• In the onscreen menu under the Preset tab, select one of the factory default
settings (General, etc.) to determine possible maladjustment of user presets.
• Ensure an adequate supply of acoustic coupling gel and good patient/
transducer contact.
• Switch to a different transducer to determine if the problem is
transducer-specific.
No (or poor quality) Color mode image or PW Doppler
• Make sure the brightness and/or contrast settings for the LCD Display have
not been altered from proper settings. For information about LCD Display
settings, see
page 2-6.
NOTE: To ensure the quality of the grayscale resolution of the LCD Display, use
the grayscale test pattern (via the Diagnostic menu) available on the
SmartCart/
SmartCart sp
. Ensure that all shades can be visualized, making small
adjustments to brightness and contrast from factory defaults, as required, to see
all intensities.
• Make adjustments to the various Doppler controls (Gain, Filter, Scale) to
attempt to resolve problem.
• Ensure that the scanning angle between the transducer face and the direction
of blood flow is optimized.
• In the onscreen menu under the Preset tab, select one of the factory default
settings (General, etc.) to determine possible maladjustment of user presets.
• Ensure there is an adequate supply of acoustic coupling gel and good patient/
transducer contact.
• Switch to a different transducer to determine if the problem is
transducer-specific.
No (or poor quality) CW Doppler
If using the CW Aux transducer:
• Disconnect the CW Aux connector from the front of the SmartCart and then
reconnect to ensure electrical continuity.
• Try using a different CW Aux transducer.
• Try using a P4-1c transducer to perform CW mode operation.
If using the P4-1c transducer:
• Try using the CW Aux transducer.
• Unplug the P4-1c connector from the MTP and reconnect to a different port on
the MTP.
• Try operating the P4-1c transducer in PW Doppler mode.
• If system still fails to operate CW Doppler, contact ZONARE Technical
Support.
No ECG operation
• Activate ECG operation by pressing the ECG key on the SmartCart QWERTY
keyboard.
