2. Remove the transport protection film from the clear view cover (Fig. 20-1 no. 1) if
available.
Tip:
The protective film will harden upon exposure to UV radiation and possibly cannot
be removed later without leaving some residue. Readability may be strongly impai-
red due to the changes to the protective film.
New clear view covers can be purchased from NIVUS for an extra charge and can
be easily replaced by the user.
