Overview
Field service of this unit is limited to functional checks, cleaning, updating the interface software, replacement
of certain items during preventive maintenance, and replacement of the interface PCBA, the gas unit (OEM

Only trained personnel with appropriate equipment should perform the tests and repairs outlined in this
chapter.
Perform a functional check before starting preventive maintenance, to identify any issues requiring corrective
maintenance. A functional check should also be performed after the preventive maintenance procedure.

Caution:
• Observe precautions for handling electrostatic-sensitive devices!
• Cleaning, preventive maintenance, and safety checks should be performed annually and
following any product disassembly/assembly. Preventive maintenance and safety checks must
be performed by trained personnel only.
Note:
• Never touch electrostatic-sensitive electronic components without following proper anti-static
procedures, including the use of an ESD wrist band and mat. An electrostatic discharge from your
fingers can permanently damage electronic components.
• All static-sensitive electronic components are packaged in static-shielding bags. Retain the bag for
repackaging the component, should you need to store it or return it to Spacelabs Healthcare for any
reason.
