General Information
Product specifications for this transducer can be found in the Product Data sheet that
accompanies this user guide.
Acoustic output data and data about EMC (electromagnetic compatibility) for this
transducer are in Technical Data (BZ2100) that accompanies this user guide. A full
explanation of acoustic output data is given in your system user guide.
Service and Repair
Caring for the Transducer
The transducer may be damaged during use or processing, so it must be checked
before use for cracks or irregularities in the surface. It should also be checked
thoroughly once a month following the procedure in
Care, Cleaning & Safety .
Cleaning and Disinfection
To ensure the best results when using BK Medical equipment, it is important to
maintain a strict cleaning routine.
Full details of cleaning and disinfection procedures can be found in
Care, Cleaning
& Safety
, which accompanies this user guide. A list of disinfectants and disinfection
methods that the transducer can withstand are listed in the Product Data sheet.
Sterile covers are available. See the Product Data sheet for more information.
WARNING
If at any time the system malfunctions, or the image is severely distorted or degraded, or you
suspect in any way that the system is not functioning correctly:
• Remove all transducers from contact with the patient.
• Turn off the system. Unplug the system from the wall and make sure it cannot be used
until it has been checked.
• Do not try to repair the system yourself.
• Contact your BK Medical representative or hospital technician.
WARNING
Always keep the exposure level (the acoustic output level and the exposure time) as low as
possible.
WARNING
Service and repair of BK Medical electromedical equipment must be carried out only by the
manufacturer or its authorized representatives. BK Medical reserves the right to disclaim all
responsibility, including but not limited to responsibility for the operating safety, reliability
and performance of equipment serviced or repaired by other parties. After service or repairs
have been carried out, a qualified electrical engineer or hospital technician should verify the
safety of all equipment.

Starting Imaging
All equipment must be cleaned and disinfected before use.
Connecting the Transducer
The transducer is connected to the system using the array transducer socket on the
system. To connect, the transducer plug’s locking lever should first be in a horizontal
position. Align the plug to the system socket and insert securely. Turn the locking
lever clockwise to lock in place.
When connected, the transducer complies with Type BF requirements of EN60601-1
(IEC 60601-1).
Changing Frequency
The multifrequency Imaging (MFI) facility enables you to select the imaging
frequency. See the applicable system user guide for instructions. The selected
frequency is displayed at the top of the screen.
Using a Transducer Cover
The transducer should be enclosed in a transducer cover or a standard condom. See
the Product Data sheet for a list of available transducer covers.
Apply sterile gel to the tip of the transducer or fill the cover with 1 to 2 ml of sterile
water. This improves the screen images by preventing image artifacts caused by air
bubbles.
Pull the transducer cover over the transducer.
Gel also creates a good acoustic contact between the skin and the transducer;
therefore, apply a small amount to the outside of the cover prior to imaging. Re-apply
the gel frequently to ensure good screen images.
WARNING
Users of this equipment have an obligation and responsibility to provide the highest degree
of infection control possible to patients, co-workers and themselves. To avoid cross
contamination, follow all infection control policies for personnel and equipment established
for your office, department, or hospital.
WARNING
Keep all plugs and sockets absolutely dry at all times.
WARNING
Because of reports of severe allergic reactions to medical devices containing latex ( natural
rubber), FDA is advising health-care professionals to identify their latex-sensitive patients
and be prepared to treat allergic reactions promptly.

Changing Orientation
To change the orientation of the image on the monitor, refer to the applicable system
user guide for instructions.
Disposal
When the transducer is scrapped at the end of its life, national rules for the relevant
material in each individual land must be followed. Within the EU, when you discard
the transducer, you must send it to appropriate facilities for recovery and recycling.
See the applicable system user guide for further details.
WARNING
Use only water-soluble agents or gels. Petroleum or mineral oil-based materials may harm
the cover materials.
WARNING
For contaminated disposals such as transducer covers or needle guides, follow disposal
control policies established for your office, department or hospital.
