1 Safety Information
1.1 SafetyClassication
Pleaserefertothesafetyclassicationinformationintherelatedoperator’smanualforthe
ultrasonicdiagnosticsystemthatmatcheswiththistransducer.
1.2 Safety Precautions
Pleasereadthefollowingprecautionscarefullytoensurethesafetyofthepatientandthe
operatorwhenusingthistransducer.
DANGER
DO NOT use flammable gases, such as anesthetic gas or hydrogen, or flammable
liquids such as ethanol, near this system, because there is danger of explosion.
WARNING
●This ultrasonic transducer is only for use with the specified ultrasonic diagnostic
system. Please refer the ultrasonic diagnostic system operation manual to select
the proper transducer.
●The multiplane TEE Transducer should be used only by a qualified physician who
has received appropriate training in proper operation of the transducer and in
endoscopic techniques as dictated by current relevant medical practices.
●The multiplane TEE transducer is a precision instrument, which must be handled
with care. It may be damaged when dropped or abused. In particular, do not allow
the ultrasonic window in the tip to come into contact with a sharp object. Do not
touch this window unnecessarily. Never exert force onto the window.
●To avoid injury to the patient, if any irregularity, substandard function or unsafe
condition is observed or suspected, the TEE transducer should not be used.
●Keep the control handle and system connector out of any cleaning or disinfection
solutions. The control handle and cable may be cleaned with a damp cloth, but
only the distal end of the transducer up to the 100 cm marker on the shaft (70 cm
for P8-3Ts) may be placed into a disinfection solution.
●To avoid injury to the patient and damage to the transducer, use a bite-guard
during all transesophageal exams.
●The use of a bite-guard is mandatory. Failure to use the bite-guard may result in
damage to the transducer, which could result in a safety hazard. Damage to the
transducer due to biting is not covered by the transducer’s warranty.

Safety Information
2 Operator's Manual
●To avoid injury to the patient, avoid forceful intubation pressure which can
cause lacerations of the gastrointestinal tract with attendant and subsequent
perforation.
●The up/down and/or left/right deflection may after prolonged use develop an
unwanted amount of free play. In that case, contact the service organization
to readjust the steering of the transducer. In this way, the risk of “buckling” or
“U-turning” of the transducer in the esophagus is minimized.
●Confirm that the transducer and cable are normal before and after each
examination. A defective transducer may cause electric shock to the patient.
●When using intra-cavity transducers, do not activate the transducer outside the
patient’s body.
●The connector is not watertight, and should always be kept dry. The control unit,
although spray-watertight, should not be immersed.
●Do not subject the transducer to shock. A defective transducer may cause electric
shock to the patient.
●This equipment contains no operator serviceable components. To prevent electric
shock, do not remove any covers or panels.
●DO NOT use the transesophageal probe with the defibrillator.
CAUTION
●When using this transducer, wearing medical gloves can help to prevent infection.
●To avoid inadvertent damage to the transducer, read this user guide before
handling and cleaning the TEE transducer.
●Be sure to use ultrasound gel. Please use the ultrasound gel compliant with the
relevant local regulations.
Only use water-based coupling gel.
●Under normal conditions at full acoustic power the temperature of the tip
does not exceed 43°C. Follow the instruction in this user manual to check this
regularly.
●Do not use the carrying case for storing the transducer. If the carrying case is
used for storage, it may become a source of infection.
●It is required to practice ALARA when operating ultrasound system. Minimize the
acoustic power without compromising the quality of images.
●The transducer and accessories supplied with it are not delivered disinfected.
High-level disinfection is recommended before use.
●Disposable components are packaged sterile and are single-use only. Do not use
if integrity of packaging violated or if expiration date has passed. Please use the
disposable components compliant with the relevant local regulations.
●Please use the disinfection solution that recommended in this operator’s manual,
otherwise Mindray will not be liable for damage caused by other solutions. If you
have any questions, please contact Mindray Customer Service Department or
sales representative.

Safety Information
Operator's Manual 3
●Before introducing the transducer: do not rub or spray the tip of the transducer
with an anesthetic agent.
●The damage of the transducer may be caused by the contact of improper gel or
cleaner:
–DO NOT dip the transducer in the strong polar solutions of ethanol, chloride
of lime, ammonium chloride, acetone and formaldehyde.
–DO NOT contact the transducer with solution or ultrasound gel containing oily
medium such as mineral oil or lanoline.
NOTE:
●Read the following precautions to prevent the transducer from malfunction.
– Before connecting or disconnecting the transducer, freeze or turn off the
ultrasonic diagnostic system.
– Clean and disinfect the transducer before and after each examination.
●Repeated disinfection will eventually damage the transducer, please check the
transducer’s performance periodically.

3 Transducer Controls and Inspection
3.1 Inspection before Use
Theendoscopeisdesignedforone-handoperationofthedeflectionandscanplane
controls.Themechanicaloperationandphysicalintegrityofthetransducershouldbe
checkedaftertakingitoutoftheboxandpriortoeachexam.
Ifanyabnormalityisfound,immediatelystopusingthetransducerandcontactMINDRAY
CustomerServiceDepartmentorsalesrepresentative.
WARNING
To avoid injury to the patient, if any irregularity, substandard function or unsafe
condition is observed or suspected, the TEE transducer should not be used.
3.1.1 Visual and Tactile Inspection
ThevisualandtactileinspectionshouldbeperformedontheTEEtransduceraftertakingit
outoftheboxandpriortoeachexam.
WARNING
To avoid injury to the patient, do not use the transducer if any metallic protrusions,
holes, rough spots, cracks, or dents are found.
Inspectcontents:
1. Visuallyexamineandfeelallportionsofthetransducerbeforeuse,especiallythe
gastroscopeshaftandtheexiblesectionatthedistalendofthegastroscope.Perform
theinspectionoftheexiblesectionbothwiththetransducerdeectionstraightand
deflected.Thereshouldbenodiscontinuities,bumps,dents,holes,abrasions,bite-
marksoranyotherevidenceofwearordamagefound.
2. Thehardplasticsectionatthedistalendofthetransducershouldbesmoothand
rmlyattachedtothegastroscopeshaft.
3. Thecableandtheconnectorthatattachthetransducertotheultrasoundconsole
shouldbefreefromevidenceofdamage.

3.1.2 TipDeectionControl
WARNING
●If the deflection shows an unwanted amount of free play, do not use the
transducer. Contact the service organization to re-adjust the steering of the
transducer. In this way, the risk of "buckling" or "U-turning" of the transducer in
the esophagus is minimized.
●To avoid damaging the transducer, do not deflect the transducer tip using finger
pressure directly on the tip, as this may permanently damage the internal control
wires.
Thetipdeectionbrakeinspectionshouldbeperformedonthetransduceraftertakingitout
oftheboxandpriortoeachexam.
1. Deflectthetipinallfourdirections(P8-3Ts:up/down)andconfirmthattheangleis
withintherangesspeciedabove(withreferencetotheendoscopeshaft).
2. Conrmthatthedeectioncontrolsoperatesmoothly.
3. Checkthatwhenthedeectioncontrolsareintheneutralpositionthatthetransducer
tipisalsoinaneutralposition(undeected).
