General Safety Considerations; Electrostatic Discharge (Esd) - Welch Allyn Connex Service Manual

6 Safety

General safety considerations

• If the system detects an unrecoverable problem, it displays an error message. For
more information see "Troubleshooting."
• To ensure patient safety, use only accessories recommended or supplied by Welch
Allyn. (See the accessories list in the Welch Allyn Connex Integrated Wall System
Directions for use on the user documentation CD or http://www.welchallyn.com.
Always use accessories according to your facility's standards and according to the
manufacturer's recommendations and instructions. Always follow the
manufacturer's directions for use.
• Welch Allyn recommends that only Welch Allyn service personnel or an authorized
repair center perform warranty service. Performing unauthorized service on a device
that is within warranty may void the warranty.

Electrostatic discharge (ESD)

Electrostatic discharge is a sudden current flowing from a charged object to another
object or to ground. Electrostatic charges can accumulate on common items such as
foam drinking cups, cellophane tape, synthetic clothing, untreated foam packaging
material, and untreated plastic bags and work folders, to name only a few.
Electronic components and assemblies, if not properly protected against ESD, can be
permanently damaged or destroyed when near or in contact with electrostatically
charged objects. When you handle components or assemblies that are not in protective
bags and you are not sure whether they are static-sensitive, assume that they are static-
sensitive and handle them accordingly.
• Perform all service procedures in a static-protected environment. Always use
techniques and equipment designed to protect personnel and equipment from
electrostatic discharge.
CAUTION Do not connect more than one patient to a system or connect
more than one system to a patient.
CAUTION Do not operate the system in the presence of magnetic
resonance imaging (MRI) or hyperbaric chambers.
CAUTION Do not autoclave the system. Autoclave accessories only if the
manufacturer's instructions clearly approve it.
CAUTION Electrostatic discharge (ESD) can damage or destroy electronic
components. Handle static-sensitive components only at static-safe
workstation.
CAUTION Assume that all electrical and electronic components of the
system are static-sensitive.
