S-3
WARNING: 7. Do not allow this system or other equipment to come into contact
with the patient. If this system or other equipment is defective,
the patient may receive an electric shock.
8. Do not connect to the system transducers other than those
specified by TOSHIBA, to prevent accidents such as burns,
electrical shock, or fire.
9. Do not subject the transducers to knocks. Use of defective
transducers may cause an electric shock.
10. Do not remove the covers or panels of the system, or electric
shock may result.
11. Prolonged and repeated use of keyboards can result in hand or
arm nerve disorders in some individuals. Observe the local
institution work safety/health regulations on keyboard use.
12. When the optional ECG cable is used, the following measures are
required.
(1) To prevent electric shock, check the following items before
operation.
•There must be no abnormality of the ECG cable.
•The ECG cable must be connected correctly.
(2) Connect the ECG cable to the system before attaching the
ECG electrodes to the patient. After the electrodes are
attached to the patient, be careful not to allow them to come
into contact with ground or other electrically live parts. If
the ECG cable connector or an electrode comes into contact
with ground or other electrically live parts, the patient may
receive an electric shock.
(3) Do not place the ECG electrodes in direct contact with the
patient's heart. Cardiac arrest may occur.
* The ECG electrodes are of the BF type and are not
designed to be placed in direct contact with the heart.
(4) To reduce the risk of electric shock or burns, use only the
cable and patient leads supplied with the reference signal
unit .
(5) The ECG electrodes used should be commercially available
products provided by the customer.
(6) Before using equipment such as an electric scalpel, high-
frequency therapy equipment, an electro stimulator, or a
defibrillator, remove the ECG electrodes from the patient. In
addition, do not allow ultrasound transducers to come into
contact with the patient. The patient may be burned or
receive an electric shock.
13. The needle mark displayed on the ultrasound image does not
indicate the actual position of the biopsy needle. It should only
be used as a reference.

No. 2B730-973EN*D
S-4
WARNING: 14. Confirm that the selected needle mark angle matches the angle
indicated on the biopsy adapter to be used.
15. The use of transducers and cables other than those specified,
with the exception of transducers and cables sold by Toshiba
Medical Systems Corporation as replacement parts, may result in
increased emissions or reduced system performance.
16. When operating the CD-R drive, do not use the controls,
adjusters, or operating sections in a manner other than specified.
Incorrect use may cause hazardous beams to be radiated.
Laser beams emitted by the optical pickup are hazardous to
humans (eyes). Do not look into the CD-R drive.
17. Prepare a backup system when an urgent examination is to be
performed, for example during an operation or for an emergency
case. If a severe problem should occur with the system, the
normal operation of the system may not be recovered by
resetting the system and the examination may not be able to
continue.
18. Accessory equipment connected to the analogue and digital
interfaces must comply with the relevant IEC standards (e.g.
IEC60950 for data processing equipment). Furthermore all
configurations should comply with the standard IEC60601-1-1.
Anyone who connects additional equipment to the signal input
part or signal output part configures a medical system, and is
therefore responsible that the system complies with the
requirements of IEC60601-1-1.
If in doubt, contact your TOSHIBA representative.
19. Do not use this transducer to examine the eyeball. Also do not
use this transducer in examinations that may cause ultrasound
beams to pass through the eyeball.
CAUTION: 1. Precautions concerning clinical examination techniques
(1) This system must be used only by medical personnel fully
trained in clinical examination techniques.
(2) This operation manual does not describe clinical examination
techniques. Selection of the proper clinical examination
technique must be based on specialized training and clinical
experience.
2. Malfunctions due to radiowaves
(1) Use of radiowave-emitting devices in the proximity of this kind
of medical electronic system may interfere with its operation.
Do not bring or use devices which generate radio waves, such
as cellular telephones, transceivers, and radio controlled toys,

