Acceptable Devices
The Patient Environmental devices shown on the previous page 
are specified to be suitable for use within the PATIENT 
ENVIRONMENT.
Unapproved Devices
Accessories, Options, Supplies 
CAUTIONDO NOT connect any probes or accessories without approval 
by GE within the PATIENT ENVIRONMENT.
See ‘Peripheral Update for EC countries’ on page 4-23 for 
more information.
CAUTIONDO NOT use unapproved devices. 
If devices are connected without the approval of GE, the 
warranty will be INVALID.
Any device connected to the LOGIQ E9 must conform to one or 
more of the requirements listed below:
1.  IEC standard or equivalent standards appropriate to 
devices.
2.  The devices shall be connected to PROTECTIVE EARTH 
(GROUND).
CAUTIONUnsafe operation or malfunction may result. Use only the 
accessories, options and supplies approved or recommended 
in these instructions for use.

Acoustic Output
Located on the upper right section of the system display monitor, 
the acoustic output display provides the operator with real-time 
indication of acoustic levels being generated by the system. See 
the Acoustic Output chapter in the Advanced Reference Manual 
for more information. This display is based on NEMA/AIUM 
Standards for Real-time Display of Thermal and Mechanic 
Acoustic Output Indices on Diagnostic Ultrasound Equipment.
Acoustic Output Display Specifications
The display consists of three parts: Thermal Index (TI), 
Mechanical Index (MI), and a relative Acoustic Output (AO) 
value. Although not part of the NEMA/AIUM standard, the AO 
value informs the user of where the system is operating within 
the range of available output. 
The TI and MI are displayed at all times. The TI display starts at 
a value of 0.0 and increments in steps of 0.1 The MI display 
values between 0 and 0.4 increment in steps of 0.01 and for 
values greater than 0.4, increments in steps of 0.1. 
Thermal IndexDepending on the examination and type of tissue involved, the 
TI parameter will be one of three types:
• Soft Tissue Thermal Index (TIS). Used when imaging soft 
tissue only, it provides an estimate of potential temperature 
increase in soft tissue.
• Bone Thermal Index (TIB). Used when bone is near the 
focus of the image as in the third trimester OB examination, 
it provides an estimate of potential temperature increase in 
the bone or adjacent soft tissue.
• Cranial Bone Thermal Index (TIC). Used when bone is 
near the skin surface as in transcranial examination, it 
provides an estimate of potential temperature increase in 
the bone or adjacent soft tissue.

Acoustic Output Display Specifications (continued)
Mechanical IndexMI recognizes the importance of non-thermal processes, 
cavitation in particular, and the Index is an attempt to indicate 
the probability that they might occur within the tissue.
Changing the
Thermal Index
Ty p eYou can select the displayed TI type on Utility -> Imaging ->  B-
Mode. This preset is application dependent so each application 
could specify a different TI type.
Display precision is ±0.1 and accuracy is ±50%. Accuracy of the 
power output displayed value on the Touch Panel is ±10%.
Controls Affecting Acoustic Output
The potential for producing mechanical bioeffects (MI) or 
thermal bioeffects (TI) can be influenced by certain controls. 
Direct. The Acoustic Output control has the most significant 
effect on Acoustic Output. 
Indirect. Indirect effects may occur when adjusting controls. 
Controls that can influence MI and TI are detailed under the 
Bioeffects portion of each control in the Optimizing the Image 
chapter. 
Always observe the Acoustic Output display for possible effects.

Best practices while scanning
NOTE:  Refer to the sections in Chapter 5 for a complete discussion of 
each control. 
Acoustic Output Default Levels
In order to assure that an exam does not start at a high output 
level, the LOGIQ E9 initiates scanning at a reduced default 
output level. This reduced level is preset programmable and 
depends upon the exam category and probe selected. It takes 
effect when the system is powered on or New Patient is 
selected.
To modify acoustic output, adjust the Power Output level on the 
Touch Panel.
HINTSRaise the Acoustic Output only after attempting image 
optimization with controls that have no effect on Acoustic 
Output, such as Gain and TGC. 
WARNINGBe sure to have read and understood control explanations for 
each mode used before attempting to adjust the Acoustic 
Output control or any control that can effect Acoustic Output. 
Acoustic
Output
HazardUse the minimum necessary acoustic output to get the best 
diagnostic image or measurement during an examination. 
Begin the exam with the probe that provides an optimum focal 
depth and penetration.

1.  Possible shock hazard. Do not remove covers 
or panels. No user serviceable parts are inside. 
Refer servicing to qualified service personnel.
2.  Signal ground point label CAUTION: This is 
only for “FUNCTIONAL GROUNDING”, NOT 
“PROTECTIVE EARTH”.
3.  Prescription Device (For U.S.A. Only)
4.  The equipment weighs approximately 135 kg 
(298 lbs). To avoid possible injury and 
equipment damage when transporting from one 
area of use to another:
• Be sure the pathway is clear.
• Limit movement to a slow careful walk.
• Use two or more persons to move the 
equipment on inclines or long distance.

8.  The CE Mark of Conformity indicates this 
equipment conforms with the Council Directive 
93/42/EEC.
9.  ETL Label: NRTL Listing and Certification Mark 
is used to designate conformance to nationally 
recognized product safety standards. The Mark 
bears the name and/or logo of the testing 
laboratory, product category, safety standard to 
which conformity is assessed, and a control 
number.
10.  Mercury Warning Label
[Not shown on the illustration]Grounding reliability
