Important information
This Service Manual contains vital warning and safety information.
This instruments are intended to be used only for the specialized purpose described
in the instructions. The most important prerequisites for use, operation, and safety
are explained to ensure smooth operation. No warranty or liability claims will be
covered if the instrument is used in ways other than those described or if the
necessary prerequisites and safety measures are not observed.
The instrument may be operated only by persons whose qualifications enable them to
comply with the safety measures that are necessary during operation of the
instrument.
Suitable protective equipment, like laboratory clothing, protective gloves, protective
goggles and if necessary mouth protectors, must be worn to prevent direct contact
with biological working materials. In addition, a face mask is required if there is a
risk.
Adjustments and maintenance performed with removed covers and connected power
may be attempted only by a qualified technician who is aware of the associated
dangers.
Instrument repairs are to be performed only by the manufacturer or qualified service
personnel.
Only accessories and supplies either delivered by or approved by Roche are to be used
with the instrument. These items are manufactured especially for use with this
instrument and meet the highest quality requirements.
Operation of the instrument with solutions whose composition is not consistent with
that of the original solutions can negatively affect, above all, the long term
measurement accuracy. Deviations in the composition of the solutions can also
decrease the service life of the electrodes.
The quality control requirements must be completed at least once daily for safety
reasons. Because accurate measurement results depend not only on the proper
functioning of the instrument, but also on a number of other factors (such as
preanalytics), the results produced by the instrument should be examined by a
trained expert before subsequent decisions are reached that are based on the
measurement values.
