s.
MZ16
and MZ16 A stereomi cro-
scopes are
optical instruments which
use
magnification for improved
visual
ization
of objects, their details
and
specimens from technology and
natural sciences.
The
basic outfit, which inc ludes a stand and a light
source, can
be
supplemented with vario
us
modules for photography, TV,
dual
station viewing
and
other applications.
Prohibited
• The use of the instrument in a different manner from
that desc
ribed

uses this user manual can lead to injury, malfunction
and
damage.
• The Leica MS5, MZ6, MZ7s, MZ9s,
MZ12
s,
MZ16
and
MZ16 A stereo-
microscopes must not
be
used for
eye
examinations
and
operations.
•
Do
not fit different plugs.

not dismantle optical systems or mechani -
cal parts unless instructions for doing
so
are given
in
the user manual.

and
trained personnel.
Leica
M Stereomicroscopes -
Safety
concept
Safety
rf'g;ulations
Workplaces with stereomicroscopes facilitate
and
improve the
viewing task, but they
also impose high demands
on
the eyes
and
holding muscles of the user. Dependent upon the duration
of uninterrupted activity, this may
lead to asthenic trouble
and
muscular-skeletal pain
so
that
suitable measures must
be
taken
to reduce the strain:
- perfect design of workplace (see p.
14).
work content and
work process (frequently changing activities).
- detailed introduction of the personnel while considering
ergonomic
and
organizational work-related aspects.
The
ergonomic optics concept
and
the design
ofthe
Leica M
series
aim
at limiting the strain
on
the user to the lowest possi-
ble level.
Direct contact with eyepieces can
be
a potential transmission
path for
bacterial
and
viral infections of the
eye.
Users should
be
made aware of the potential risk of infection.
The
risk can
be
kept at a minimum
by
using individual eyepieces or attachable
eyecups (see
p.16)
.

Ergonomics
The
reasons why
users
often cannot work comfortably with
the 45° tube
are
the differing heights
of
the outfits, the various
accessories
and
working distances,
and
the fact that
the
same
ins
trument
is
often
used
by
several
people
of
differing
builds.
This
problem
can
be
effectively
solved
by
using
the
Leica
ErgoModule™.
Viewing
height,
viewing
angle
If
you
have
problems with
the
viewing configuration
on
your
stereomicroscope,
ask
your
Leica
consultant for the most
ergonomic
Leica solutions.
The
viewing height
is
correct when your
head
and
back
are
comfortably positioned.
•
On
the
Ergo
Tube™,
the viewing
angle
is
adjustable from 10°-50°.
