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 that accompanies this user guide. A list of disinfectants and disinfection
methods that the transducer can withstand are listed in the Product Data sheet.
Sterile cover is available. See the Product Data sheet for more details.
WARNING
If at any time the scanner malfunctions, or the image is severely distorted or degraded, or
you suspect in any way that the scanner is not functioning correctly:
• Remove all transducers from contact with the patient.
• Turn off the scanner. Unplug the scanner from the wall and make sure it cannot be
used until it has been checked.
• Do not remove the scanner cover.
• 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.

8830 User Guide (BB1837-C) 7
Starting Scanning
All equipment must be cleaned and disinfected before use.
Connecting the Transducer
The transducer is connected to the scanner using the array Transducer Socket on the
scanner. To connect, the transducer plug’s locking lever should first be in a horizontal
position. Align the plug to the scanner socket and insert securely. Turn the locking
lever clockwise to lock in place.
When connected, the transducer complies with Type B requirements of EN60601-1
(IEC 60601-1).
Changing Frequency
The Multi-Frequency Imaging (MFI) facility enables you to select the scanning
frequency. See the applicable scanner 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 gel to the tip of the transducer. 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 scanning. Re-
apply the gel frequently to ensure good screen images.
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.
WARNING
Use only water-soluble agents or gels. Petroleum or mineral oil-based materials may harm
the cover material.

8830 User Guide (BB1837-C) 9
To mount biopsy attachment UA1250 ready for use:
Note: When mounted the attachment lock screw (item A in Fig. 3) should be on the
side of the transducer handle opposite to the transducer’s control button.
1 Mount the attachment bracket on the transducer. Fit the indentations in the sides
of the bracket over the raised metal knobs on either side of the transducer handle.
2 Fix the attachment bracket in position by tightening the attachment lock screw
(item A in Fig. 3). Tighten the screw up to its “locking point”, after which it will
not be possible to tighten the screw anymore.
3 The biopsy attachment should now be fixed solidly to the transducer’s handle.
4 Using the needle guide locking screw (item B in Fig. 3), adjust the needle guide
according to the size of needle to be used.
The distance from the guide channel entrance of the puncture attachment to the first
dot on the scan image puncture line is 56 mm. The distance between the dots is
10mm (see Fig. 9).
All parts of the puncture attachment can be autoclaved or disinfected by immersion
in a suitable solution. See Care, Cleaning and Safety that accompanies this user
guide.
