Cleaning The Cmos Sensor - Canon EOS 30D 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 26, 184) is
I
recommended. If you use a battery, make sure the battery level is
sufficient. Before cleaning the sensor, detach the lens from the camera.
Install the DC Coupler
(p.26)
or a
battery and turn the <
~
> switch
to
<ON>.
Select [Sensor cleaning].
Turn the <
0
>
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
<0>
dial to select [OK],
then press
<
§
>.
In a moment, the mirror will lockup
and the shutter will open.
"CLEA n" will blink on the LCD panel.
