Purpose
This manual provides information to assist service personnel in performing
maintenance, and repair procedures that may be required to support ZS3 Ultrasound
System.
The Mindray/Zonare ZS3 Ultrasound System is used for ultrasound evaluation of the
following applications: Opthalmic; Fetal; Abdominal (renal, GYN/Pelvic); Intra-operative
(abdominal, thoracic(cardiac), and vascular); Intraoperative (Neuro); Pediatric; Small
organ (thyroid, breast, testes, etc); Neonatal cephalic; Adult Cephalic/Transcranial; Trans-
rectal; Trans-vaginal; Trans-esoph.(non-Card); Musculoskeletal (Conventional);
Musculoskeletal (Superficial); Cardiac Adult; Cardiac Pediatric; Trans-esoph. (Cardiac);
Intra-cardiac; Peripheral vessel. Users include ultrasound imaging technicians
(sonographers) and physicians. Mindray/Zonare Ultrasound Imaging Systems may be
used in a hospital (e.g., imaging laboratory, emergency room, patient bedside, and
operating room), medical clinic, physician’s office or a mobile imaging center. Please
refer to the ZS3 Instructions For Use for more information.
The ZS3 Ultrasound System consists of two major components: 1) Cart; and, 2)
Transducer(s). The Cart contains the software driven imaging electronics and user
interfaces (keyboard, monitor, handles, etc.). It houses the microprocessor, memory,
amplifiers and power supplies for the microprocessor. It sends electrical currents to and
receives electrical pulses from the compatible transducers. The Cart performs the
calculations involved in processing the data to produce the displayed ultrasound
images. The ZS3 Cart is available in two options: with or without Echocardiography. The
Echocardiography option allows users to perform advanced cardiac and intracardiac
imaging and related functions beyond what is available without the echocardiography
option.
Included with the system are one or more Mindray/Zonare Curvilinear, Endocavity,
Linear, or Phased array transducers allowing for many clinical applications. Accessories
include, but are not limited to the Mindray/Zonare ZPAK Battery and off-the-shelf
components: bar code reader, foot pedal, printers, biopsy guides, ECG cables and a
wireless Ethernet interface. Case studies can be stored to USB memory stick, and other
industry standard archiving devices.

Before defibrillation, always disconnect the ECG cable connector from the
system and make sure the connector does not come in contact with other
persons or conductive surfaces, such as metal examination beds, trolleys,
and similar items.
Operating your system with ECG signals below 0.25 mV may cause
inaccurate results.
Warnings –TEE Transducer
The multiplane TEE transducer should be used only by a qualified physician
who has received appropriate training in proper operation of the probe and in
endoscopic techniques as dictated by current relevant medical practices.
Electrical Hazard: Any evidence of damage indicates the probe cannot be
used and should be returned to Mindray/Zonare for evaluation and repair.
Biological Hazard: Adequate cleaning and, if necessary, disinfection are
carried out to prevent disease transmission. It is the responsibility of the user
to verify and maintain the effectiveness of the procedure used. A single-use,
sterile disposable sheath for TEE purposes can be used.
Inspect the transducer connector pins for contamination or damaged pins that
might interrupt signal flow through the connection. Be sure to check pins
before connecting transducer to the Mindray/Zonare ultrasound system. If
pins are bent, broken, or missing, do not use the transducer and call
Mindray/Zonare Technical Support.
Immediately replace a transducer that exhibits any damage symptoms.
Before introducing the probe, do not rub or spray the tip of the probe with an
anesthetic agent.
Avoid forceful manipulations and excessive force in using the probe that could
result in patient injury.
Withdraw the probe only with the deflection control in the unlock mode and
with the distal end of the probe straight.
The use of a bite guard is mandatory. Failure to use the bite guard may result
in damage to the probe, which could result in a safety hazard. Damage to the
probe due to biting is not covered by the probe's warranty.
Check if the maximum deflection of the tip is 90°to 120°upward, 60°to 90°
downwards and 30°to 45°left/right. If the deflection shows an unwanted
amount of free play or exceeds the maximal deflection angles given above,
do not use the probe. Contact the service organization to re-adjust the
steering of the probe. In this way, the risk of "buckling" or "U-turning" of the
probe in the esophagus is minimized.
Avoid damage to the probe by allowing nothing to protrude beyond the case
when closing the lid.
Prior to cleaning any device, turn off the system and disconnect power cord
from AC power source to avoid electrical shock.
Always use protective eyewear and clothing when cleaning or disinfecting the
transducers.

ZS3 Service Manual
Page 18 of 295
Do not allow the disinfectant to come in contact with metal surfaces
(transducer connector). Use a soft cloth and warm soapy water to remove any
disinfectant that remains on metal surfaces.
Keep the control handle and transducer 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 probe up to the 100cm marker on
the P8-3 TEE and 70cm marker on the P8-3m TEE shaft may be placed into
a disinfection solution.
Do not use other disinfection methods like Iodine, Steam, Heat or Ethylene
Oxide.
When servicing the ZS3 System, always be sure to turn the circuit breaker to
the OFF position.
Precautions
Transducers are individually licensed according to system configuration. Only
the following transducers are available without an advanced feature

