close and it may damage the shutter curtains and image sensor.

• Opening the battery compartment cover.
¡ Do not insert the blower tip inside the camera beyond the lens mount. If
the power goes out, the shutter will close and the shutter curtains and
image sensor may be damaged.
¡ Use a blower not attached with a brush. A brush can scratch the sensor.

to the camera and size-AA batteries supply the power. Use AC Adapter
Kit ACK-DC20 (optional) or use a battery having sufficient power.
