zIt is important for the hospital or organization that employs this equipment
to carry out a reasonable service/maintenance plan. Neglect of this may
result in machine breakdown or injury of human health.
zNever use combustible gas (e.g. anesthetic) or combustible liquid (e.g.
ethanol) around the analyzer. Otherwise, the risk of explosion may exist.
zContacting exposed electronic components while the equipment is attached
to power can cause personal injury from electric shock or damage to
electronic components. Power down before removing covers to access
electronic components.
zConnect the analyzer to a socket having sole fuse and protective switch. Do
not use the same fuse and protective switch with other equipment (e.g. life
supporting equipment). Otherwise, the equipment failure, over current or
impulse current that occurs at the startup moment may lead to tripping.
zTo prevent personal injury during the maintenance, keep your clothes, hairs
and hands from the moving parts, such as sample probe, clipper and
piercer.
zPossible mechanical movement of the warned position may lead to personal
injury during the normal operation, removal and maintenance.
zBe sure to dispose of reagents, waste, samples, consumables, etc.
according to government regulations.
zThe reagents are irritating to eyes, skin and diaphragm. Wear proper
personal protective equipment (e.g. gloves, lab coat, etc.) and follow safe
laboratory procedures when handling them in the laboratory.
zIf the reagents accidentally spill on your skin, wash them off with plenty of
water and if necessary, go see a doctor; if the reagents accidentally spill into
your eyes, wash them off with plenty of water and immediately go see a
doctor.

zFor problems not mentioned in the service manual, contact Mindray
customer service department for maintenance advice.
zTo prevent personal injury or damage to equipment components, remove
metal jewelry before maintaining or servicing electronic components of the
equipment.
zElectrostatic discharge may damage electronic components. If there is a
possibility of ESD damage with a procedure, then do that procedure at an
ESD workstation, or wear an antistatic wrist strap.
zThis equipment must be operated by skilled/trained medical professionals.
zSamples, controls, calibrators and waste are potentially infectious. Wear
proper personal protective equipment (e.g. gloves, lab coat, etc.) and follow
safe laboratory procedures when handling them in the laboratory.
zAll the analyzer components and surfaces are potentially infectious.
zTake proper protective measures for operation or maintenance.
zThe sample probe tip is sharp and may contain biohazardous materials.
Exercise caution to avoid contact with the probe when working around it.