3mTEE and P8-3TEE. The A2CW and A5CW transducers are enabled if the
system is configured with "CW Enabled", and can be used under either the
Echocardiology (optional) or the Advanced Vascular Imaging (mandate)
mode. Attempting to use any other transducers will result in an error
message.
Be aware of the potential hazards associated with the environment where the
ultrasound systems will be used. The systems and/or the external equipment
can be damaged if signal levels are not appropriate. If peripheral equipment
not specifically authorized by Mindray/Zonare is to be connected to the
system, it must meet all applicable electrical safety standards that apply to the
system in order to maintain Mindray/Zonare’s safety integrity. Any equipment
not supplied by Mindray/Zonare must be approved by Mindray/Zonare. Use of
non-Mindray/Zonare-approved equipment may result in an unsafe condition,
impair operation of the ultrasound system, impair diagnostic capabilities, and
void your warranty or service contract coverage.
Mindray/Zonare transducers have a specific range of acceptable application
use. Users are advised to restrict each transducer’s use to those applications.
Excessive bending, twisting, pulling, dragging, or compression of transducer
cables may cause failure or intermittent operation of the system. Avoid rolling
the cart wheels over cables. Use of cable hooks is recommended to minimize
chance of damage to cables.
If a transducer that has not been approved and licensed for use with the
ultrasound system to which it is connected, or if a licensed transducer is not
properly connected, the corresponding transducer identification data will not
display on the LCD Display. Imaging will be disabled. Resolve this issue
before continuing use.

The ultrasound system and/or the transducer could be damaged if a non-
approved transducer is connected.
Improper cleaning or disinfection of patient applied parts may cause
permanent damage. Carefully review the manufacturer’s directions for any
component used with Mindray/Zonare ultrasound systems. MINDRAY
assumes no liability with respect to single-use devices that are reused,
reprocessed, or resterilized and makes no warranties, expressed or implied
(including the warranties of merchantability or fitness for a particular use),
with respect to such devices.
Use of peripherals or other equipment not provided by Mindray/Zonare may
result in system damage or degraded performance. Carefully review the
labeling of any such equipment before connecting to the Mindray/Zonare
system.
Improper setting of imaging controls may obscure diagnostically valuable
information in the display. The factory default preset maps were preselected
as appropriate for most imaging circumstances. Improper user configuration
of custom presets may obscure diagnostically valuable information.
Mindray/Zonare ultrasound systems are manufactured in compliance with
existing electromagnetic immunity (EMI) and electromagnetic compatibility
(EMC) requirements. Use of the systems in the presence of an
electromagnetic field can cause degradation of the ultrasound image.
Electrostatic discharge (ESD), or static shock, is a naturally occurring
phenomenon. ESD is common in low humidity, which can be caused by
heating or air conditioning. ESD shock occurs when electrical energy is
discharged from one body, to a differently charged body. To lessen the
occurrence of ESD, use antistatic spray on carpets and flooring, and antistatic
mats.
To minimize potential ESD damage and electrical contact contamination,
avoid touching the metal contacts for the transducer connections, at both the
ZS3 port and the transducer connector.
If the ZS3 System has been moved between environments with extremes of
temperature and/or humidity, allow the ZS3 System to rest for at least 30
minutes in a controlled environment before using.
Do not use the ultrasound system if any error message displays on the
screen.
Do not block airflow to any ventilation holes on the system.
Do not submerge the transducer past the points indicated in ‘Mindray/Zonare
Transducers Cleaning and Disinfection’.
Do not spill liquid on the systems or transducers.
Using a non-recommended cleaning or disinfectant solution, incorrect solution
strength, or immersing the transducer deeper or longer than indicated can
damage the transducer. Damages linked to the use of disapproved chemicals
are not covered under product warranty or service contract.
The use of non-shielded cables may result in increased emissions and
decreased immunity to external signals
Operating the systems in the presence of external electromagnetic fields can
degrade the quality of the ultrasound image. High-frequency devices, such as

ZS3 Service Manual

electro-surgical devices, can produce image artifacts. If required, a review of
the local electromagnetic environment may be required to minimize the
sources of external noise generators.
The use of non-Mindray/Zonare approved cables and accessories may result
in increased radiated emissions as well as decreased immunity to external
signal fields.
Before beginning to image a new patient, be sure to conclude any in-progress
patient exam by pressing the New Patient key. Failure to do so will result in
any subsequent storing of images being mistakenly written to the previous
patient exam directory.
Some components or devices such as transducer covers used with
Mindray/Zonare systems are for single-patient use only. Reuse, reprocessing,
or re-sterilization of these devices may compromise their structural integrity.
Any image sets stored on the system, which are not identified by patient
name and number, will be stored with a unique number based off of the
system ID.
Exercise care in adjusting all settings to avoid obscuring low-level signals that
may have diagnostic value. Improper settings can seriously degrade image
quality.
Do not touch exposed metal of transducer connector.
Validate all entries in the Measurement Summary.
Ultrasound imaging capabilities can vary from patient to patient. Ultrasound
should be used as one component in a comprehensive diagnostic plan.
Never leave a probe in the disinfection solution for more than the specific time
by the disinfection manufacturer. Please refer to the instructions for use that
came with the disinfectant for minimal required exposure times. Do not forget
to rinse the probe directly after disinfection.
Only use water-soluble acoustic coupling gel. Other coupling gels can cause
probe damage.
Long-term exposure to ultrasound should be minimized. Although there have
been no confirmed adverse effects produced by diagnostic levels of
ultrasound, unnecessary patient exposure to ultrasound energy should be
avoided, especially in the Doppler mode.
Use of a non-compatible USB Memory Stick may result in file corruption or
long file transfer times. Please confirm proper operation of any memory stick
prior to attempting to use for clinical data.
Make sure the ZS3 System has fully completed downloading upgrades,
importing/exporting, or collecting log data to the USB Memory Stick before
removing it from the ZS3 System. Failure to do so will result in loss of data.
Review the ZS3 DICOM conformance statement before integrating with any
PACS system.
Validate Structured Report export prior to clinical use.
Use-time from the optional ZS3 battery pack will vary depending on the
system usage and battery conditioning. Ensure the battery is adequately
charged before starting a procedure without AC main power.
Export patient studies in a timely manner. Do not use the system storage as
the sole location of patient studies for an extended period of time.
