Cover Replacement
1. Unscrew the four screws using a 2.5 mm Allen wrench.
2. Remove the cover. The cover will remain attached to the body because of the gas-
ket. To unmount it properly, it is recommended to gently lever the cover from its
corners  using  a  flat  blade  screwdriver  between  the  cover  and  the  body  of  the
reader. See Figure 49 and Figure 50.
