►

Remove the cover (item 1 in Fig. 5) from the battery compartment on the back of the mo-
bile reader. To do this, pull the cover down as far as it will go, then lift off.

NOTE

Make sure that the polarity symbols on the batteries match the polarity symbols in the 
battery compartment. The mobile reader may be damaged if the batteries are wrongly 
inserted.
