CAUTIONS:
` Although your system has been manufactured in compliance with existing EMC/
EMI requirements (EN60601-1-2), 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.
6 C1.9 PLUS Ultrasound System Service Manual
` 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, anti­static 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 or your local representative; turn off the system by pressing and holding the power switch until the system powers down.
` 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

3.1 Theory of Operation

The SonoSite ultrasound system has seven major functional groups: the transducer, the acquisition subsystem, the processing subsystem, the display subsystem, the control subsystem, the user interface subsystem, and the power subsystem.

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. Also, the transducer elements convert the acoustic echo to voltage in the “receive” portion of the acquisition cycle. The system transducers have more than 64 elements. The acquisition subsystem senses the voltage developed on the transducer elements.

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. Also, the beamformer amplifies the low-level echo signal and times and focuses the “receive” information.

3.1.3 Processing Subsystem

The high-speed processing subsystem interfaces with the beamformer. The processing subsystem demodulates, filters, detects, and compresses the signal supplied by the beamformer. Next, it sends this data to the display subsystem.

3.1.4 Display Subsystem

The display subsystem converts the detected ultrasound data into picture elements (pixels). The software user interface graphics are combined with the ultrasound information and converted to a video stream. The external video ports support NTSC and PAL format.

3.1.5 Control Subsystem

The control subsystem consists of the central processing unit, program and video memory, permanent image storage and retrieval memory, and a connection to the user interface keys. The control software includes the acoustic power and intensity software power group monitors, and a beamformer monitor. This software makes the system operate within acoustic power and intensity limits, which guarantees a level of patient safety.

3.1.6 User Interface Subsystem

The user interface subsystem comprises the software user interface and the form factor. The software user interface is the interaction between the user and the screen layout components. The form factor is the device’s physical attributes: buttons, location and grouping of buttons and the device size, shape, and weight. Dedicated controls, or often-used features, are grouped according to user workflow.
12 C1.9 PLUS Ultrasound System Service Manual

3.1.7 Power Subsystem

The power subsystem provides power and protects the hardware from destructive or unsafe conditions. This subsystem’s hardware and software monitors detect failures in the device. Upon detecting a fault, the system 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 are identified in Chapter 1, section 1.2.

CHAPTER 4 Setup and Operation

WARNING:
` CRITICAL TEST FUNCTION - Skipping the functional tests in this procedure
could adversely affect safety or effectiveness of the system.
Operation of the SonoSite ultrasound system can be found in the user guide provided with each system.

4.1 Connecting and Removing Transducers

The system comes with one or more transducers. Only one transducer can be connected to the system at a time.
WARNING:
` The transducer connector can become hot during operation. This is normal.
Operate the system in the SiteStand mobile docking station or on a flat, hard surface to allow air flow past the connector.
CAUTION:
` The electrical contacts inside the system transducer connector may be damaged by
foreign material or by rough handling. Do not touch the electrical contacts. Keep foreign material out of the connector. Keep a transducer connected to the system whenever possible.
To connect the transducer:
1. On the transducer connector, pull the latch up and rotate it clockwise until it
snaps to a stop (Figure 4.1). The latch should be easy to move. Do not force the latch.
2. Align the transducer connector with the connector on the rear of the system and
insert it by pushing the transducer connector into the system connector. The transducer connector should be easy to insert. Do not force the transducer connector.
3. Turn the latch counterclockwise until it snaps to a stop.
Chapter 4: Setup and Operation 21
4. Press the latch down until it snaps into place, securing the transducer connector
to the system.
Transducer connector Transducer connector latch
Figure 4.1 Connecting the Transducer
To remove the transducer:
1. On the transducer connector, pull the latch up and rotate it clockwise until it
snaps to a stop (Figure 4.1).
2. Carefully pull the transducer connector away from the system.

4.2 Turning the System On and Off

When turning power on or off, you must push and hold the Power switch for approximately one second before the system responds.
