CAUTION!
Damage to the instrument due to servicing duties that have not been carried out or
have been carried out improperly.
If servicing duties are not carried out according to the servicing schedule or non-original
SIGRIST spare parts are used, this can lead to damage to the instrument or measuring errors.
In this case, SIGRIST-PHOTOMETER AG accepts no warranty claims made by the customer
and is not responsible for any subsequent costs. To avoid this situation, please adhere to the
following steps:

Carry out servicing duties according to the servicing schedule (Section 9.1).

When carrying out servicing duties, use original SIGRIST spare parts according to the
spare parts list (Section 15). The use of third-party spare parts requires the written ap-
proval of SIGRIST-PHOTOMETER AG.

If the instruments are subjected to heavy use or exposed to severe environmental condi-
tions, servicing duties must be carried out more often as required. Wear parts in particu-
lar must be replaced more often depending on the circumstances.
