Acquire dust off reference data.
Press the shutter-release button the rest of the way down to acquire Image Dust 
Off reference data. The monitor turns off when the shutter-release button is 
pressed. Note that noise reduction will be performed if the subject is poorly lit, 
increasing recording times.
If the reference object is too bright or too dark, the camera 
may be unable to acquire Image Dust Off reference data 
and the message shown at right will be displayed. Choose 
another reference object and repeat the process from 
step 1.
Reduce flicker and banding when shooting under fluorescent or mercury-vapor 
lighting during live view or movie recording. Choose Auto to allow the camera to 
automatically choose the correct frequency, or manually match the frequency to that 
of the local AC power supply.

Image Sensor Cleaning
Dust off reference data recorded before image sensor cleaning is performed can not be used 
with photographs taken after image sensor cleaning is performed. Select Clean sensor and 
then start
 only if the dust off reference data will not be used with existing photographs.

Image Dust Off Reference Data
The same reference data can be used for photographs taken with 
different lenses or at different apertures. Reference images can not 
be viewed using computer imaging software. A grid pattern is 
displayed when reference images are viewed on the camera.

Flicker Reduction
If Auto fails to produce the desired results and you are unsure as to the frequency of the local 
power supply, test both the 50 and 60 Hz options and choose the one that produces the best 
results. Flicker reduction may not produce the desired results if the subject is very bright, in 
which case you should try choosing a smaller aperture (higher f-number).
