perimeter to keep out dust.
＊ Absorbent material: This is industrial-grade, double-sided tape. It does not lose its stickiness even after alot of
dust adheres to it.
Also, compared to a rival manufacturer's dust-removal system which uses a vibrating
glass, the EOS D REBEL XTI / EOS 400D D uses low-pass filter 1 which vibrates directly
to shake off dust. Therefore, the optical performance is not degraded by an extra sheet of
glass, and compactness is maintained. The camera body size is still the same as the EOS
KISS DIGITAL N.
⑵Unit operation timing
①Auto
The default setting has the self-cleaning unit
operating for 1 sec. when the camera's power switch
is turned on or off. During the self-cleaning operation,
the LCD monitor displays the self-cleaning system
logo. (Fig. 006 and 007)
②Manual
The self-cleaning system can also be activated
manually with the menu. Note that shooting priority
still takes effect. If you press the shutter button
halfway or press the menu button during the self-
cleaning operation (in either the Auto or Manual
modes), the cleaning operation will stop and the
camera will be ready to shoot.
③Off
If you use the Dust Delete Data feature and do not
want to change the data of the dust coordinates, you
can disable the self-cleaning operation so it does not
operate when the power is tuned on or off.
⑶Power consumption
Since the self-cleaning system is powered by an
extremely low amount of power, it hardly affects the
number of possible shots with the battery.
●Disabling the self-cleaning unit
To prevent the piezoelectric element from
overheating, the self-cleaning unit cannot operate for
3 sec. after any operation. Also, if the self-cleaning
unit is operated five consecutive times within 10 sec.,
it will not work for 10 sec. afterward.
While the self-cleaning unit is disabled, if you select
[Sensor cleaning: Auto], the [Clean now] option will be
grayed out and cannot be selected. (Fig. 008)
