CAUTION:
10. 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.
11. Do not turn OFF the power supply of the system during printing, data saving, or invoking. 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.
