6. Lamp replacement
Attention! When installing the lamp (bulb), put it into
socket ensuring that the soldered fitting at its side is
placed in the large recess of the socket (otherwise, the
lamp might be jammed when removing it)!
Note:
When opening the housing (battery replacement), the
lens tip lamp might drop out of the housing. Set the
switch to the ON position in order to clamp the lens
tip lamp.

8. General maintenance
Clean the exterior of the housing with a clean dry
cloth (exception: special cleansing cloths). Do not
use solvents and/ or abrasives to clean the continuity
and circuit tester. Make sure not to contaminate the
battery compartment and the battery contacts with
leaking battery electrolyte. Should such electrolyte
contamination or white deposits occur near the battery
or the battery housing, these must also be removed
with a dry cloth.
Battery disposal:
Do not dispose of batteries with the household
garbage. You as a consumer are legally obliged to
return used batteries. You can return used batteries
to public collection facilities in your community area
or return them to any retail outlet selling similar
batteries. Avoid using batteries containing dangerous
substances!
