Front End Parts Replacement 
The term front end as whole refers to the input and signal processing 
side of the system including probes, signal relays, ADC/DAC  
Vivid E9 Front End Processor (FEP) 
To prepare: 
 Power down the Vivid E9 
 Disconnect all probes and external I/O cabling. 
 Remove the Right Side Cover 
First remove the FEP cover. An EMI cover is used to ground the PCIe 
(GFI) cable to the FEP cover: 
Unscrew the fixing screw for the cover for the PCIe (GFI) cable and 
remove the cover for the PCIe cable. Shown on the left. Unplug the 
PCIe cable and unscrew the FEP Cover’s ten fixing screws.

Use top and bottom ejectors on GRLY board to slightly pull out front 
planes. 
Use last GTX board and repeat same process as GRLY. 
The card connectors have 
color-keys to prevent 
installation in an incorrect 
rack position. If the 
system is powered on with 
a card placed in the wrong 
position, the VIVID E9 will 
be destroyed.

Repeat those steps until the two XD_Bus boards release from 
remaining FEP boards. 
Gently release each of XD_Bus boards from connectors on GRLY and 
GTX. 
Be sure to place boards on 
ESD safe surface.

Module 9 System Adjustments 
This module covers adjustments that can be made to the GE E9 
systems.

The Touch Screen Calibration is found on the Operator Panel Test 
Dialog. Follow these steps to open the Operator Panel Test Dialog: 
 Select Config (F2). 
 Log on as ADM and select System > Test. 
 Select Operator Panel Test. This will open the Operator Panel 
Test Dialog:

 Select Calibrate. The Touch screen goes blank and display a cross 
in the screen’s upper left corner. 
 Put your finger on the centre of the cross and press slightly. This 
calibrates this point and the cross moves to the next point on the 
screen. Continue until all five points on the screen have been 
calibrated. 
 Select Done.to complete the calibration. 
DC Offset Calibration 
This procedure calibrates each ADC channel of the GRX inputs. The 
system calibrates the ADC to zero output when there is no signal on 
the input. These bias voltages are stored in the BEP. 
When to do a DC Offset Calibration 
You will need to do a DC Offset Calibration when: 
 Installing a new E9 system. 
 System software has been updated or replaced. 
 DRX board(s) or a MRX board has been interchanged. 
 A DRX board(s) or a MRX board has been replaced. 
 The Back End Processor has been replaced. 
DC Calibration Procedure 
 Disconnect all connected probes. 
 Power on the E9.

Operator Panel Adjustments 
This section covers adjustments to the operator panel XYZ 
mechanisms.  
Using the Park Lock Properly 
Before performing any adjustments or replacements it is important to 
be sure the user understands the following if they are experiencing 
problems with the XY park lock function. You should make sure they 
know they should: 
 Apply the brakes. The locking mechanism does not engage if the 
device can move when trying to park the console. 
 Push the release button and gently guide the console into the 
locked position until the lock is engaged. 
 They should not lean on or apply any weight on the console. If 
the console is not in the normal resting position, the lock will not 
engage when trying to park it.

Normal Operator Panel XY Movement 
When the Operator Panel is in the locked position if you press the left 
button (lock) of the Frogleg Controls, it will cause the motorized park 
lock to release and momentarily releases the brakes in the froglegs 
permitting the OP to move in the XY direction. 
When the console is not locked (floating) the lock button will only 
release the brakes in the froglegs to allow easy movement. 
The lock button must be pushed to move the OP into the locked 
position. 
When the lock button is pressed and the console is pushed back into 
the locked position, the U-bolt mechanically engages with the park 
lock. Pushing the lock button only releases the brakes, to allow the OP 
to be moved easily into the park lock. 
The user can proceed to park the Operator Panel or to leave it un-
parked. 
Notice that ONCE the user selects shutdown in the Monitor, the two 
buttons (Z-motion and XY-motion) are disabled. The brakes on the XY 
mechanism are released the XY movement is free but the Z-motion is 
disabled. If the user wants to adjust the Z mechanism after shutdown, 
they will need to use the handle in the back of the unit. 
 
 Logiq E9 Lock & 
Positioning Buttons 
Once the OP is in the lock 
position as the lock button 
is released, you will hear 
the sound of the park lock 
rotating to engage the U-
bolt. 
For R4, at shutdown, a 
message appears that 
tells the user that the 
Operator Panel is not 
parked. 
1.) U-bolt 
2.) Brakes (one inside each 
of the four XY arms) 
3.) Park Lock (engages U-
bolt)

XY Brake Adjustment 
Locate the hex adjustment screw behind the XY Assembly. Use a 3 
mm hex tool to adjust the XY Lock release for optimal lock and 
minimal slack in transport mode. 
 Clockwise will tighten the lock and will reduce slack, but will also 
require more force for engaging the lock. 
 Rotating counterclockwise will increase the slack. 
Too tight will reduce the slack and make it harder to engage the lock. 
Make the adjustments in 1/4 turn increments and test the lock until 
the optimum adjustment is achieved. 
Release the Park Lock Manually 
Follow this procedure if the park lock mechanism is not working, or 
the lock does not respond when pressing the Frogleg Controls: 
At the rear of the system, release the console’s frogleg mechanism by 
inserting a small tipped screwdriver into the release point. Press in 
until a click or the release, releases. 
 
 
 
 
Some force may be 
required if the lock 
adjustment is too tight.

Doppler effect – Change in the frequency of a periodic event 
(such as sound waves) due to a change in distance between the 
source and the observer. 
Doppler Range Gating – Range gate circuit only allows Doppler 
shift data from a user specified area to be displayed as output. 
Dynamic Host Configuration Protocol – A standardized 
network protocol used on IP networks for dynamically 
distributing network configuration parameters. IP addresses 
and networking parameters are requested automatically from 
a DHCP server, reducing the need to configure these settings 
manually. 
Electromagnetic Interference – (EMI) is when a radio 
frequency (RF) transmitting device interferes with the 
operation of another electronic device. In a healthcare 
environment wireless EMI can cause medical equipment to 
malfunction.

Ultrasound echoes are mapped to a gray scale display by 
intensity. Is derived from a stationary beam.

information about a performed study, the number of images 
that were scanned and the status of the exam. The information 
is shared between a digital modality and the PACS and RIS. 
Multiplexing – Multiple signals transmitted over a single 
medium. 
Picture Archive and Communications Systems – DICOM 
Medical imaging storage server that stores images from 
diagnostic devices such as MRI, ultrasound and X-rays.
