Acuson Confidential Overview

OVERVIEW

OBJECTIVE To develop Sequoia MSM fault isolation skills, for Customer

Engineers, International Distributors, and Biomedical Engineers.

PURPOSE Providing field service personnel with a conceptual approach for

isolating failures and performance problems is a critical part of
servicing Sequoia products. Sequoia products benefit from the
state-of-the-art diagnostic software tools which can be used
effectively given the proper training. These state-of-the-art
diagnostic tools are referred to as MSM Tools. Service personnel
must be able to operate and understand MSM Tools in order to
identify and resolve system service problems in a timely manner.

LEARNING MSM TOOLS

INTRODUCTION All Sequoia systems are equippe d with MSM Tools. MSM is an

acronym for Sequoia’s Manufacturing, Service, and Marketing
menu structure. MSM provides the system operators and service
personnel with the appropriate level of access to system features,
diagnostics, configuration settings, and Logs. The MSM Tools are
accessed at the system User Interface (UI) or remotely via modem
by Acuson Help Desk personnel.

The two different levels of MSM diagnostic tools within the Sequoia
system are:

• The first level is referred to as the “User Interfac e” level. The
User Interface level of diagnostic tools can be accessed by
anyone.

• The second level of diagnostic tools is referred to as the
“Service” level. This level of diagnostics can only be accessed by
Acuson trained service personnel.

SERVICE LEVEL Service level access is controlled with an Acuson access number and

password. Acuson access numbers and passwords are generated by

the Acuson Service Department. Sequoia access numbers are
assigned to Acuson trained service personnel by Acuson and are
unique to each person that receives them. Access numbers typically
do not change once assigned to a system or individual.

Sequoia passwords must be used in conjunction with Sequoia
access numbers to gain access to the second level (Service) of the
Sequoia MSM To ols.

NOTE: Sequoia passwords change each day for all Sequoia systems. Sequoia

Access numbers and passwords are sent to eligible service personnel
via e-mail every five to seven days.
