•
Do not clean the spirometry tubes with high pressure air or O
2
flushing while the
spirometry tubes are connected to Patient Spirometry connector. High differential
pressure may damage PVX unit pressure transducers.
Special components
•
Special components are used in these monitors that are vital to assure reliability and
safety. GE Healthcare assumes no responsibility for damage, if replacement components
not approved by GE Healthcare are used.
Batteries
Refresh the batteries completely every six months.
To replace the batteries safely, please refer to the service instructions in this manual.
•
Do not short-circuit the battery terminals, this may produce a very high current, which
will damage the battery.
•
Do not dispose of the battery into open flame, nor put the battery near fire, as it may
explode.
•
Do not dismantle the battery.

Storage and transport
Do not store or transport the monitor outside the specified temperature, pressure and humidity
ranges:
Temperature
-10...+50 °C/14...122 °F
Atmospheric pressure
660...1060 hPa/500...800 mmHg/660...1060 mbar
Relative humidity
10...90% noncondensing
For display specific environmental requirements see specifications in the “Display” slot.
1.2.2 ESD precautionary procedures
•
To avoid electrostatic charges building up, it is recommended to store, maintain and use
the equipment at a relative humidity of 30% or greater. Floors should be covered by ESD
dissipative carpets or similar. Non-synthetic clothing should be used when working with
the component.
•
To prevent applying a possible electrostatic discharge to the ESD sensitive parts of the
equipment, one should touch the metallic frame of the component or a large metal object
located close to the equipment. When working with the equipment and specifically when
the ESD sensitive parts of the equipment may be touched, a grounded wrist strap
intended for use with ESD sensitive equipment should be worn. Refer to the
documentation provided with the wrist straps for details of proper use.
ESD precautionary procedure training
It is recommended that all potential users receive an explanation of the ESD warning symbol
and training in ESD precautionary procedures.
The minimum contents of an ESD precautionary procedure training should include an
introduction to the physics of electrostatic charge, the voltage levels that can occur in normal
practice and the damage that can be done to electronic components if they are touched by an
operator who is electrostatically charged. Further, an explanation should be given of methods
•
A lithium battery on the CPU Board. Dispose of the faulty IC containing the battery
according to local regulations.
