1-2-1. Warnings and safety information
Warning
Follow the information in this manual and the documentation supplied with any equipment used
together with this probe.
Use that is not in accordance with the supplied documentation can result in a serious or moderate
injury, equipment breakdown, or physical damage that impairs operation.
Be sure to preparations for use.
Use the probe without noticing an abnormal condition can result in injury to the operator or patient.
If any abnormalities are noted on the probe in the start up check, immediately stop using it and
contact one of our ofces and/or distributor's ofces listed on the back cover.
See section 3-1 “Start up check”.
Do not use on the eyes.
This probe is not intended for use on the eyes. The acoustic output can have an adverse effect on
the eyes.
Do not attempt to disassemble, modify, or repair the probe.
Electric shock or other unforeseen accidents could result. Contact one of our ofces and/or
distributor's ofces listed on the back cover to request repair.
Clean, disinfect and sterilize before using the probe as necessary.
Perform properly wash, disinfect and sterilize after use.
Otherwise, there is a risk of infection. Note that the probe is not sterilized at the factory.
Before using the probe rst, be sure to wash, disinfect and sterilize it as required.
Wear medical gloves during examination.
Conducting examinations with the bare hands can expose the operator to a risk of infection.
Dispose of probes used for patients with Creutzfeldt-Jakob disease.
Otherwise, there is a risk of infection to the operator or patient. Currently, there are no methods
for washing, disinfecting and sterilizing probes which have been used on patients aficted by
Creutzfeldt-Jacob disease.
When using ultrasound contrast agent, follow the supplied documentation.
Unexpected accidents could result. Check the state of the patient and take appropriate precautions
to avoid side effects.
Do not use the probe fallen on to oor.
Otherwise, there is a risk of infection. Stop the operation and perform the procedure in section 8
"Periodic Inspection", section 5 "Washing, Disinfection and Sterilization" and section 3-1 "Start up
check".
Caution
Constantly check for anything abnormal about the patient’s condition and probe.
Continued use without noticing that an abnormal condition has occurred can result in an electric
shock and injury to the operator or patient. If an abnormal condition occurs, immediately move the
probe away from the patient and stop use of the probe.
The probe is vulnerable to damage by impact. Therefore, handle it with care.
There is a risk of damage to the probe when the probe is fallen or hit somewhere.
Do not use this probe with other equipment except for those specically approved in the manual.
Use with unapproved equipment can result in an electric shock, burn, or other injury to the patient
or operator and damage to the probe and the other equipment.

MN1-1156 Rev. 13
Scan for the minimum length of time necessary for the diagnosis and at the lowest suitable output.
Overuse can adversely affect the internal tissues of the patient.
For details about the acoustic output, please refer to the documentation supplied with the ultrasound
diagnostic instrument.
Regularly perform maintenance inspection and safety tests of the ultrasound diagnostic instrument
and probe.
If you use equipment for a long period of time, it can reduce the performance, or cause smoke or
re. If anything unusual occurs, immediately stop using it and contact one of our ofces and/or
distributor's ofces listed on the back cover.
Use, move and transport the probe under the environmental conditions specied in this manual.
Otherwise, it may be damaged.
See section 2-5 "Environmental conditions" and section 7-4 "Environmental conditions during
transportation".
1-2-2. Washing, disinfection and sterilization precautions
Warning
Wear protective gloves and other protective gear during washing, disinfection and sterilization.
Handling of the probe with your bare hands before disinfection or sterilization can result in an
infection.
After soaking in cleaning agents, thoroughly wash the probe with running water.
Residual chemicals can cause an adverse reaction on the bodies of the operator or patient.
After chemical disinfection and sterilization, thoroughly wash the probe with sterilized water.
Residual chemicals can cause an adverse reaction on the bodies of the operator or patient.
Perform aeration completely after gas disinfection and sterilization.
Residual gas can cause an adverse reaction on the bodies of the operator or patient.
Do not wash, disinfect or sterilize using procedures other than those specied in this manual.
Infection could result due to incomplete washing disinfection or sterilization. It can also result in
damage to the probe or reduced performance. The probe cannot withstand autoclave sterilization or
boiling and other types of sterilization at temperatures exceeding 60°C (140°F).
For details on the usage conditions of chemicals and sterilization procedures, refer to the
documentation supplied with the respective chemical or sterilization equipment.
Infection could result due to incomplete disinfection or sterilization.
This could also cause deterioration of the probe.
Caution
Do not place the probe tip in any liquids beyond the range
shown in the gure right.
The connector which liquid has intruded can cause the
malfunction of the probe and the ultrasound diagnostic
instrument. In this case immediately stop use and contact one
of our ofces and/or distributor's ofces listed on the back
cover. 21mm or less

2. Specications and Parts name
2-1. Principles of operation
This probe and the ultrasound diagnostic instrument enable image diagnosis using ultrasonic waves. These
instruments operate under the principles described below.
(1) When an electric pulse signal is applied from the transmitter to the transducer of the probe, the
transducer operates by converting electrical vibrations to mechanical vibration energy for emitting
pulse-shaped ultrasonic waves into the body part contacting the transducer or into liquid or other
medium.
(2) The emitted ultrasonic waves are reected by boundaries with different acoustic characteristics (acoustic
impedance) within the body.
(3) The transducer is also used to receive reected ultrasonic waves. The transducer vibrates mechanically
due to the received ultrasonic vibrations and uses an electro-mechanical conversion operation to
convert the received mechanical vibrations to electric energy. The received echo is also converted to
electric signals and a brightness modulation operation is used to convert the electric pulses to shades of
brightness for forming an image.
