Conditions
The camera gets hot.
The lens clicks.
The clock setting is
reset.
Strange colors appear
around the edge of the
image.
File numbers are not
created in order.
The file numbers are
recorded in ascending
order.
Others
The camera may get a little warm while you are using it, but
this is normal.
When brightness has changed due to the zoom or the
movement of the camera or other, the lens may click and the
picture on the screen may be drastically changed, however,
the pictures are not affected.
The sound is caused by automatic adjustment of the
aperture. It is not a malfunction.
If you do not use the camera for a long time, the clock setting
may be reset. When the message [PLEASE SET THE
CLOCK] appears, set the clock again. (P20)
When you take a picture before setting the clock, [0:00 0. 0.
0] is recorded.
Depending on the zoom magnification, the picture may have
some colored fringes around the subject. This is called
chromatic aberration and may be more visible when recording
distant subjects. However this is not a malfunction.
Certain operations cause pictures to be saved in folders with
different numbers. (P108)
If the battery is inserted or removed when the camera is not
turned off, the recorded folder numbers are lost.
However if you turn the camera on again and record pictures,
the recorded folder numbers are different from the prior
recorded folder numbers.
