4-3-4 System B/M-Mode Checks
For a basic functional check of the system’s different modes, the Quick Guide will familiarize you with 
image optimization for B-Mode, M-Mode, Color Flow, and Doppler.
Figure 4-8  
Table 4-3    B/M-Mode Functions
Power Output (Acoustic Power)Optimizes image quality and allows user to reduce beam 
intensity. 10% increments between 0-100%. Values greater 
than 0.1 are displayed
Dynamic RangeDynamic Range controls how echo intensities are converted to 
shades of gray, thereby increasing the adjustable range of 
contrast.
Focus Number and PositionIncreases the number of transmit focal zones or moves the 
focal zone(s) so that you can tighten up the beam for a specific 
area. A graphic caret corresponding to the focal zone 
position(s) appears on the right edge of the image. 
Rejection
Selects a level below which echoes will not be amplified (an 
echo must have a certain minimum amplitude before it will be 
processed). 
Edge Enhance
Edge Enhance brings out subtle tissue differences and 
boundaries by enhancing the gray scale differences 
corresponding to the edges of structures. Adjustments to M 
Modes edge enhancement affects the M Mode only.
Frame AverageTemporal filter that averages frames together. This has the 
effect of presenting a smoother, softer image.
ColorizeEnables gray scale image colorization. To deactivate, reselect 
a Gray Map. 
Gray MapDetermines how the echo intensity levels received are 
presented as shades of gray.
Rotation  (Up/Down) Rotates the image by selecting the value from the pop up menu.
Frequency
Multi Frequency mode lets you 
downshift to the probes next lower
frequency or shift up to a higher 
frequency.

4-3-5 System CFM and PWD Checks 
Frame Rate/ResolutionOptimizes B Mode frame rate or spatial resolution for the best 
possible image.
B FlowProvides intuitive representation of non-quantitative 
hemodynamics in vascular structures.
Sensitivity/PRI Adjusts the sample rate for the flow signal. 
Background On/OffBackground On lets you view the anatomy roadmap; 
Background Off lets you view just flow information.
Sweep Speed Changes the speed at which the timeline is swept.
Figure 4-9  CFM and PWD Functions
Table 4-4    CFM and PWD Functions
BaselineAdjusts the baseline to accommodate faster or slower blood 
flows to eliminate aliasing.
PRF/Wall FilterVelocity scale determines pulse repetition frequency. If the 
sample volume gate range exceeds single gate PRF capability, 
the system automatically switches to high PRF mode. Multiple 
gates appear, and HPRF is indicated on the display.
Angle CorrectEstimates the flow velocity in a direction at an angle to the 
Doppler vector by computing the angle between the Doppler 
vector and the flow to be measured
ThresholdThreshold assigns the gray scale level at which color 
information stops. 
MapAllows a specific color map to be selected. After a selection has 
been made, the color bar displays the resultant map. 
InvertAllows blood flow to be viewed from a different perspective, i.e. 
red away (negative velocities) and blue toward (positive 
velocities). The real-time or frozen image can be inverted.

4-14 Section 4-3 - General Procedure
4-3-10 Using the MOD (Magneto-Optical Drive)
The 3.5 inch Magneto-Optical disk drive supports the following densities:
Standard: 640MB; 540MB; 230MB; and 128MB
Overwrite: 640MB; and 540MB
1.) Before installing an MO disk in the MOD, check the MO disk for loose hardware or damaged labels 
which could jam inside the MOD. Also, ensure that the slide switch in one corner of the disk is set 
so that the disk is write enabled (disk hole closed).
2.) Insert the disk into the MOD with the label facing up.
3.) There are different methods to eject a disk from the MOD. In some cases disk ejection is automatic. 
Manual ejection methods are listed below in preferred order from best (1) to worst (4).
a.) When in Archive Menu, use the softkey choice –or– click Image Presets up, then click the left 
softkey switch up for ARCHIVE
, then toggle the switch under EJECT MOD.
b.) Press the EJECT
 switch on the MOD while system is ON.
c.) Press and hold the EJECT
 switch while the system is booting.
d.) Mechanical ejection. Insert the end of a paper clip into the hole next to the EJECT
 switch while 
system power is OFF.Figure 4-10   Magneto-Optical Drive
NOTICENever move the unit with a disk in the MOD because the drive actuator will not be locked and 
the MOD could break. 
NOTICEAvoid mechanical ejection whenever possible. Mechanical ejection leaves the actuator 
unlocked and the MOD susceptible to damage if moved. If forced to use this method, reboot the 
system, then insert and eject a known good disk using one of the other manual ejection 
methods.
