2 C1.75 Ultrasound System Service Manual
1.5 About the System Software
The SonoSite system contains software that controls its operation. From time to
time, SonoSite provides new software for use with the system.
Transducers that you receive from SonoSite may include new software for the
SonoSite system. This software may be either required or optional.
When the new software is required, you must install it if you wish to use the new
software features (e.g., new transducer). If you choose not to install it, you must
remove the transducer and replace it with one that is compatible with the software
that is currently installed in the system.
When the software is optional, you can either install it or choose to use the existing
software. If you choose not to install the software, the system will prompt you again
whenever the system is started, and whenever the transducer is disconnected and
then reconnected to the system. For more information on software upgrades, refer to
Chapter 4.5, Upgrading the System Software, on page 31
1.6 Software Licensing
Use of the software that you receive from SonoSite is controlled by a license key. A
license key is a number sequence containing exactly 12 decimal digits.
.
License keys are obtained from SonoSite or from its authorized representatives. You
must obtain one license key for each system that will use the new software. Refer to
Chapter 4.6, Obtaining A License Key, on page 33
license key.
Software that you receive from SonoSite may be installed and will operate for a
short period of time without requiring a valid license key. We refer to this period of
time as the “grace period.” The grace period is variable.
When you first install the software, the SonoSite system will prompt you for a
license key. If you have not yet obtained a valid license key, you can elect to use the
software as long as the grace period time has not been fully consumed. We refer to
this mode of operation as “running in the grace period.”
When the system is running in the grace period, all system functions are available.
As you use the system, the grace period is slowly consumed. When the grace period
has expired, the system will not be usable until a valid license key has been entered.
Grace period time is not consumed while the system is powered off or when it is in
“sleep” mode. Whenever the system is running in the grace period, the grace period
time remaining is available on the license update screen. For information on
displaying the license update screen, refer to Chapter 4.6.1.1, Displaying the
System Information Screen, on page 35
CAUTION:

A WARNING describes precautions necessary to prevent injury or loss of life.
A CAUTION describes precautions necessary to protect the products.
2.1 Electrical Safety
This system meets EN60601-1, Class I/internally-powered equipment requirements
and Type BF isolated patient-applied parts safety requirements.
This system complies with the applicable medical equipment requirements
published in the Canadian Standards Association (CSA), European Norm
Harmonized Standard, and Underwriters Laboratories (UL) safety standards. See
Chapter 3.5, System Specifications, on page 22
For maximum safety observe the following warnings and cautions:
WARNINGS:
` Under certain circumstances, the transducer connector and back of the display
enclosure can reach temperatures that exceed EN60601-1 limits for patient
contact, therefore only the operator shall handle the system. This does not include
the transducer face. Patient contact with hot surfaces may result in discomfort or
minor risk of patient injury.
` To avoid discomfort or minor risk of operator injury when handling the
transducer connector, the system should not be operated for more than 60 minutes
continuously in a live-scan mode (as opposed to freeze or sleep modes).
` Do not operate the system in the presence of flammable gasses or anesthetics.
Explosion can result.
.
Chapter 2: Safety 5
` Shock hazards exist if the AC power adapter is not properly grounded. Grounding
reliability can only be achieved when equipment is connected to a receptacle
marked “Hospital Only,” “Hospital Grade,” or the equivalent. The grounding
wire must not be removed or defeated.
` To avoid the risk of electrical shock, before using the transducer, inspect the
transducer face, housing, and cable. Do not use the transducer, if the transducer
or cable is damaged.
` To avoid the risk of electrical shock, always disconnect the AC power adapter
from the system before cleaning the system.
` To avoid the risk of electrical shock, do not use any transducer that has been
immersed beyond the specified cleaning or disinfection level. Refer to the
SonoSite Ultrasound System User Guide for cleaning and disinfection levels.
` To avoid the risk of electrical shock and fire hazard, inspect the AC power
adapter cord and plug on a regular basis. Ensure they are not damaged.
` Connection of peripherals not recommended by SonoSite could result in
electrical shock. Avoid electrical shock hazards by using peripherals and
accessory cables recommended by SonoSite.
` To avoid the risk of electrical shock, use commercial grade peripherals
recommended by SonoSite on battery power only. Do not connect these product
to AC mains power when using the system to scan or diagnose a patient/subject.
Call SonoSite technical support or your local representative for a list of the
commercial grade peripherals available from or recommended by SonoSite.
` The transducer must be removed from patient contact before the application of a
high-voltage defibrillation pulse.
` To avoid the risk of electrical shock to the patient/subject, do not touch the system
battery contacts while simultaneously touching a patient/subject.
CAUTIONS:
` Although your system has been manufactured in compliance with existing EMI/
EMC requirements, use of the system in the presence of an electromagnetic field
can cause degradation of the ultrasound image. If this occurs often, SonoSite
suggests a review of the system environment. Identify and remove the possible
sources of the emissions or move your system.
` Electrostatic discharge (ESD), or static shock, is a naturally occurring
phenomenon. ESD is common in conditions of low humidity, which can be
caused by heating or air conditioning. Static shock is a discharge of the electrical
energy from a charged body to a lesser or non-charged body. The degree of
discharge can be significant enough to cause damage to a transducer or an
ultrasound system. The following precautions can help reduce ESD: anti-static
spray on carpets, anti-static spray on linoleum, and anti-static mats.
` Do not use the system if an error message appears on the image display: note the
error code; call SonoSite technical support or your local representative; turn off
the system by pressing and holding the power switch until the system powers
down (6-10 seconds).
` To avoid increasing the system and transducer connector temperature, do not
block the airflow to the ventilation holes on the back of the system.

