Table 1 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.
Front side The side 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 and sterilization
Conrm that the probe is certainly cleaned and sterilized. The degree of reprocessing depends on the intended use.
Please refer to the separate instruction manual “Cleaning, Disinfection and Sterilization“ for cleaning 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.
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.
