Cleaning The Cmos Sensor - Canon EOS 5D Instruction Manual

Cleaning the CMOS sensor*
The image sensor is like the film in a film camera. If any dust adheres
on the image sensor, it may show up as a dark speck on the images. To
avoid this, follow the procedure below to clean the image sensor.
Using the AC Adapter Kit ACK-E2 (optional, see page 166) is
recommended. If you use a battery, make sure the battery level is
sufficient.
Install the DC Coupler
(p.26)
or a
battery and turn the
<~>
switch
to
<ON>.
Select [Sensor cleaning].
Turn the
<

dial to select
[tT
Sensor cleaning], then press
<

>.
If you are using a battery with
sufficient power, the screen shown in
step 3 will appear.
If the battery is exhausted, a warning
message will appear and you will not
be able to proceed further. Either
recharge the battery or use a DC
coupler and start from step 1 again.
Select [OK].
Turn the
<

then press <§>.
The mirror will lock up and the shutter
