4.3.1  Removing the cell 
For a safe removal of the cell from the cell compartment proceed as follows.
-  While opening the shutter with one hand, prevent the cell 
from falling down by placing two fingers of the other hand 
underneath of it. 
-  In most cases the cell will be set free as soon as the shutter 
has been opened completely and can be taken away from 
the cell compartment.
  In case the cell didn’t come loose although the shutter is 
already completely open, hold the cell in place with two 
fingers. 
-  Press with one finger against the metal bar at the inside of 
the shutter to set the cell free.
-  The cell is released and can be taken away from the cell 
compartment.
