MQSA Quality Control Tests   |   57

3 Use a dry, soft, clean cloth to wipe off the residue.

NOTE: Always wipe off water and other stains immediately to avoid 

damage to the screen.  Do not exert excessive pressure on the 
display screen as this can damage the LCD module.

4 Check the screen to verify that it is free of dust, fingerprints, and 

other marks.

The screen must be free of dust, fingerprints, and other marks.  
If these results are not obtained, the source of the problem must 
be identified and corrective action taken before any further 
mammographic images are reviewed or interpreted using 
the Dome display.

To complete the daily control test record

1 Open the Test Wizard and click Daily Quality Control Test. 

2 Enter the facility ID: facility name, room, and tester initials.
