PREFACE

Acuson is pleased to welcome you to the Sequoia® ultrasound
systems. The Sequoia systems are special-purpose machines
designed for general radiology, obstetrics, gynecology, cardiology,
and/or vascular exams.

Acuson systems have an exceptional record of dependability, and
Acuson has a customer service network ready to respond to the
needs of our customers.

For information on Acuson’s service offerings, please consult the

of basic test equipment (DVM, oscilloscope, etc.) and with basic
ultrasound theory.

Use this manual when servicing a Sequoia ultrasound system.

KEY CONVENTIONS This manual uses several conventions to refer to controls on the

system. The following list shows the conventions and their
descriptions.

WARNING!

This manual is intended for use by trained service personnel. There are
lethal voltages inside Sequoia systems. Bodily harm, possibly death,
and damage to the system may result from untrained individuals
opening the system.

OTHER SEQUOIA
SYSTEM MANUALS

In addition to this manual, the following manuals are available for
the Sequoia system:

Acuson Sequoia

® Ultrasound System User Manual

The User Manual provides information used regularly to perform
ultrasound exams. It explains how to operate the standard and
optional features of the Sequoia system for radiology, obstetrics,
cardiology, gynecology, and/or vascular exams, including the use
of special purpose transducers such as endocavity transducers,
transesophageal transducers, and interoperative transducers. It
explains how to use transducer needle guides to perform biopsies.
It also contains setup information, which is used less frequently.
The User Manual addresses the reader who is familiar with
ultrasound techniques; therefore, it does not include sonography
training or clinical procedures.

Acuson Sequoia® Ultrasound System Reference Manual

The Reference Manual consists of the Safety Manual, the Tr a ns d u ce r
Specifications Manual, and the Administrator Manual.

• The Safety Manual explains system and transducer safety
precautions and maintenance procedures.

• The Tr an s du c er S pe c if ic at io ns M an u a l lists technical information
about the individual transducers, including power value tables
for all Acuson transducers.

• The Administrator Manual describes system and calculation
package setup options. In addition, it contains information on
setting up and operating peripheral devices with the Sequoia
system.

WARNING!

A Warning alerts the user to a potential risk of death or serious injury
to the user or patient.
