Usage Precautions

Be sure to always observe the following precautions.
1. Never use general-purpose image retouching software to edit or overwrite the images files for the CR-DGi Image
Viewer. The study information and image information written into the image file can be corrupted or become
unreadable.
2. Do not use the preview screen in Windows XP to rotate an image file for the CR-DGi Image Viewer. If an image is
rotated, the study information and image information written into the image file can be corrupted or become
unreadable.
3. If the display is not set to full color, the colors may not be displayed properly. To set the display colors in Microsoft
Windows, select Display Properties, go to Settings, and then check that the Colors is set to True Color (24 bit or
32 bit).
4. Use the CR-DGi Image Viewer in a system environment with the proper security protection. The CR-DGi Image
Viewer itself does not have any security protection functions.
5. In CR-DGi Image Viewer, the study information and image information are saved to the image in clear text.
6. Be sure to always test beforehand to check that images are captured and saved properly.
7. The user of the CR-DGi Image Viewer needs to belong to the member of the Power Users group or the
Administrators group.
IMPORTANT
Original images captured by the CR-DGi are reversed horizontally and vertically and do not have an
aperture mask.
Be sure to always use the CR-DGi Image Viewer to rotate the image 180 degrees and add an aperture
mask to the image.
