Using removable media
The following removable media can be used for data storage:
•  5 1/4” Magneto Optical disk (1.3, 5.4, 8.6 and 9.1 Gb)
•  CD-R (CD-RW is not supported)
Recommendation concerning CD-R 
handling
To avoid data loss, never touch the recordable surface of a CD-
R. Handle the disk only by the outer edge. Do not place it face 
down on a hard surface. Fingerprints or scratches will make the 
disk unusable. Before usage, verify that CD-R surface has no 
visible scratches. If there are any scratches, do NOT use the 
CD-R.
Formatting removable media
Removable media have to be formatted prior to use as 
described in ’Tools’ on page 435.
Ejecting removable media
Alternative: Press 
F3. Do not eject the 
CD using the but-
ton on the CD 
drive.
1. Press ALT+E to eject the disk.
The Eject device menu is displayed (Figure 2-5).
 Figure 2-5: The Eject device menu
2. Select the relevant media.
CAUTIONUse only 24x or higher CD-R.
CAUTIONAvoid using CD-R to store patient data. The CD-R can be used for 
storage of images for presentation purposes.

Recording images on VCR
VCR recording is started and stopped from the RECORD/PAUSE 
key on the control panel. The status of the VCR is indicated by 
a symbol on the Title bar (for detail about how to use VCR 
recorder, refer to ’VCR operation’ on page 384).

Zoom
The unit supports two types of zoom: the display zoom and the 
high resolution (HR) zoom.
•  The Display zoom magnifies the image display in both 
frozen and live 2D, M-Mode and combined modes.
•  The HR zoom concentrates the image processing to a user 
selectable portion of the image, resulting in an improved 
image quality and a higher frame rate in the chosen ROI.

To magnify an image (Display zoom)
The Display zoom is 
available in live and 
replay.1. Rotate the Zoom knob clockwise.
The resulting magnified image appears in the acquisition 
window while the un-magnified image is displayed in the 
control window showing the outlined zoom region.
2. Use the Trackball to position the zoom area over the 
desired portion of the image.
3. To turn off the Display zoom, rotate the Zoom knob counter 
clockwise.
To activate the HR zoom
As a default setting, 
the zoom area is 
centered to the cur-
sor/color area if 
present.1. Press ZOOM.
The resulting zoomed image appears in the acquisition 
window and a frozen reference image is displayed in the 
control window showing the outlined zoom region.
2. Use the Trackball to position the zoom area over the 
desired portion of the image.
3. Increase size as desired by turning the zoom knob 
clockwise.
4. Press 
ZOOM one more time to turn off the HR zoom.

Physiological traces
The physiological module consists of four channels: ECG/
Respiration, Phono, AUX 1 and AUX 2. The two channels 
AUX1 and AUX2 are both capable of handling external ECG 
signals from other diagnostic ECG devices. AUX2 is also 
capable of handling a pulse/pressure signal. The scanned 
image that is displayed is synchronized with the ECG, 
respiration and phono traces. In M-Mode or Doppler, the traces 
are synchronized to that particular modes sweep.
The operator can control the gain, the position and the sweep 
rate of the traces using the assignables on the control panel.

Connecting the ECG/Respiration
Over view
The ECG cable is a modular cable consisting of two different 
cables parts:
• The Trunk: a single cable connecting to the system at one 
end, and providing a cable splitter device at the other end 
(see Figure 2-8). 
• The triple color-coded electrode cable: to be inserted in 
the splitter device. Each electrode cable hooks up to the 
appropriate stick-on electrode by a color-coded clip type 
connector.
The color-coding of the electrodes follows one of two standards 
that are common in different parts of the world. The cable 
splitter device has a drawing defining the color codes, names 
and body location for the two standard color codes (see 
Figure 2-8).

To connect the internal ECG
1.Connect the ECG trunk cable into the rectangular-shaped 
socket marked ECG on the patient trace (I/O) panel. The 
patient trace (I/O) panel is located in the front left of the 
ultrasound unit (see Figure 2-7).
2.Hook up the electrode cables to the electrodes, following 
the appropriate convention (see Figure 2-8).
Connecting the Phono
Over view
The phono consists of a microphone with a cable and a 
connector.

To connect the Phono
1.Plug the connector into the socket marked Phono on 
Patient (I/O) panel (see Figure 2-7).
