Due to legal requirements, your P-DISC NO2 needs to be placed in the bottom right corner of your windscreen (on the passenger side).
Firstly, ensure that the inside of your windscreen is clean and dry. A clean windscreen that’s not too cold, preferably over 15 degrees, is the ideal condition for installation.
Leave the magnets attached to the P-DISC NO2, and remove the protective foil from the magnets, exposing the adhesive. With the magnets still attached to the P-DISC NO2, press it against the windscreen to mount the P-DISC NO2 in the desired location.
If you need to adjust the settings of P-DISC NO2, replace the batteries, clean the windscreen, or anything similar, the P-DISC NO2 can easily be removed and put back in place thanks to the magnetic mounts.
