Probe tip
Figure 2 Name of each parts
Table 3 Name of each part and its explanation
Name Explanation
Ultrasonic radiation part Ultrasound is radiated from this part. The electronic
convex transducer is integrated underneath this part.
Orientation mark The side of the orientation mark corresponds to the side
of the orientation mark on the image.
Probe tip This part is gripped during operation.
Cable Cable transfers electric input/output signals.
Connector The connector is the part which is connected to the
ultrasound diagnostic instrument.
Caution
Do not pull, bend, twist, or apply excessive force to the cable.
The probe may malfunction due to cable disconnection.
Do not subject the ultrasonic radiation part to hard impact.
The impact may cause damage to the transducer, and that results in noise or no echo in the image.
In most cases, the ultrasonic radiation part itself is not damaged because the part is made of elastic
material.

3. Preparations before use
This chapter describes preparations needed to use the probe safely. Please prepare the probe prior to each use by
following the instructions below.
3-1. Visual check
Visually check the probe tip, ultrasonic radiation part, cable, and connector.
If any holes, indentations, abrasion, cracks, deformation, looseness, discoloration, or other abnormalities are found, do
not use the probe.
Check also the options as necessary.
3-2. Conrmation of cleaning, disinfection, and sterilization
Conrm that the probe is certainly cleaned, disinfected, and sterilized. The degree of reprocessing depends on the
intended use. Please refer to the separate instruction manual “Disinfection and Sterilization“ for cleaning, disinfection,
and sterilization procedure. Conrm also that options are properly cleaned, disinfected, and sterilized.
3-3. Operation check
Connect the probe to the ultrasound diagnostic instrument and check that the displayed scan type and frequency
correspond to those of the probe. Check also that there is no abnormality in the image.
Remark: Please refer to the documentation supplied with the ultrasound diagnostic instrument for how to connect the
probe and information displayed on the monitor.
If the probe is operated in still air, brightness on the top of the image may be non uniform, but this does not
affect the performance of the probe.
Warning
Make preparations prior to each use.
The operator and the patient may be injured if the equipment has any abnormality.
If any abnormality is found in the equipment, stop using it and contact our ofce written on the back
cover.
Caution
Do not use the probe if the displayed scan type and frequency displayed do not correspond to those
of the probe. Incorrect acoustic output can result in burns or other injuries to the patient. Contact our
ofce written on the back cover.

4. Operation
This chapter describes the operation of the probe and how to attach/release Magnetic Position Sensor and Magnetic
Position Sensor Attachment.
4-1. Operation
Place the ultrasonic radiation part of the probe onto the skin surface. An image of the region of interest is displayed
on the monitor of the ultrasound diagnostic instrument. For details on displaying and adjusting the image, refer to the
documentation supplied with the ultrasound diagnostic instrument.
Caution
Do not operate the probe with excessive force.
Use with excessive force could result in injury to the patient.
Scan for minimum time necessary at the lowest possible acoustic output.
Acoustic output may affect the patient’s internal tissues.
For details about the acoustic output, please refer to the documentation supplied with the ultrasound
diagnostic instrument.
Do not touch the connector terminal pin of the probe.
Electrostatic discharge may result in malfunction of the probe.
Do not touch the probe connector of the ultrasound diagnostic instrument and the patient at the same
time. It can cause electric shock to the patient.
