No. 2B771-050EN*F S-4

WARNING: 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. • 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.

No. 2B771-050EN*F S-5

WARNING:

(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. 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. Handling the cord on this product will expose you to lead, a chemical known to the State of California to cause birth defects or other reproductive harm. Wash hands after handling. 18. This device is contraindicated for ophthalmic use or any application that causes the acoustic beam to pass through the eye. 19. 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.

No. 2B771-050EN*F S-8

CAUTION:

(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. If there is a limited amount of free space on the hard disk, the time required to display the ultrasound image after the system power is turned ON increases. 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. Standby mode (1) Before setting the system to Standby mode, be sure to save or print the necessary data. Otherwise, the data will be lost. (2) Do not set the system to Standby mode during printing, data saving, or invoking. Doing so may cause an error in these processes. (3) In addition, if the system is set to Standby mode during access to media, the media may be damaged. Furthermore, when used the next time, the printer or DVD/CD drive will not operate correctly. 12. Precautions regarding patient information entry (1) Be sure to register and save the patient ID before starting an examination for a new patient. If measurement is performed for a new patient for whom the patient ID is not registered or saved, the measurement results and other data cannot be saved in the system. In addition, the data for the two patients are mixed together, which may result in incorrect diagnosis. (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) 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. (4) Enter the patient information including LMP and IVF correctly in the patient ID registration screen. Otherwise, the fetal growth data will be calculated incorrectly. (5) Do not enter a patient ID consisting of spaces only. Doing so will result in reading/writing of data to/from media and DICOM transfer to other systems being performed incorrectly.

No. 2B771-050EN*F S-9

CAUTION: 13. Cautions regarding the presets (1) When a new imaging preset is to be created, the Exam Type is displayed automatically as the imaging preset name in the dialog. Be sure to change it. Otherwise, the examination may not be started with the factory setting even when "Factory" is selected in Exam Type registration in the system preset setting menu (refer to subsection 10.7). (2) If a change has been made to the system presets, be sure to turn OFF/ON the system power. Otherwise, the change will not go into effect. 14. 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. 15. Precautions regarding the measurements (1) For basic measurements, the measured data is lost when image freeze is released or the image mode is changed during measurement. (2) The measurement data is lost when the system is turned OFF. However, the measurement data saved for application measurements is not lost. (3) The basic measurement result is not displayed on the report. (4) On the application measurement result screen, some calculation results are displayed. To check all the measurement results (calculation results), perform checks on the report screen. (5) The results edited on the report screen are not reflected in the measurement results on the image display. (6) When measurement is to be performed in M-mode or Doppler mode, confirm that the entire screen has been refreshed after changing the mode or settings. Otherwise, measurement may not be performed correctly.

No. 2B771-050EN*F S-10

CAUTION: 16. 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. 17. Peripheral units (1) To prevent electric shock, do not connect the peripheral units (video printer, VCR, 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) Some printers cannot detect print errors. Use the actual printout to confirm whether the data is printed correctly. (3) Do not turn OFF the power to the printer during printing. This may result in system malfunction. (4) Do not turn the power to peripheral devices ON or OFF during the system startup or shutdown process. This may result in system malfunction. (5) When the system is in Standby mode, do not disconnect any peripheral unit or turn the power ON/OFF. A malfunction of the peripheral unit may result. (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. 18. When an attempt is made to archive images on media or transfer them with the DICOM protocol, the following dialog may be displayed. Sorry. DVD/CD and DICOM storage are not available now. Please store important images to hard disk. Please power off and then power on to make them available. In this case, archiving to media and DICOM transfer cannot be performed. Store the important images on the hard disk. If you wish to archive images on media or transfer them with the DICOM protocol immediately, reboot the system. 19.

No. 2B771-050EN*F S-11

CAUTION: 20. Frame missing error in recording with the Snapshot Clips function (1) If the system detects that 4 or more consecutive image frames are missing, the error message below is displayed and the images are not recorded. Release the freeze status and acquire the image again. "System busy. Failed in Storing the image." (2) If the system detects that less than 4 consecutive image frames are missing, the message below is displayed at the bottom of the monitor. In this case, the images are recorded. "System busy. Some frames were missing." 21. 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 operation panel, the pop up menu and the touch panel other than the ACOUSTIC POWER, the MI/TI value may change in a direction not intended for those switches. 22. If preventive maintenance is performed by the user, special care must be taken to ensure safety. 23. If any abnormality of the system is found as a result of inspection, stop using the system and contact your TOSHIBA representative for repair. 24. 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.
