The hatch is located on the back of the unit. It can be opened
and closed using a coin or a large screwdriver (1/4-turn captive
screw). To avoid errors, the symbol on the
power-supply board shows the direction in which the 2 x 3 LR6
1.5 V batteries should be mounted. Make sure that you put the
hatch back properly and close it after changing the batteries.

7.1.2. Replacing the fuse

If "FUS" appears on the digital measurement display during the
start-up phase or when measuring continuity, you must change
the fuse, taking all the necessary precautions when opening
the instrument.
Check that none of the terminals is connected and that the
switch is set to OFF before opening the battery hatch on
the back of the instrument.
It can be opened and closed using a coin or a large screwdriver
(1/4-turn captive screw). The fuse is placed on a fuse carrier
welded to the power-supply board.
To avoid any errors, the text "F-0.63 A" is written next to the fuse
carrier. Make sure that you replace the faulty fuse with fuse of
the same rating and type and then replace and close the hatch.
