Do not remove the IR filter as this will make it virtually impossible to get the filter
perfectly clean. Therefore, we strongly advise against you attempting to clean either
the inside of the IR filter or the CCD surface by yourself.
3. 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 assist-
ance.
4. Replace the protective cover or reattach the sensor unit to the camera immediately after
cleaning.
Cleaning using the HAMA cleaning fluid and tissues
1. Carefully spray the fluid (Hasselblad recommends HAMA Optic Cleaning Fluid 5902) onto
the IR filter at a distance of 10-15 cm (4-5 inches), so that the fluid is applied onto the
filter as a thin, even haze. 1-2 sprays are enough. If you apply too little, the fluid will start
to dry up before you start wiping the filter. As an alternative you can spray the fluid onto
the tissue first, and then apply it to the filter as you wipe it.
2. Now fold the tissue several times to match the width of the IR filter - you may use one or
more tissues at a time if necessary (to give you a better grip). Be completely sure to fold
the paper so that the coated glossy side faces outwards!
!
This is the side to be used to wipe the filter - do not use the other side, as it can do
more damage than good!
3. Gently place the folded tissue onto the edge of the filter using two or three fingers. Apply
firm pressure along the filter’s edge to ensure equal wiping of the entire surface. Sweep
