TRANSDUCER PROBLEMS
Transducer not recognized by system (no B-mode imaging)
To ensure a positive connection, disconnect the transducer and reconnect it.
Inspect the metal contact pins on the transducer connector for any residue or
damage.
Inspect the scan module port for any residue or damage.
Insert the transducer into a different port on the system.
To determine a problem with the transducer or system, attach a different
transducer.
Disconnect the transducer. Power off the system. Power the system back on
and reattach the transducer to test for functionality.
If system still fails to operate any transducers, contact Mindray/Zonare Tech
Support.
IMAGING PROBLEMS
Poor B-mode image
Switch to a different transducer or probe port to see if the problem is with a
particular transducer or system port.
Ensure that there is an adequate supply of acoustic coupling gel and good
patient/transducer contact.
In the on-screen menu, under the Preset tab, select one of the factory default
settings (General, etc.) to determine possible maladjustment of user presets.
Adjust the various Doppler controls (gain, depth, frequency, etc.) to attempt to
resolve the problem.
Make sure the brightness and contrast settings of the LCD display have not been
altered from proper settings. For information about LCD display settings, see
LCD Display.
To ensure the quality of the gray scale resolution of the LCD display, use the
gray scale test pattern (via the Diagnostic menu) that is available. Ensure that all
shades can be visualized, making small adjustments to brightness and contrast
from factory defaults, as required, to see all intensities.
