Electromagnetic Interference 
Electromagnetic Interference (EMI) between wireless electronic 
transmitting devices and medical equipment can cause degradation 
of the ultrasound image. The system is in compliance with existing 
EMI/EMC requirements. However, the use of this system in proximity 
of an electromagnetic field can cause degradation of the ultrasound 
image at times. Review the environment in which the system is being 
used, to identify possible sources of radiated emissions. Sources of 
these emissions can be from electrical devices used in the same or 
adjacent room. Communication devices that transmit or receive RF 
signals; cellular phones, pagers, radio, TV, or microwave transmission 
equipment located nearby can cause these emissions. If EMI from an 
outside source is causing disturbances, you may need to relocate your 
system. Electrosurgical units (ESUs), MR=’s and many other medical 
devices introduce radio frequency (RF) electromagnetic fields to the 
environment. Because ultrasound imaging frequencies are in the RF 
range, ultrasound transducer circuits are also susceptible to RF 
interference. For example, the noise generated by an ESU in use can 
easily impair or eliminate the ultrasound’s ability to capture an image. 
Some measures to reduce the chance of EMI interference include:  
 Three-meter rule – no powered on cell phones, or pagers within 
three meters of the system while in operation. 
 Locate the system away from other imaging equipment such as 
MR=’s that produce strong electromagnetic fields.  
Electrostatic Discharge ESD Precautions 
Electrostatic discharge (ESD), commonly referred to as a static shock, 
is a naturally occurring phenomenon. Electrical charges naturally 
build up on individuals and can create static shocks. The human body 
can build up a charge as high as 25,000 volts, therefore a discharge 
from a system user or patient to the ultrasound system can cause 
damage to the system or transducers. Digital ICs are particularly 
vulnerable. Low humidity is a condition that favors the build-up of 
electrostatic charge.  
The following are the most common causes of ESD: 
 Moving equipment 
 Moving people

 Low humidity (hot and dry conditions) 
 Improper grounding 
 Unshielded cables 
 Poor connections 
Use the following precautions in order to reduce ESD: 
 Wrist straps 
 Antistatic mats 
 Antistatic spray on carpets or linoleum 
Before handling a board or you can touch a grounded surface such as 
the power supply housing to discharge any built-up charge. 
Fire Safety 
The following general fire safety practices are relevant for all 
electrical equipment:  
 If there is any evidence of smoke or fire disconnect system power 
immediately. 
 On electrical or chemical fires use only extingushers that are 
specified for this use. Using water or other liquids is very 
dangerous and can lead to injury.  
General Cautions 
The following are general cautions that apply to all ultrasound 
systems: 
 Batteries must be handled as hazardous waste. Check that the 
cases are intact and the terminals are clean. Follow your facilities 
procedures regarding disposal should they become damaged.  
 If the system has been stored below 10°C allow it to reach room 
temperature before connecting or turning on to prevent 
damaged caused by internal condensation. 
 System transductors cannot be cleaned/decontaminated by any 
sort of heat process. Refer to manufacturer’s specifications and 
hospital procedures for the particular transducer.

Module 7 Troubleshooting 
This module covers common troubleshooting tools and procedures 
for the E9 systems. 
Normal Power On/Boot Sequence 
The following describes the normal power on/boot sequence for the 
E9 systems  
The system has two power switches: 
 
 The Circuit Breaker Switch is located on the back of the system 
next to the power cord plug-in. This allows to the system power 
supply to power up but does not turn on the system itself. 
 The On/Off button is located on the user control panel at the 
front of the system. This switch initates system Bootup. 
Connect AC (mains) Power to the Vivid E9/Logiq E9 
Before connecting AC Power to the ultrasound unit you should 
perform the following preliminary checks of the power cord, voltage 
levels and compliance with electrical safety requirements. 
 Ensure that the wall outlet is of appropriate type, and that the 
Mains Circuit Breaker is turned off. 
 Verify that the power cable is without any visible scratches or any 
sign of damage. 
 Verify that the on-site mains voltage is within the limits indicated 
on the rating label near the circuit breaker on the rear of the 
unit. 
 Connect the Power Cable’s to the power Inlet at the rear of the 
unit and lock the plug into position with the ACC Clamp. 
Note: a probe should be 
connected to the system 
or the system will boot up 
in no mode. 
Note: Do not cycle the 
circuit breaker ON-OFF-
ON in less than five 
seconds. When turning 
the circuit breaker off you 
must wait until the 
ON/OFF button is no 
longer lit. The system 
should be completely de-
energized before turning 
the circuit breaker ON 
again. 
Note: The E9 functions on 
voltages from 100-240V 
and 50 or 60Hz. If using 
220 V power, a center 
tapped power source is 
required.

