 Cleaning and checking the image pickup device
This camera incorporates a dust reduction function to keep dust from getting on the 
image pickup device and to remove any dust or dirt from the image pickup device 
surface with ultrasonic vibrations. The dust reduction function operates when the 
camera is turned on.
The dust reduction function operates at the same time as the pixel mapping, which 
checks the image pickup device and image processing circuitry. Since dust reduction 
is activated every time the camera’s power is turned on, the camera should be held 
upright for the dust reduction function to be effective.
  Pixel Mapping - Checking the image processing functions
The pixel mapping feature allows the camera to check and adjust the image pickup 
device and image processing functions. After using the monitor or taking continuous 
shots, wait for at least one minute before using the pixel mapping function to ensure 
that it operates correctly.
