1.2 Notes on instrument safety
The Stereomicroscopes Stemi DV4 / DR, including original accessories, may only be used for the
applications described in this manual. The manufacturer cannot assume any liability for any
other applications, possibly also involving individual modules or single parts. This also applies to
all service or repair work which is not carried out by authorized service personnel. Furthermore,
this forfeits all the claims against warranty
Always disconnect the power unit from the line before exchanging lamps!
Turning the two zoom/focusing knobs in opposite directions by applying force will result in the
stereomicroscope being damaged.
Dust and dirt can impair the performance of the instrument. Therefore, the instrument must be
protected against these influences as far as possible, and covered with the dust cover if it is not
used for longer periods of time.
1.3 Notes on warranty
The manufacturer guarantees that the instrument has no material and production defects when
delivered. You must inform us of any defects immediately and we must do anything to minimize the
damage. If the manufacturer is informed of such a defect, he is obliged to remove it; it is his decision
whether he does this by repairing the instrument or by delivering an instrument free of any defect. No
guarantee is provided for defects caused by natural wear (this concerns wearing parts in particular) and
improper use.
The instrument manufacturer is not liable for damage caused by faulty operation, negligence or any
other meddling with the instrument, particularly the removal or replacement of instrument components,
or the use of accessories from other manufacturers. This forfeits all the claims against warranty.
With the exception of the work specified in this manual, no maintenance or repair of the microscopes
may be performed. Repairs may only be performed by Carl Zeiss service staff or specially authorized
personnel. Should any defect occur with the instrument, please get in touch with the Carl Zeiss
microscopy service in Germany or your local Zeiss agency.
