The instruments and accessories described
in the manual have been checked for safety
or possible risks. Before making any altera-
tions to the equipment or combining it with
non-Leica components in a way not de-
scribed in this manual, consult the Leica
agency for your region or the main factory in
Wetzlar! Any guarantee will be rendered in-
valid if the instrument is opened or modified
in any way by unauthorised persons or if the
instrument is used in another way than the
one described in these instructions!

Setting the mains voltage
Microscopes with mechanical focusing (42.12)
are automatically adapted to the local mains
voltage in a range of 120 % / 230 % V. For
microscopes with motor focus (RE and RXE
models, Fig. 44), however, the selector switch at
the back of the microscope (2.6) must be set.
Attention:
For external power units the mains voltage
should always be set according to the sepa-
rate instructions supplied.
Electric safety
To ensure that the microscope and
accessories are in a perfectly safe condition,
please note the following advice and
warnings: The mains plug must only be
inserted into a grounded outlet. If an
extension cord is used, it must be grounded
as well. Using the ground connection (2.4),
any accessories connected to the
microscope which have their own and/or a
different power supply can be given the same
ground conductor potential. Please consult
our servicing personnel if you intend to
connect units without a ground conductor.
