Dust that could not be removed by the automatic sensor cleaning can
be removed manually with a commercially-available blower, etc. Before
cleaning the sensor, detach the lens from the camera.
The image sensor is extremely delicate. If the sensor needs to be
cleaned directly, having it done by a Canon Service Center is
recommended.
If you will clean the sensor manually, make sure to use a fully-charged
battery.
Using the household power outlet accessories (sold separately, p.530) is
recommended.
