Cleaning

Removing and attaching the digital capture unit
When removing the the digital capture unit from the camera (or protective cover from the
back), hold down the magazine catch lock button while sliding the magazine catch as in
illustration 1.
When attaching the back to the camera (or the protective cove to the back), repeat the
procedure as in illustration 2. Avoid trying to just 'snap' the digital capture unit or protec-
tive cover into place without using the buttons.
Cleaning the CCD Infrared Filter
If you see dark or colored spots or lines in your images, then you may need to clean the
outer surface of digital capture unit's infrared (IR) filter. In most cases, the careful use of
compressed air will be adequate, but sometimes small particles will get stuck to the surface
of the IR filter, requiring for a more thorough cleaning, involving either fluid or wipes. For
a good safe cleaning, follow descriptions below.

WARNING: never attempt to remove the glass filter from the front of the CCD—you will
probably ruin the CCD if you do so. If dust manages to get between the IR filter and CCD,
please contact your Hasselblad dealer for assistance.
Basic cleaning procedure
1. Discharge any static electricity that may have built up on your body by touching the
digital capture unit housing.
2. While keeping the magazine catch lock depressed, slide the magazine catch to the
right.
3. The top of the digital capture unit will be released (while it rests on the magazine
retaining hooks) and it can be swung away from the camera body.
4. Clean the outside surface of IR Filter by spraying it with clean compressed air. If this
is not enough, then use one of the procedures outlined below.
5. If you still see spots on your shot after you have cleaned the outside of the infrared
filter, then you may have dust on either on the back side of the IR filter or on the CCD
itself. This can only be removed at the Hasselblad factory. Contact your Hasselblad
dealer for assistance.
6. When reattaching the digital capture unit to the camera, keep the magazine catch
lock depressed and the magazine catch to the right. Check that the back is firmly in
place.
