5.3 Lamp Replacement
The Leica BM E utilizes a 7 watt fluorescent lamp with
a life expectancy of 10,000 hours or a 12 watt tungsten-
halogen lamp with a life expectancy of 2,000 hours. When
replacement is necessary contact a qualified service technician.
CAUTION : The glass envelope of the lamp may be extremely
hot. Do not attempt to change the lamp before it is completely
cooled or without wearing adequate skin protection. The glass
should not be handled with bare hands. If the lamp is touched
with bare hands clean the surface with a lens tissue and methanol
prior to installation.
5.4 Electrical Considerations / Equipment Ratings
CAUTION:
As a safety precaution, the power cord has been
grounded to the microscope base. Never use an adapter
between the power cord and the power source; it will render the
grounding feature ineffective.
CAUTION: Risk of electric shock. Removal of the bottom
cover of the microscope exposes hazardous voltages, which
if contacted, could cause injury or death. Please refer servicing to
a qualified service technician.

• 220-240VAC - 250mA/250VAC,Time-Lag
7.0 Anti-Fungus / Mold
Warranty
Fungus and mold are more likely to grow on optical surfaces
in high temperature and high humidity regions. The standard
anti-reflective optical coatings used on the DM E, CM E and
BM E microscopes protect the optical surfaces from these
climatic conditions. Microscopy products from Leica
Microsystems have a history of performing well for long
periods of time without fungus growth. This confidence allows
us to include growth of fungus in your standard Warranty for
DM E, CM E and BM E.
8.0 Notes
Leica assures the quality of our instruments to be free of all faults
in material and manufacturing. We do not, however, cover damage
resulting from improper or careless handling. Contact your Leica
representative for more information.