unexpectedly and cause a serious injury.
(4) Do not sit on the system.
The system may move, causing you to lose your balance and
fall.
(5) Do not place any objects on top of the monitor. They may fall,
causing injury.
(6) Confirm that the peripheral units are secured before moving the
system. Otherwise, the peripheral units may fall and cause
injury.
(7) If the ECG cable is connected, disconnect it before moving the
system. Otherwise, the cable may get caught in the casters or
someone may trip over the cable and injury may result.
(8) When the system is moved over a step, be careful not to allow
the system to fall. When holding the system at the bottom to
help move it over a step, take special care to prevent hand
injuries.
4. To prevent electric shock, do not connect the peripheral units (video
printer, VCR, etc.) to an external outlet (except for Deskjet series
printers). Peripheral units should be connected to the service outlet
of the system. For the connection procedures, contact your
TOSHIBA representative.
In addition, be sure to use the cable supplied with the system to
connect a Deskjet series printer. If a different cable is used, there is
a risk of electric shock.
5. Before cleaning the system, be sure to disconnect the power cable
from the outlet. If the system is defective, there is a risk of electric
shock.
6. Do not allow fluids such as water to contact the system or
peripheral devices. Electric shock may result.
7. Terminals and switches on the system rear panel
(1) Only equipment that conforms to the safety standards must be
connected to the ETHERNET terminal on the rear panel.
Otherwise, smoke or an electric shock may result.

No. 2B730-973EN*D
S-6
CAUTION: (2) Turn OFF the system power before connecting or
disconnecting the cable from the ETHERNET terminal. If the

the system may not operate properly.
(3) When a HUB is used, turn ON the system power only after
tuning ON the power to the HUB.
(4) Do not press the RESET switch when the system is operating
normally. Data loss or damage to the system may result.
8. In normal diagnostic ultrasound mode, there is no danger of a low-
temperature burn; however, keeping the transducer on the same
region of the patient may cause such a burn.
9. Clean the ECG cable regularly.
(1) Do not allow clips to wet. The ECG is not displayed correctly.
(2) Do not soak the connector in the water.
Wipe the connector with dry cloth only.
The water may enter the connector inside, possibly resulting in
failure.
(3) Do not use solvents (such as paint thinner, benzine, or alcohol)
for cleaning the ECG cable.
10. Cleaning the LCD monitor
(1) Do not hit or apply strong pressure to the LCD surface during
cleaning. Doing so may damage the monitor.
(2) Never use a stiff or hard cloth to clean the LCD monitor.
Doing so may damage the monitor cover or LCD surface.
(3) If stains on the LCD surface are difficult to remove, wipe it
gently with a soft cloth slightly moistened with water.
Detergents or chemical agents should not be used because
they may damage the monitor.
(4) Do not attempt to clean the LCD monitor with organic solvents
such as benzine, paint thinner, and alcohol or abrasive
cleaners.
Such agents may damage the monitor cover or LCD surface.
Also, do not use mild detergent to clean the LCD surface.
(5) Do not allow liquid droplets to remain on the LCD surface.
The droplets may cause small stains when they dry or may
enter the LCD surface, possibly resulting in failure.
11. If there is any possibility of secondary infection, cover the entire
system with a sterile cover. To obtain a sterile cover, contact your
TOSHIBA representative.

No. 2B730-973EN*D
S-7
CAUTION: 12. Precautions regarding patient information entry
(1) Before examining a new patient, press to delete the
patient information and data recorded in the image memory
for the previous patient. Otherwise, the new data may be
confused with the data of the previous patient.
(2) If the patient information is modified by pressing PATIENT
ID , the
patient information for the data already recorded in the image
memory is not modified (the data recorded in the image
memory is not deleted). Thus, if the data recorded in the
image memory is that for the previous patient, images for the
different patients will have the same patient information, and
this may cause confusion.
It a patient ID is to be changed, press to delete the
patient information and data recorded in the image memory
for the previous patient. Otherwise, the data belonging to the
current patient may be confused with the data for the previous
patient.
(3) Confirm that the patient to be examined is the same as the
patient ID. There is a possibility of recording images with
incorrect patient IDs.
(4) Enter the patient's height and weight correctly in the patient ID
registration screen. If the entered height and weight are not
correct, the BSA will be calculated incorrectly.
(5) Enter the patient information including LMP and IVF correctly
in the patient ID registration screen. Otherwise, the fetal
growth data will be calculated incorrectly.
13. Cine
When performing examination of a new patient, press to
delete the recorded data in the image memory. Otherwise, the new
data may be confused with the data of the previous patient.
14. The displayed reference signals should be used for reference only.
They should not be used for diagnosis or monitoring. In patients
with cardiac pacemakers, an implantable electro stimulator, or
arrhythmia, the heart rate or other parameters may not be
displayed correctly.
15. Operation of the CD-R drive
(1) Do not leave the tray open. Dust may enter the unit and cause
a malfunction, or a person may hit the tray and be injured.
Open the tray only when necessary.
(2) Be careful not to allow your fingers to be caught by the disk
tray when opening or closing the disk tray. They may be
injured.

