7.5.3. To Adjust the Needle Guide Line

The needle guide bracket was calibrated during manufacture. However, certain events may cause
the bracket alignment to shift, and new calibration required.
1. Calibrate the needle guide under any of the following conditions:
a) The first time a needle guide is used with a given transducer.
b) Any time the needle guide or transducer has been dropped or struck against a
hard surface.
c) After repeated use.
2. Do not use the needle guide bracket if the needle does not track with the guide during
calibration.
To calibrate the guide line
1. Assemble the needle guide bracket on the transducer, and use the transducer to image a water
bath or needle guide phantom.
2. From the Needle function on the B-mode touch screen, press the Calibration button on the
touch screen to display the Angle and Position paddle button.
 Use the Position paddle to adjust the line horizontally until the origin aligns with the
actual needle.

Use the Angle paddle to adjust the angle of the line until the entire line aligns with
the actual needle.
 Any changes will be saved as the default value automatically.
