General Console Requirements
2-2-1 Console Environmental Requirements
2-2-1-1 Cooling
The cooling requirement for the LOGIQ™ 9 is 3500 BTU/hr. This figure does not include cooling needed 
for lights, people, or other equipment in the room. Each person in the room places an additional 300 
BTU/hr. demand on the cooling system.
2-2-1-2 Lighting
Bright light is needed for system installation, updates and repairs. However, operator and patient 
comfort may be optimized if the room light is subdued and indirect. Therefore a combination lighting 
system (dim/bright) is recommended. Keep in mind that lighting controls and dimmers can be a source 
of EMI which could degrade image quality. These controls should be selected to minimize possible 
interference.
2-2-2 Electrical Requirements
NOTE: GE Medical Systems requires a dedicated power and ground for the proper operation of its 
Ultrasound equipment. This dedicated power shall originate at the last distribution panel before 
the system.
Sites with a mains power system with defined Neutral and Live:
The dedicated line shall consist of one phase, a neutral (not shared with any other circuit), and a full 
size ground wire from the distribution panel to the Ultrasound outlet.
Sites with a mains power system without a defined Neutral:
The dedicated line shall consist of one phase (two lines), not shared with any other circuit, and a full 
size ground wire from the distribution panel to the Ultrasound outlet.
NOTE: Please note that image artifacts can occur, if at any time within the facility, the ground from the 
main facilitys incoming power source to the Ultrasound unit is only a conduit.

2-4 Section 2-2 - General Console Requirements
2-2-3 EMI Limitations
Ultrasound machines are susceptible to Electromagnetic Interference (EMI) from radio frequencies, 
magnetic fields, and transients in the air or wiring. Ultrasound machines also generate EMI. The 
LOGIQ™ 9 complies with limits as stated on the EMC label. However, there is no guarantee that 
interference will not occur in a particular installation.
Possible EMI sources should be identified before the unit is installed. 
Electrical and electronic equipment may produce EMI unintentionally as the result of a defect. These 
sources include: 
• medical lasers, 
• scanners, 
• cauterizing guns, 
• computers, 
•monitors, 
•fans, 
• gel warmers, 
• microwave ovens,
• light dimmers 
• portable phones. 
The presence of a broadcast station or broadcast van may also cause interference.
See Table 2-4 for EMI Prevention tips.
Table 2-4    EMI Prevention/Abatement
EMI RuleDetails
Be aware of RF sourcesKeep the unit at least 5 meters or 15 feet away from other EMI sources. Special shielding may be 
required to eliminate interference problems caused by high frequency, high powered radio or video 
broadcast signals.
Ground the unitPoor grounding is the most likely reason a unit will have noisy images. Check grounding of the 
power cord and power outlet.
Replace all screws, RF 
gaskets, covers, coresAfter you finish repairing or updating the system, replace all covers and tighten all screws. Any 
cable with an external connection requires a magnet wrap at each end. Install the shield over the 
front of card cage. Loose or missing covers or RF gaskets allow radio frequencies to interfere with 
the ultrasound signals.
Replace broken RF gasketsIf more than 20% or a pair of the fingers on an RF gasket are broken, replace the gasket. Do not 
turn on the unit until any loose metallic part is removed.
Do not place labels where 
RF gaskets touch metalNever place a label where RF gaskets meet the unit. Otherwise, the gap created will permit RF 
leakage. Or, if a label has been found in such a position, move the label.
Use GE specified harnesses 
and peripheralsThe interconnect cables are grounded and require ferrite beads and other shielding. Also, cable 
length, material, and routing are all important; do not change from what is specified.
Take care with cellular 
phonesCellular phones may transmit a 5 V/m signal; that could cause image artifacts. 
Properly dress peripheral 
cablesDo not allow cables to lie across the top of the card cage or hang out of the peripheral bays. Loop 
the excess length for peripheral cables inside the peripheral bays. Attach the monitor cables to the 
frame.

Facility Needs
2-3-1 Purchaser Responsibilities
The work and materials needed to prepare the site is the responsibility of the purchaser. Delay, 
confusion, and waste of manpower can be avoided by completing pre installation work before delivery. 
Use the Pre installation checklist to verify that all needed steps have been taken. Purchaser 
responsibility includes:
• Procuring the materials required.
• Completing the preparations before delivery of the ultrasound system.
• Paying the costs for any alterations and modifications not specifically provided in the sales contract.
NOTE: All electrical installations that are preliminary to the positioning of the equipment at the site prepared for 
the equipment must be performed by licensed electrical contractors. Other connections between pieces 
of electrical equipment, calibrations, and testing must also be performed by qualified personnel. The 
products involved (and the accompanying electrical installations) are highly sophisticated and special 
engineering competence is required. All electrical work on these products must comply with the 
requirements of applicable electrical codes. The purchaser of GE equipment must only utilize qualified 
personnel to perform electrical servicing on the equipment. 
The desire to use a non–listed or customer provided product or to place an approved product further 
from the system than the interface kit allows presents challenges to the installation team. To avoid 
delays during installation, such variances should be made known to the individuals or group performing 
the installation at the earliest possible date (preferably prior to the purchase).
The ultrasound suite must be clean prior to delivery of the machine. Carpet is not recommended 
because it collects dust and creates static. Potential sources of EMI (electromagnetic interference) 
should also be investigated before delivery. Dirt, static, and EMI can negatively impact system reliability.

2-3-5 Networking Pre-installation Requirements
2-3-5-1 Purpose of the DICOM Network Function
DICOM services provide the operator with clinically useful features for moving images and patient 
information over a hospital network. Examples of DICOM services include the transfer of images to 
workstations for viewing or transferring images to remote printers. As an added benefit, transferring 
images in this manner frees up the on-board monitor and peripherals, enabling viewing to be done while 
scanning continues. With DICOM, images can be archived, stored, and retrieved faster, easier, and at 
a lower cost.
2-3-5-2 DICOM Option Pre-installation Requirements
To configure the LOGIQ™ 9 to work with other network connections, the site’s network administrator 
must provide some necessary information.
Information must include: 
• A host name, local port number, AE Title, IP address and Net Mask for the LOGIQ™ 9. 
• The IP addresses for the default gateway and other routers at the site for ROUTING 
INFORMATION.
• The host name, IP address, port and AE Title for each device the site wants connected to the 
LOGIQ™ 9 for DICOM APPLICATION INFORMATION. A field for the make (manufacturer) and 
the revision of the device, is also included. This information may be useful for solving errors.
