Cleaning using the HAMA cleaning fluid and tissues
Note! Hasselblad recommends HAMA Optic Cleaning Fluid 5902.
1. Carefully spray the fluid 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. Fold the tissue several times to match the width of the IR filter–you might use two
or three tissues at a time if necessary (to give you a better grip). Be sure to fold the
paper so that the coated glossy side faces outwards–do not use the other side, as it
can do more harm than good!
3. Gently place the folded tissue onto the edge of the filter using two or three fingers.
Be sure to wipe the entire surface evenly. Sweep the filter only once. Do not wipe the
same area twice with the same tissue as you might reapply dirt removed in the first
sweep.
4. Finally check if the IR filter has been properly cleaned either by visual inspection or
by mounting the sensor unit to the camera and making a shot. If further cleaning is
needed, repeat cleaning procedure.
Cleaning with an E-Wipe
E-wipes are individually packed wet tissues.
1. Tear at the notch to break seal.
2. Remove e-wipe from its packaging and continue without delay.
3. Fold the tissue to match the width of the IR filter.
4. Apply firm pressure using two or three fingers at the edge of the wipe to ensure an
even, firm contact with filter surface. Wipe the surface in one unbroken motion.
5. Finally check if the IR filter has been properly cleaned either by visual inspection or
by mounting the sensor unit to the camera and making a shot. If further cleaning is
needed, repeat cleaning procedure.
Attaching the sensor unit
Position the sensor unit retention groove onto the sensor unit support on the camera
body ensuring that they are correctly positioned. Swing the sensor unit towards the
camera body and firmly press into place with a click. If there is resistance, the magazine
retaining catch on the camera has probably been inadvertently released. In that case,
push the release button again to reset the catch.
Cleaning the housings
If the camera becomes dirty, clean it with a soft, clean cloth lightly moistened with water
only. Do not use any other solvents and do not allow water to seep in the openings.
N o t e
Do not use same side of the e-wipe
twice as you will be likely to re apply
any particles removed in the first
pass.
