CAUTION
If the optional deadman handswitch is installed on the scanner, press and hold
handswitch before pressing the Scan button, and continue to hold handswitch down for
the duration of the exposure (X-ray light on). Early release of the handswitch stops the
exposure and the Fault light turns on. The patient will have to be re-scanned.
Panel Calibration
It is recommended that Panel Calibration be performed once a week.
PanelCal is performed in both landscape and portrait (V17 systems only) positions for 4 x 4 and
2 x 2 resolutions. Several tests run as part of the panel calibration. A pie chart displays status.
Run Panel Calibration
1. From Utilities menu, select PanelCal.
2. Ensure the field of view on the scanner is clear.
3. Press . The scanner initializes.
4. When prompted, press the Scan button on the operator control box. An audible alarm is
sounded and the X-ray ON light is illuminated during radiation exposure.
5. You will be prompted to press the Scan button for each test.
NOTE: The panel will rotate to the portrait position at the start of the portrait tests (V17
systems only).
6. When Panel Cal is complete, Calibration Complete is displayed.
7. Press to display Complete screen and select another option.
Panel Calibration Failure
If the calibration fails, the following message is displayed:
