Safety Considerations
1-3-1 Introduction
The following safety precautions must be observed during all phases of operation, service and repair of 
this equipment. Failure to comply with these precautions or with specific warnings elsewhere in this 
manual, violates safety standards of design, manufacture and intended use of the equipment.
1-3-2 Human Safety
Operating personnel must not remove the system covers. 
Servicing should be performed by authorized personnel only. 
Only personnel who have participated in a LOGIQ™ 9 Training are authorized to service the equipment.
1-3-3 Mechanical Safety
WARNINGWARNINGWHEN THE UNIT IS RAISED FOR A REPAIR OR MOVED ALONG ANY INCLINE, USE 
EXTREME CAUTION SINCE IT MAY BECOME UNSTABLE AND TIP OVER.
WARNINGWARNINGULTRASOUND PROBES ARE HIGHLY SENSITIVE MEDICAL INSTRUMENTS THAT 
CAN EASILY BE DAMAGED BY IMPROPER HANDLING. USE CARE WHEN 
HANDLING AND PROTECT FROM DAMAGE WHEN NOT IN USE. DO NOT USE A 
DAMAGED OR DEFECTIVE PROBE. FAILURE TO FOLLOW THESE PRECAUTIONS 
CAN RESULT IN SERIOUS INJURY AND EQUIPMENT DAMAGE.
WARNINGWARNINGNEVER USE A PROBE THAT HAS FALLEN TO THE FLOOR. EVEN IF IT LOOKS OK, 
IT MAY BE DAMAGED.
CAUTIONAlways lower and center the Opertaor I/O Panel before moving the scanner.
CAUTIONThe LOGIQ™ 9 weighs 225 kg or more, depending on installed peripherals, (500 lbs., or more) 
when ready for use. Care must be used when moving it or replacing its parts. Failure to follow 
the precautions listed could result in injury, uncontrolled motion and costly damage.
ALWAYS:
Be sure the pathway is clear.
Use slow, careful motions.
Use two people when moving on inclines or lifting more than 16 kg (35 lbs).

1-8 Section 1-3 - Safety Considerations
1-3-3Mechanical Safety (cont’d)
NOTE: Special care should be taken when transporting the unit in a vehicle:
• Secure the unit in an upright position.
• Lock the wheels (brake)
• DO NOT use the Control Panel as an anchor point.
• Place the probes in their carrying case.
• Eject any Magneto Optical disk or CD from their drive. 
1-3-4 Electrical Safety
To minimize shock hazard, the equipment chassis must be connected to an electrical ground. The 
system is equipped with a three-conductor AC power cable. This must be plugged into an approved 
electrical outlet with safety ground. If an extension cord is used with the system, make sure that the total 
current rating of the system does not exceed the extension cord rating. 
The power outlet used for this equipment should not be shared with other types of equipment.
Both the system power cable and the power connector meet international electrical standards.
1-3-5 Labels Locations
Refer to the LOGIQ™ 9 Basic User Manual, Chapter 2, for the label locations.
CAUTIONKeep the heat venting holes on the monitor unobstructed to avoid overheating of the 
monitor.

1-3-6 Dangerous Procedure Warnings
Warnings, such as the examples below, precede potentially dangerous procedures throughout this 
manual. Instructions contained in the warnings must be followed.
1-3-7 Lockout/Tagout Requirements (For USA Only)
Follow OSHA Lockout/Tagout requirements by ensuring you are in total control of the electrical Mains 
plug.
1-3-8 Returning/Shipping Probes and Repair Parts
Equipment being returned must be clean and free of blood and other infectious substances.
GEMS policy states that body fluids must be properly removed from any part or equipment prior to 
shipment. GEMS employees, as well as customers, are responsible for ensuring that parts/equipment 
have been properly decontaminated prior to shipment. Under no circumstance should a part or 
equipment with visible body fluids be taken or shipped from a clinic or site (for example, body coils or 
an ultrasound probe).
The purpose of the regulation is to protect employees in the transportation industry, as well as the 
people who will receive or open this package.
NOTE: The US Department of Transportation (DOT) has ruled that “items that were saturated and/or 
dripping with human blood that are now caked with dried blood; or which were used or intended 
for use in patient care” are “regulated medical waste” for transportation purposes and must be 
transported as a hazardous material.
DANGERDANGEROUS VOLTAGES, CAPABLE OF CAUSING DEATH, ARE PRESENT 
IN THIS EQUIPMENT. USE EXTREME CAUTION WHEN HANDLING, TESTING 
AND ADJUSTING.
WARNINGWARNINGEXPLOSION WARNING
DO NOT OPERATE THE EQUIPMENT IN AN EXPLOSIVE ATMOSPHERE. 
OPERATION OF ANY ELECTRICAL EQUIPMENT IN SUCH AN ENVIRONMENT 
CONSTITUTES A DEFINITE SAFETY HAZARD.
WARNINGWARNINGDO NOT SUBSTITUTE PARTS OR MODIFY EQUIPMENT
BECAUSE OF THE DANGER OF INTRODUCING ADDITIONAL HAZARDS, DO NOT 
INSTALL SUBSTITUTE PARTS OR PERFORM ANY UNAUTHORIZED MODIFICATION 
OF THE EQUIPMENT.

1-10 Section 1-4 - EMC, EMI, and ESD
Section 1-4
EMC, EMI, and ESD
1-4-1 Electromagnetic Compatibility (EMC)
Electromagnetic compatibility describes a level of performance of a device within its electromagnetic 
environment. This environment consists of the device itself and its surroundings including other 
equipment, power sources and persons with which the device must interface. Inadequate compatibility 
results when a susceptible device fails to perform as intended due interference from its environment or 
when the device produces unacceptable levels of emission to its environment. This interference is often 
referred to as radio–frequency or electromagnetic interference (RFI/EMI) and can be radiated through 
space or conducted over interconnecting power of signal cables. In addition to electromagnetic energy, 
EMC also includes possible effects from electrical fields, magnetic fields, electrostatic discharge and 
disturbances in the electrical power supply.
1-4-2 CE Compliance
The LOGIQ™ 9 unit conforms to all applicable conducted and radiated emission limits and to immunity 
from electrostatic discharge, radiated and conducted RF fields, magnetic fields and power line transient 
requirements.
For applicable standards refer to the Safety Chapter in the Basic User Manual.
NOTE: For CE Compliance, it is critical that all covers, screws, shielding, gaskets, mesh, clamps, are in 
good condition, installed tightly without skew or stress. Proper installation following all 
comments noted in this service manual is required in order to achieve full EMC performance.
1-4-3 Electrostatic Discharge (ESD) Prevention
WARNINGWARNINGDO NOT TOUCH ANY BOARDS WITH INTEGRATED CIRCUITS PRIOR TO TAKING 
THE NECESSARY ESD PRECAUTIONS: 
1.ALWAYS CONNECT YOURSELF, VIA AN ARM-WRIST STRAP, TO THE ADVISED 
ESD CONNECTION POINT LOCATED ON THE REAR OF THE SCANNER (TO THE 
RIGHT OF THE POWER CONNECTOR). 
2.FOLLOW GENERAL GUIDELINES FOR HANDLING OF ELECTROSTATIC 
SENSITIVE EQUIPMENT.
