Canon eos 350d digital rebel xt User Manual

The image sensor is like the ﬁlm in a ﬁlm camera.If any dust or other
foreign matter adheres to the image sensor, it may show up as a dark
speck in the images. To avoid this, follow the procedure below to clean
the image sensor. Note that the image sensor is a very delicate
component. If possible, you should have it cleaned by a Canon Service
Center.
While you clean the image sensor, the camera must be turned on.
Using the AC Adapter Kit ACK-DC20 (optional, see page 158) is
recommended. If you use a battery, make sure the battery level is
sufﬁcient. Before cleaning the sensor, detach the lens from the camera.
