For more information, contact your TOSHIBA representative. * Be sure to connect the potential-equalization lead wire before inserting the equipment power plug into the receptacle. Also, be sure to remove the equipment power plug from the receptacle before disconnecting the wire to avoid electrical shock. 3. Information concerning the functional earth terminal (
):
Use of the functional earth terminal as protective earth is not allowed. The system should be connected according to local requirements and should not conflict with IEC60601-1 requirements. 4. Connect the earth conductor only before turning ON the system. Disconnect the grounding cable only after turning OFF the system. Otherwise, electric shock may result. 5. Do not connect this system to outlets with the same circuit breakers and fuses that control current to devices such as lifesupport systems. If this system malfunctions and generates an overcurrent, or when there is an instantaneous current at power ON, the circuit breakers and fuses of the building's supply circuit may be tripped. 6. A separate power outlet of the specified rating must be provided to supply power to the diagnostic ultrasound system. Refer to the "Specifications" subsection for the power requirements of the diagnostic ultrasound system. Do not connect the diagnostic ultrasound system to the same power outlet as another device. Doing so may cause the power circuit breaker of the facility to trip, the fuses to blow, or a fire or electric shock to occur. 7. Do not push the system from the side. If the system is pushed from the side, it may fall down and cause injury. 8. When the optional reference signal 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 reference signal cable. • The reference signal cable must be connected correctly.
No. 2B771-022EN*A S-3
WARNING:
(2) Connect the reference signal 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 reference signal 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. 9. Before using equipment such as an electric scalpel, highfrequency therapy equipment, a defibrillator, etc., remove the ECG electrodes from the patient. In addition, do not allow ultrasound transducers or PCG microphones to come into contact with the patient. The patient may be burned or receive an electric shock. 10. 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. 11. Cautions regarding the biopsy procedures (1) To perform biopsy procedures while observing ultrasound images, a thorough understanding of ultrasound diagnosis and adequate training in biopsy procedures are required. Biopsy procedures are safer when performed using image observation than when performed without images. However, 100% safety and reliability cannot be assured even when performing biopsy procedures using image observation. If biopsy procedures are performed without proper knowledge or training, they may be performed incorrectly and cause various patient side effects. (2) In the situations listed below, the biopsy needle may fail to reach the target. Incorrect biopsy may cause various patient side effects. • A biopsy procedure is performed without adequate skills. • A biopsy adapter other than that specified is used. • The biopsy adapter is mounted at an incorrect position. • A biopsy needle that is unsuitable for the purpose of the biopsy is used.
No. 2B771-022EN*A S-4
WARNING:
• A biopsy needle that is unsuitable for the biopsy adapter is used. • The image is frozen but it goes unnoticed, and the biopsy procedure is continued. • The position of the biopsy needle end is misinterpreted on the image. (3) Before and after a biopsy procedure is performed, confirm that there are no abnormalities with the biopsy adapter. If an abnormal biopsy adapter is used, the patient may be injured. (4) During a biopsy procedure, the needle may deviate from the desired course due to the tissue characteristics or the type of needle. In particular, needles with small diameters may deviate to a greater degree. Always monitor the target region and the needle end while performing a biopsy procedure. (5) Sterilize the transducer and biopsy adapter before and after an ultrasound-guided biopsy procedure. Failure to do so may result in the transducer and adapter becoming a source of infection. (6) 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. (7) Do not freeze the image when performing a biopsy procedure. Biopsy procedures may be performed incorrectly on frozen images. (8) Confirm that the selected needle mark angle matches the angle indicated on the biopsy adapter to be used. (9) The biopsy target may shift due to unexpected patient motion when the biopsy needle is inserted, or else due to respiratory movement. Always monitor the target region and the needle tip while performing a biopsy procedure. 12. When a transducer is applied to a patient with a high body temperature, the rate of heat dissipation from the transducer may be lower than normal. Take care not to cause a burn during examination (especially during surgery or an intracavitary examination). If the surface temperature of the transducer becomes abnormally high, stop using the transducer and contact your service representative. 13. 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. 14. This system is provided with a lossy data compression function for images. Although this function helps reduce the size of stored images, it can cause image deterioration. The amount of compression, therefore, must be limited so that the image quality is maintained at a level which does not adversely affect image viewing.
No. 2B771-022EN*A S-5
WARNING: 15. For the safety precautions regarding the use of contrast medium etc. in CHI mode, refer to the operation manual, Application volume. 16. 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 turning the power OFF/ON and the examination may not be able to continue. 17. 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. 18. Do not use the controls, adjusters, or operating sections of the DVD/CD unit in a manner other than specified. Incorrect use may cause hazardous beams to be radiated.
