Treatment at the time of the discovery of abnormality

1-3-1. Safety security of patient In use, watch it so that the instrument and the patient do not have any abnormality. If any abnormality occurred while the use of the instrument, the probe shall be removed from the patient promptly, and cancel the use. When the patient is abnormal, do appropriate medical treatments.

1-3-2. Instrumental treatment When an abnormality occurred to the instrument, refer to the 14. 'What to do in this case' of the Safety operation manual and do appropriate treatments. When any abnormality that is not described in the Safety operation manual occurred, the use is canceled, and a sign indicating the trouble shall be displayed or an appropriate sign shall be attached to the instrument, and contact our office listed in the back cover of the manual.

Operating the various switches Operating instructions of each switch are explained below.

1-4-1. + This switch is used to activate the measurement function which are assigned to the switches.

<Operation method> (1)

Press the →

switch.

Activates the measurement cursor and measurement function.

Measure according to the measurement procedure.

For details, refer to the Measurement manual.

1-4-2. CANCEL Used to terminate a selected operation or return to the previous step during a measurement.

1-4-3. CURSOR The CURSOR function moves or sets the cursor and the baseline of the Doppler pattern.

<CURSOR> <Operation method> (1)

Press the M switch to change over from the 1B mode display to the B/M mode display. →

(2)

The CURSOR switch is lighted in orange, and the cursor is displayed on the B mode image.

Using the trackball, move the cursor to the position where you wish to detect the M mode.

[Remark] The method of operating the cursor in the B/D mode is the same as the description above.

MN1-5481 Rev.2

The cursor cannot be moved when the B/M(B/D) image is frozen.

<BASE LINE SHIFT> By shifting the baseline, the Doppler pattern can be displayed without the aliasing. (1)

Press the PW switch to change over from the 1B mode display to the B/D mode display. →

The CURSOR switch is lighted in orange, and a cursor is displayed on the B mode image.

(2)

Adjust the position of the baseline with rotary encoder 4.

(3)

Press the CURSOR switch. →

(4)

The baseline is reset at the center position.

Press the CURSOR switch again. →

This function is finished.

1-4-4. DEPTH/RANGE The DEPTH/RANGE function switches over the display depth of the image. The display depth is switched over based on the transmission point of the displayed image. The depth is common to both the B and M mode images. The display depth that was last set remains, even if the mode changes. You cannot change the display depth of a frozen image.

<Operation method> : If you press the switch lever upward, a displayed depth becomes shallow. (The image is getting enlarged.) The least depth is obtained by pressing this switch continuously until the depth no longer decreases. : If you press the switch lever downward, a displayed depth becomes deepened. (The image is getting reduced) The greatest depth is obtained by pressing the switch continuously until the depth no longer increases.

1-4-5. ENTER This function changes over the control function when you are controlling various functions with the trackball. It is used mainly when inputting a measurement, a preset, a review, and comments. Press down on this and keep it depressed momentarily to finalize the measurement function. When used on the analysis or the REVIEW screen, the context menu is displayed. This is also used to relocate comments that have been previously input.

<Operation method> Example: Moving comments (1)

Position the cursor over the comment that you want to move and press on the ENTER switch, keeping it depressed momentarily. →

(2)

The selected comment becomes highlighted.

Using the cursor, move the comment and press the ENTER switch, keeping it depressed momentarily. →

The migration of the comment is established.

1-4-6. FOCUS The FOCUS function converges the ultrasound beam to make a clearer image. A focal point can be changed when the ultrasound beam is being transmitted. B mode image has eight transmission focal points, F1 to F8 in the depth direction. You can set the focus at up to any four of these points. In the case of an M mode image, one optimum focal point is set near the center of the display range. (The display range varies with the display depth and the M-WINDOW.) The above also applies when only an M mode image is displayed. In the case of a B/D mode display, one focal point is set according to the sample volume. (Only when you set the Auto) Also, when an M mode image or a D mode image in a B/* mode display is frozen, you can perform multi-stage focus setting. [Remark] You can not turn off all focal points. At least one focal point must be selected.

<Operation method> Select the auto focus or the manual focus on the menu. For details, refer to Section 6. "Touch panel". (1)

Press the FOCUS switch. →

(2)

The transmission focus position can be set.

Using the trackball, move the transmission focus position. →

Rolling the trackball up moves the transmission focus position to the shallow depth point, and rolling the trackball down moves the transmission focus position to the deep depth point.

[Remark] When the AUTO focus is set at two or more points, you can change the distance between the focal points by using rotary encoder 4. [Remark] The focus position can not go outside the displayed depth in AUTO focus. MN1-5481 Rev.2

1.SWITCHES and COMMENTS 1-4.Operating the various switches

[Remark] After changing the focus position to any place in AUTO focus, changing the depth with the DEPTH/RANGE switch changes the focus position to the optimum position according to the changed depth. [Remark] In Manual focus, the focus position can be positioned to the maximum depth for a particular probe being used. Furthermore, even if you change the depth, the focus position will remain unchanged.

Note If you set multiple focus points, that results in obtaining an image with high resolution, but decreasing the frame rate. Select the optimum setting so as to suit the desired body part while checking the acoustic power index.

1-4-7. FREEZE The FREEZE function freezes a moving image. When you press the FREEZE switch, the B mode image freezes upon the completion of one ultrasound wave scan, and the M and D mode images freeze immediately, or the M and D mode images freeze just after they are displayed completely. Also, stops counting the date and time and ultrasound transmission. [Remark] In order to protect the instrument, you can set the instrument so that the freeze condition automatically goes ON when you do not perform a panel operation for a certain period. (You can set this period to between 1 and 20 minutes using a preset. You can also turn this function OFF when you wish to use the monitor for a long period. For details, refer to Section 7. "PRESET".) By connecting an optional foot switch, you can turn the freeze function ON and OFF using either the FREEZE switch or the foot switch.

<Operation method> (1)

Press the FREEZE switch. →

The switch is lighted in orange, and the displayed image freezes.
