Dust that could not be removed by automatic cleaning can be removed manually with a commercially available blower or similar tool.

  2. Select [OK].

  3. Remove the lens and clean the sensor.

  4. End the cleaning.

  • Using the household power outlet accessories (sold separately) is recommended.


  • While cleaning the sensor, never do any of the following. If the power is cut off, the shutter will close. These may result in damaging the image sensor and shutter curtains.

    • Setting the power switch to Power off.
    • Removing or inserting the battery.
  • The surface of the image sensor is extremely delicate. Clean the sensor with care.
  • Use a plain blower without any brush attached. A brush can scratch the sensor.
  • Do not insert the blower tip inside the camera beyond the lens mount. If the power is turned off, the shutter will close and the shutter curtains may get damaged.
  • Never use pressurized air or gas to clean the sensor. Pressurized air may damage the sensor, and sprayed gas may freeze on the sensor and scratch it.
