1-3-11 How to remove the Ghost CD-ROM
The Ghost CD-ROM (Base System Software Load Image CD-ROM) is mounted on the PC-BOX inside 
the scanner using velcro tapes. The upper side of the PC-BOX cover contains sharp edge causing a FE 
to have possibility of cutting his hand if he removes the CD-ROM with the PC-BOX cover closed.

EMC, EMI, and ESD
1-4-1 Electromagnetic Compatibility
Electro Magnetic 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 interface from its environment or 
when the device produces unacceptable levels of mission to its environment. This interface is often 
referred to as radio-frequency or electromagnetic interface (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 Electrostatic Discharge (ESD) Prevention
1-4-3 CE Compliance
The LOGIQ™ 7 unit conforms to all applicable conducted and radiated emission limits and immunity 
from electrostatic discharge, radiated and conducted RF fields, magnetic fields and power line transient 
requirements.
Applicable standards are: 47CFR Part18, IEC60601-1-2, and 806-13.
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.
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 dedicated ground point located on the rear of the scanner (to the left of the power 
connector) or a proper frame ground.
2.) Follow general guide lined for handling of electrostatic sensitive 
equipment.

Overview
2-1-1 Purpose of this chapter 2
This chapter provides the information required to plan and prepare for the installation of a LOGIQ™ 7. 
Included are descriptions of the facility and electrical needs to be met by the purchaser of the unit. A 
checklist is also provided at the end of this section to help determine whether the proper planning and 
preparation is accomplished before the actual equipment installation is scheduled.

2-2-1-1 Cooling
The cooling requirement for the LOGIQ™ 7 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 diameters can be a source 
of EMI which could degrade image quality. These controls should be selected to minimize possible 
interface. Table 2-2   Environmental Requirements for LOGIQ™ 7 Scanners

2-2-2 Electrical Requirements
2-2-2-1 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 Line:
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. 
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.
2-2-2-2 LOGIQ™ 7 Power Requirements The following power line parameters should be monitored for one week before installation. We 
recommend that you use an analyzer Dranetz Model 606-3 or Dranetz Model 626:
2-2-2-3 Inrush Current Inrush Current is not a factor to consider due to the inrush current limiting properties of the power 
supplies.
2-2-2-4 Site Circuit Breaker It is recommended that the branch circuit breaker for the machine be ready accessible. Table 2-4   Electrical Specifications for LOGIQ™ 7
