• 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

. 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.
