GE HEALTHCARE DIRECTION 2286865, REVISION 14LOGIQ™ 7 SERVICE MANUAL Section 2-2 - General Console Requirements 2-5 2-2-3 EMI Limitations Ultrasound machines are susceptible to Electromagnetic Interference (EMI) from radio frequencies, magnetic fields, and transient in the air wiring. They also generate EMI. The LOGIQ™ 7 complies with limits as stated on the EMC label. However there is no guarantee that interface 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 defect. These sources include: • medical lasers, • scanners, • cauterizing guns, •computers, •monitors, •fans, • gel warmers, • microwave ovens, • light dimmers, • portable phones. The presence of broadcast station or broadcast van may also cause interference. See for EMI Prevention tips. Table 2-5 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 unit Poor 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, cores After you finish repairing or updating the system, replace all covers and tighten all screws. Any cable with an external connecti on 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 interface with the ultrasound signals. Replace broken RF gasketsIf more than 20% or a pair of fingers on the RF gaskets are broken, replace the gaskets. 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 r equire 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 phones Cellular phones may transmit a 5 V/m signal; that could cause image artifacts. Properly dress peripheral cables Do 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.

GE HEALTHCARE DIRECTION 2286865, REVISION 14LOGIQ™ 7 SERVICE MANUAL Section 2-3 - Facility Needs 2-7 Section 2-3 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. User the Pre Installation checklist to verify that all needed steps have been taken, Purchaser reasonability includes: • Procuring the materials required. • Completing the preparations before delivery of the ultrasound system. • Paying the costs for any alternations and modifications not specifically provided in the sales contract. NOTE: All electrical installation 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, products involved (and the accompanying electrical installations) are highly sophisticated and special engineering competence is required. All electrical work on these product 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 (preferable prior to purchase). The ultrasound suite must be clean proof 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.

GE HEALTHCARE DIRECTION 2286865, REVISION 14LOGIQ™ 7 SERVICE MANUAL 2-10Section 2-3 - Facility Needs 2-3-5 Networking Pre-installation Requirements 2-3-5-1 Purpose of 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™ 7 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™ 7. • 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™ 7 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.

GE HEALTHCARE DIRECTION 2286865, REVISION 14LOGIQ™ 7 SERVICE MANUAL 3-2Section 3-1 - Overview 3-1-3 Installation Warnings 1.) Since the LOGIQ™ 7 weighs approximately 225 kg. (496 lb) without options, preferably two people should unpack it. Two people are also preferable for installing any additional bulky items. 2.) There are no operator serviceable components. To prevent shock, do not remove any covers or panels. Should problems or malfunctions occur, unplug the power cord. Only qualified service personnel should carry out servicing and troubleshooting. 3.) After being transported, the unit may be very cold or hot. If this is the case, allow the unit to acclimate before you turn it on. It requires one hour for each 2.5×C increment its temperature is below 10×C or above 40×C. 3-1-3-1 Brake Pedal Operation CAUTIONEquipment damage possibility. Turning the system on without acclimation after arriving at site may cause the system to be damaged.
