the mirror. Now follow the mirror instructions, clipping the mirror onto the adapter instead of onto the glasses.
