Caution!
Through activating to the grounding connec-
tion (earth screw at the back of the stand)
ancillary equipment with its own and/or ex-
tra power supply may be brought to the
same ground wire potential. For connections
without a ground connector, Leica Service
must be consulted.
Caution!
Never use any fuses as replacements other
than those of the types and the current rat-
ings listed here. Using patched fuses or
bridging the fuse holder is not permitted.
The use of incorrect fuses may result in a
fire hazard.
Caution!
The microscope's electrical accessory com-
ponents are not protected against water.
Water can cause electric shock.
Caution!
Protect the microscope from excessive tem-
perature fluctuations. Such fluctuations can
lead to the accumulation of condensation,
which can damage the electrical and optical
components.
Ambient temperature: 15-35°C.
Caution!
Before exchanging the fuses or lamps, be
absolutely certain to switch off the main
power switch and remove the power cable.