No. 2B730-973EN*D
S-8
CAUTION: (3) Do not use lens cleaner to clean the disk. Lens cleaner will
damage the drive.
16. Acoustic power
(1) The FDA allows ultrasound equipment to output acoustic
power level TRACK3, which is higher than TRACK1, provided
that MI/TI values are displayed on the system. This means
that users have a higher degree of responsibility for safety
than manufacturers. Against this background, users are
required to understand the ultrasound bioeffects and their
causes.
(2) It is strictly required that acoustic output be set based on the
ALARA (As Low As Reasonably Achievable) principle.
However, not all examinations can be performed with an
extremely low level of acoustic energy. Controlling the
acoustic level at an extremely low level leads to low-quality
images or insufficient Doppler signals, adversely affecting the
reliability of the diagnosis. However, increasing the acoustic
power more than necessary does not always contribute to an
increase in quality of information required for diagnosis,
rather increasing the risk of generating bioeffects.
Users must take responsibility for the safety of patients and
utilize ultrasound deliberately. Deliberate use of ultrasound
means that output power of ultrasound must be selected
based on ALARA.
(3) Set the ultrasound output as low as possible when a fetus is
to be exposed to ultrasound.
(4) Note that there are switches on the main panel and menu
other than the ACOUSTIC POWER, the MI/TI value may change
in a direction not intended for those switches.
17. Do not turn OFF the power supply of the system during printing,
data saving, or data access. Doing so may cause these processes
to not operate correctly. In addition, doing so during access to a
CD-R or an HDD may damage these media.
18. Measurements
(1) The measured data is lost when image freeze is released
during measurement. (In the case of application
measurements, the data loss depends on the preset settings.)
(2) The measured data is lost when the system is turned OFF or
is pressed.
19. Do not rub the LCD surface with a hard material or apply strong
pressure to the LCD surface. Doing so may cause scratches on
the LCD surface or result in damage to the monitor.

No. 2B730-973EN*D
S-9
CAUTION: 20. Main panel switch configuration
(1) The switch configuration on the main panel of this system can
be changed. The switch settings may therefore differ
depending on the system. Confirm the switch configuration
of your system before use.
For details, refer to subsection 3.2 "Main Panel".
(2) The descriptions in this operation manual are based on the
standard switch configuration. If the switch configuration has
been changed, the differences between the current
configuration and the standard configuration must be
understood before use.
(3) Do not press two or more switches on the main panel
simultaneously. System malfunction may result.
21. When discarding any part of this system, follow all applicable local
regulations.
22. When this system is used to examine an elderly patient or an
infant, an attendant should be present as required.
CAUTION: 1. Do not use this system in locations subject to intense electric or magnetic fields
(near transformers, for example). In such locations, the monitor will be
adversely affected.
2. Do not use this system near devices generating high frequencies (such as
medical telemeters and cordless telephones). The system can malfunction or
adversely affect such devices.
3. Confirm that a core for preventing EMC problems is attached to the transducer
cable. If a core is not attached, the system may affect other equipment.
Contact your service representative for details.
4. To prevent damage to the system, do not use it in:
•Locations where it may be exposed to direct sunlight
•Locations where it may be subject to sudden changes in temperature
•Locations that are dusty
•Locations where it may be subjected to vibrations
•Locations near heat generators
•Locations where the humidity may be high
•Locations where the air filter of the system is blocked (for example, near a
wall or another unit)
5. Turn ON the system only after the power has been OFF for more than 30
seconds. If the system is turned ON immediately after being turned OFF, it may
malfunction (for example, the time display may not be updated). If there is a
malfunction, turn OFF the power supply of the system, wait at least 30 seconds,
and turn it ON again.
6. Power ON/OFF
(1) Make sure that no recording media is present in the corresponding drives
before the system power is turned ON. Otherwise, the media may be
damaged or a malfunction may result.
