2-2. Name of each parts
The name of each part is shown in Figure 2 and the explanation for each part is listed in Table 1.
Figure 2 Name of each parts
Table 1 Name of each part and its explanation
Name Explanation
Ultrasonic radiation part Ultrasound is radiated from this part. The electronic sector
transducer is integrated underneath this part.
Front mark The side of the front 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.
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 “Cleaning, Disinfection and Sterilization” for cleaning,
disinfection, and sterilization procedure.
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.
If any abnormality is found in the image, please refer to the picture at section “1-1-1 Warnings and cautions” of
separate instruction manual “Safety”.
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 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
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.
Remove the probe after pushing the Freeze button
Probe will be damaged when do not remove the probe after stopping the transmission.
4-1. Temperature Control System
The tip of the probe contains a temperature sensor. This sensor monitors the surface temperature at the tip of the probe
in order to prevent damage to the body surface.
When the surface temperature exceed limit, the message appears on the equipment monitor.
1) When the surface temperature becomes 41°C
When the surface temperature becomes 41°C, the message “Probe temperature is higher than 41.0°C.” appears on the
equipment monitor.
2) When the surface temperature becomes 43°C
When the surface temperature becomes 43°C, the message “TTE thermal limit. Auto cooling mode in progress.”
appears on the equipment monitor and the acoustic output is automatically stopped. When surface temperature is below
40.5°C, This message disappears and restarts operation.
3 Under the following conditions, the probe tip gets hot easily and rapidly, so select “Saving”.
The ambient temperature exceeds 30°C.
Patient has a high body temperature.
Prolonged use is expected.
See the equipment mannual for the detail.
