NOTICE
Analytical instruments for in vitro diagnostic application involve the handling of human samples and controls which should be considered at least potentially infectious. Therefore every part and accessory of the respective instrument which may have come into contact with such samples must equally be considered as potentially infectious.
BIOHAZARD
The „BIOHAZARD“ warning label must be affixed to instrument prior to first use with biological material !
Servicing Note:
Before doing any servicing on the instrument it is very important to thoroughly disinfect all possibly contaminated parts. Before the instrument is removed from the laboratory for disposal or servicing, it must be decontaminated. Decontamination should be performed by authorised well-trained personnel only, observing all necessary safety precautions. Instruments to be returned have to be accompanied by a decontamination certificate completed by the responsible laboratory manager. If a decontamination certificate is not supplied, the returning laboratory will be responsible for charges resulting from non-acceptance of the instrument by the servicing centre, or from authority’s interventions.

3. Check the contents of the packing box for the following:
-HUMAREADER HS
-user manual
-service manual
-power cord,
- RS-232 serial cable
-touch pen
- spare bulb
-mouse
-spare fuse
 (QYLURQPHQWDOUHTXLUHPHQWV
Select a location not exposed to direct sunlight. The HUMAREADER HS should be placed on a smooth surface with sufficient working space. The front edge of the instrument should be close to the edge of the table. Avoid excessive vibrations (e.g. from a centrifuge).
Note: the ambient working temperature should be between 10°-40°C, with humidity between 20%-85%.
In order to ensure the proper functioning of the instrument, the following environmental conditions must be avoided:
- large temperature fluctuations
- temperatures outside the recommended range
-dust
- proximity to equipment that generates an electromagnetic field
The mains supply must fulfill the following requirements:
- AC90V-AC250V
- 50-60Hz
- 120VA
Note:
- The AC mains supply must be well earthed
- Grasp the plug itself, not at the power cord, to unplug the power cord.
