Guarantee Provisions
The data provided in this documentation is intended solely to describe the product
and must not be considered as assured properties. In the interest of users, we are
continually striving to bring our products up to the latest state of the art in technology.
For this reason there may be differences between the product and the product de-
scription and the manual.
If the instructions and recommendations of our documentation are observed, then,
according to our experience, the best possible operational reliability of our products is
guaranteed.
It is virtually impossible for comprehensive documentation to cover every possible
event that may possibly occur when using technical devices and apparatus. We
therefore request that our representatives or we be consulted in the event of any un-
usual incidents and in cases for which this Manual do not provide comprehensive in-
formation.
We explicitly refuse to accept any responsibility for all direct damages that occur as a
result of erroneous usage of our devices, even if no special instructions on this are in-
cluded in the manual.
The documentation has been carefully checked. If the user should find any defects in
spite of this, we request that you inform us as quickly as possible.
We provide a 1 year guarantee for the functioning of the REF542
plus
.
The guarantee provisions are a component of the related contract documents.