Turn System ON 
Switch ON the Mains power circuit breaker at the rear of the unit. The 
control panel ON/OFF button should become amber. You should also 
hear a “click” sound from the relays in the AC Power supply and the 
unit is ready to boot. The ON/OFFbutton will remain amber. 
Press once on the ON/OFF button on the Operator Panel to boot the 
unit. The ON/OFF button turns green when it is pressed. 
During a normal boot sequence, you will notice that: 
 The unit’s ventilation fan starts on full speed, but slows down 
after a few seconds. 
 Power is distributed to the peripherals, Operator Panel (Console), 
Monitor, FEP and BEP. 
 Back end processor is turned ON and begins to load the software. 
 The Start Screen displays on the monitor. 
 A start-up bar indicating the time used for software loading, is 
displayed on the monitor. 
 The software initiates and sets up the front end electronics. 
 The backlight in the keyboard is lit. 
 When the software load is complete the 2D screen is displayed 
on the screen, as long as a probe has been connected, or a No 
Mode screen is displayed, indicating that no probe has been 
connected. 
Sleep Mode 
Sleep Mode is intended to reduce the boot up time (is less than 120 
seconds) on portable studies. Sleep mode saves all memory content 
in the hard drive and shuts down. When booting up, memory content 
is then restored from the HDD. 
 2D Screen 
Sleep mode is not a 
substitute for a regular 
shutdown. Shutdown the 
system completely at least 
once a day to prevent 
performance issues.

Troubleshooting Log/Image Capture 
If the system should malfunction you can capture logs by pressing the 
Alt+D keys simultaneously. This Alt+D function should respond even 
in the event of a system lock-up. 
This will collect a screen capture of the monitor, system presets and 
several log files in a date and time stamped “.zip” file. 
Depending on the system the Alt+D function collects a screen capture 
of the image monitor, user-defined presets, and the following logs: 
 Keyboard Shadow Log 
 Error Logs 
 Crash Log 
 Vital Product Data 
 DICOM Logs 
 Windows Event Logs 
 Diagnostic Logs 
 Service Logs 
When Alt+D is pressed you will need to enter the following 
information in the window that opens: 
 System ID serial number. 
 Software version. 
 System Date and time of occurrence. 
 Sequence of events leading to issue. 
 Is the issue repeatable? 
 Imaging mode, probe, preset/application. 
 Did the system lock-up? 
 Select the destination for the log capture either formatted 
storage media or the Service directory for remote viewing 
through InSite ExC. 
To save to a CD/DVD select CD/DVD Recordable as the destination, 
otherwise the data will be written to the default Export/Service 
directory on the hard drive. The Export/Service directory is only used 
for InSite ExC. 
Click the Store button. 
The screen capture is a 
bitmap which eliminates 
the possibility of artifacts 
from compression. 
On later system versions 
for CD/DVD; the system 
will automatically format 
if you insert an 
unformatted disk, gather 
logs and write it out to the 
disk.

Trouble Shooting Network Issues 
The network tools include Wireshark which is a “network sniffer” that 
displays network traffic between the ultrasound system and other 
devices. It is useful for debugging connectivity issues. Its output can 
be saved to a file. 
 To display the Wireshark interface press Alt-N: 
 
 In the Capture/Interfaces window press the Options button that 
corresponds to the IP address. 
 
 Uncheck Capture packets in promiscuous mode and Press 
Start. 
 Depending on the software version enter dcm or dicom. In 
the filter bar. Wireshark indicates whether it accepts one or the 
other by turning the Filter dialog background green. 
This network sniffer tool is 
available in both systems.

 Press Apply. Once Wireshark displays DICOM traffic, you can 
select an individual line and expand the DICOM tree in the lower 
frame to view DICOM-specific data. 
 
 Capture Restart clears the current traffic display, in preparation 
for the next DICOM exchange. 
 Entries with “Reject” or “Abort” indicate issues. 
 To save the network traffic currently displayed, stop the capture 
and press File / Save As. In the pop-up, select a destination drive 
or folder, name the file, select both “All packets” and 
“Displayed” under Packet Range, and press Save.

This saves the D=COM traffic in a file with suffix “.pcap”, which can be 
analyzed by Wireshark or a similar network sniffer. 
Trouble Shooting Operator Panel Issues 
This section covers common operator panel issues. 
No Audio 
Check volume settings in the application and also in Windows. 
Use headphones, (the type that you use on a personal CD player or a 
laptop) to test the audio output directly from the back of the BEP. 
 If no Audio is present on the BEP, reload software. If the problem 
persists, replace the BEP. 
 If Audio is present, follow the audio signal to the OP Panel (the 
audio amplifier is located in the upper OP panel). The Audio 
output from the BEP goes to the Internal I/O and from there to 
the OP Assembly (use an adapter to plug the headphones to the 
RCA outputs of the Internal I/O). If Audio outputs are working, 
replace Upper OP Assembly. Otherwise replace Internal I/O

board. 
 Always measure the speakers’ impedance; it should measure 
approximately 7 ohms. If speakers are bad, it is possible that the 
amplifier on the Upper OP Assembly might be defective, too. 
No Video on LCD Display 
 If the video is too dim, has dimmed areas or there is no video at 
all, replace the HV LCD inverter. 
 Check the cabling within the system. 
 If the HV LCD inverter is burnt, there is a possibility that the 
Digital Video Card on the PC also got damaged; in that case you 
can replace the Video Card. 
 Replace the Video Adapter inside the BEP. 
 Replace the Back End Processor if the problem continues. 
 Replace the Upper Panel Assembly. 
Wrong Key Activated on the Touch Panel 
 Calibrate touch panel. 
 Replace Upper Panel Assembly. 
Touch Panel Not Responding 
 Calibrate the Touch Panel. 
 Reload software. 
 Replace Upper Panel Assembly. 
Probe Recognition 
Check all the probes on all the ports. Remove all the probes, and then 
check each probe singly in every port. 
 
 If the problems persist with all the probes, replace the GRLY