CAUTION: 1. Precautions concerning clinical examination techniques (1) This operation manual is intended for users who are wellversed in the principles and basic techniques of ultrasound. (2) This system must be used only by medical personnel fully trained in clinical examination techniques. (3) 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, in the room where the system is installed. (2) If a user brings a device which generates radio waves near the system, they must be instructed to immediately turn OFF the device. This is necessary to ensure the proper operation of the system.
No. 2B771-022EN*A S-6
CAUTION: 3. Precautions concerning installation and movement of the system (1) Be sure to install the system on a level floor and lock the casters. If this is not done, the system may move, injuring the patient. (2) When the system is moved over a sloped surface, it must be moved by two persons. Otherwise, the system may slide unexpectedly and cause a serious injury. (3) Do not sit on the system. The system may move, causing you to lose your balance and fall. (4) Do not place any objects on top of the monitor. They may fall, causing injury. (5) Confirm that movable sections such as the LCD arm are locked before moving the system. Otherwise, the movable sections may move unexpectedly and cause 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 reference signal 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. In normal diagnostic ultrasound mode, there is no danger of a lowtemperature burn; however, keeping the transducer on the same region of the patient may cause such a burn. 5. 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. 6. Terminals and connectors on the system rear panel (1) Only the specified device must be connected to the USB connector or other connectors. Otherwise, smoke or an electric shock may result. (2) 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. (3) Turn OFF the system power before connecting or disconnecting the cable from the ETHERNET terminal. If the cable is connected or disconnected with the system power ON, the system may not operate properly. (4) When a HUB is used, turn ON the system power only after tuning ON the power to the HUB.

CAUTION: 7. Physio panel (option) (1) Only medical equipment that conforms with the IEC60601-1 standards must be connected to AUX. Otherwise, an electric shock may result. (2) When external signals are input to AUX of the Physio panel, the signal level that can be input is restricted. Contact your TOSHIBA representative for details. 8. 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. 9. Back up the stored data (image data and exam history) periodically and delete unnecessary data. 10. Do not turn OFF the power supply of the system during printing, data saving, or invoking. Doing so may result in failure of saving or printing or damage to the data. In addition, doing so during access to media may damage the media. 11. Entry of patient ID (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. Note that when the patient information is modified by pressing the F2 key, the patient information for the data already recorded in the image memory is also 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. (2) 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. (3) In systems in which the UIDM-590A is installed, confirm that "ADM Ready" is displayed at the bottom left of the screen after the power is turned ON, and then press the F2 key and enter the patient ID.
No. 2B771-022EN*A S-8
CAUTION: 12. Position of the biopsy target on the image and the biopsy needle Even though the biopsy target and the biopsy needle are identified on the image, a biopsy may not always be successful due to dispersion of the ultrasound beam. This is especially relevant when a biopsy procedure is to be performed for a tubule or a very small region. To avoid biopsy failure, follow the instructions below. (1) Do not rely solely on the echo of the needle end on the image. Pay careful attention to the target, which should shift slightly when the biopsy needle comes into contact with it. (2) Perform biopsy only after confirming the size of the target and the likelihood of biopsy success. 13. 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. 14. Do not display or print the data imported from other devices in this system. Such data may not be able to be displayed or printed correctly. 15. Peripheral units (1) To prevent electric shock, do not connect the peripheral units (printer, video recoding device, etc.) to an external outlet. Peripheral units should be connected to the service outlet of the system. For the connection procedures, contact your TOSHIBA representative. (2) Do not connect non-recommended peripheral devices to the service outlet as the power capacity may be exceeded and leakage current may increase. (3) Some printers cannot detect print errors. Use the actual printout to confirm whether the data is printed correctly. (4) Do not turn OFF the power to the printer during printing. This may result in system malfunction. (5) Do not turn the power to peripheral devices ON or OFF during the system startup or shutdown process. This may result in system malfunction. (6) When printing is executed, do not turn the system power OFF before all the images are printed. The data in the print queue may be lost. (7) When the color printer is to be used for printing, make sure that its power is ON. If printing is executed when the printer power is OFF, a system malfunction may result.
No. 2B771-022EN*A S-9
CAUTION: 16. 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. 17. 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 operating panel and the pop-up menu other than the ACOUSTIC POWER switch, and the MI/TI value may change in a direction not intended for these switches. 18. If preventive maintenance is performed by the user, special care must be taken to ensure safety. 19. If any abnormality of the system is found as a result of inspection, stop using the system and contact your TOSHIBA representative for repair. 20. In no event shall TOSHIBA be liable for problems, damage, or loss caused by inspection performed by personnel other than TOSHIBA service personnel or those designated by TOSHIBA. 21. This system uses Windows XP as the OS. Do not change the settings of the OS. 22. Problems that typically occur in personal computers may also occur in this system. Important data must be stored on external storage media. 23. Only software authorized by TOSHIBA should be installed in this system. Otherwise, system failure or malfunction may result. Contact your TOSHIBA representative for details.