Chapter 3: System Overview 11
3.1.1 Transducer
The transducer elements convert the pulser voltage to acoustic energy during the
transmit portion of the ultrasound acquisition cycle. The transducer elements convert
the acoustic echo to voltage in the receive portion of the acquisition cycle. The
system transducers have 64 or more elements. The voltage developed on the
transducer elements is sensed by the acquisition subsystem.
3.1.2 Acquisition Subsystem
The acquisition subsystem consists of a beamformer and an interface to the
transducer. The beamformer times the transmit pulses to focus the acoustic beam.
The beamformer amplifies the low-level echo signal and times the receive
information to focus the receive information.
3.1.3 Processing Subsystem
The processing subsystem interfaces with the beamformer and performs high-speed
processing. The processing subsystem demodulates, filters, detects, and compresses
the signal supplied by the beamformer; it then supplies this data to the display
subsystem.
3.1.4 Display Subsystem

3.1.7 Power Subsystem
The power subsystem provides the system power and protects the hardware from
destructive or unsafe conditions by detecting failures in the system through hardware
and software monitors. Detection of a fault disables the pulser supply, and signals an
error to the control subsystem. The power subsystem includes the battery pack and
the battery charging electronics.
3.2 Components
The SonoSite system components include a hand-carried ultrasound system, a
transducer, and a power adapter. The hand-carried ultrasound system contains the

is functioning properly, the system display requires servicing.
6.4.2 Control Panel
Control panel failures can be identified and verified by going to the patient
information screen and pressing each individual key on the keyboard. Function keys
can be verified by noting their response when pressed.
6.4.3 Trackball
Trackball failures are identified by either intermittent function or loss of control.
The trackball can be cleaned by removing the retainer ring and then removing the
ball.
6.4.4 Main PCBA
The main PCBA can present symptoms that may be difficult to assess. Main PCBA
failures result in “assert codes” that are output to the display. You should note these
assert codes and contact SonoSite technical support, per Appendix B, Service Event
Report, on page 97
and a maintenance icon displayed on the system screen.

CHAPTER 8 Performance Tests
8.1 Overview
WARNING:
` Critical Test Function - A failure of the system function tested in this section
could adversely affect safety or effectiveness of the system. While performing the
steps in this section, verify that the images on the system display and on the
external monitor are acceptable.
• Verify that all controls operate smoothly over their full range and that the system
responds properly.
• To obtain 2D images, SonoSite recommends using the RMI 413A Soft Tissue
Phantom, the RMI 403 GS Multipurpose Phantom, or the equivalent.
• To obtain Power Doppler images, SonoSite recommends using the RMI 425
Doppler Phantom, the RMI 1425A Doppler Phantom, or the equivalent.
• When making penetration measurements on a phantom, apply the phantom
reference value and tolerance to the measurement.
8.2 Test Equipment:
• SonoSite ultrasound system with a C60/5-2 MHz transducer
• RMI 413A Soft Tissue Phantom, the RMI 403 GS Multipurpose Phantom, or the
equivalent
• RMI 425 Doppler Phantom, the RMI 1425A Doppler Phantom, or the equivalent

8.3 Setting Up Performance Tests
To set up the performance tests:
1. Attach the C-60/5-2 MHz transducer to the system.
2. Select general for optimization and OB for exam type.
3. Couple the transducer to the phantom, adjusting gain settings and transducer for
a proper phantom image (e.g., pins are high level echoes positioned in straight
lines; cysts are sonolucent, edges are sharp, and graphite particles of the
phantom are mid grays).
8.3.1 Scan Reference Orientation
1. Verify that the correct transducer name appears in the upper right corner of the
system display.
2. Verify that the scan plane orientation mark in the image located near the skinline
corresponds to element #1 on the transducer. This can be tested by putting your
finger on the probe and running it across the transducer face. Your finger
touching the transducer face as indicated above should show up at the
orientation mark on the image format on the monitor.
3. With the array pointing down and the orientation mark to the operator’s left,
element #1 corresponds with the left side of the array.
8.4 Testing 2D Performance
To test 2D performance:
1. Use a C60/5-2 MHz transducer in 2D mode.
2. Adjust the position of the C60/50-2 MHz transducer on the phantom.
3. Use the 2D system controls to obtain an image that clearly shows both the
horizontal and vertical rows of pins.
8.4.1 2D Image Quality
To test 2D image quality:
1. Verify the ultrasound image appears uniform in both the axial and lateral
direction without any dropouts or intensity variations.
2. Verify the cystic structure at the focal zone is clearly differentiated from the
surrounding tissue and is echo-free; while solid tissue, with numerous echo
sources, appears solid.
78 C1.75 Ultrasound System Service Manual
8.4.2 Axial Measurement Accuracy

first caliper in the menu is active by default.
4. Use the trackball to position one of the calipers.
5. Press select to fix the caliper and enable the other caliper.
6. Use the trackball to move the other caliper. The results update as you move the
caliper, and the measurement is complete when you finish moving the calipers.
(Press select to alternate the active caliper, and adjust the measurement with the
trackball.)
7. You can perform another distance measurement on the image by selecting the
other distance icon and repeating the preceding steps.
8. Measure the distance, center to center, of two pins that are 5-12 cm apart
vertically.
9. Verify the distance measured is within the tolerance listed in Table 8.1
8.4.3 Lateral Measurement Accuracy
To test the lateral measurement accuracy:
1. Perform steps 1 through 7 in Section 8.4.2.
2. Measure the distance, center to center, of the two pins that are 4-10 cm apart
horizontally.
3. Verify the distance measured is within the tolerance listed in Table 8.1
4. Press freeze to return the system to live 2D mode.
