≥ Colour or brightness of the image may change, or
you may see horizontal bars in the image when the
object is recorded under fluorescent light, mercury
light or sodium light, etc., but this is not a
malfunction.
≥ In motion picture recording mode, record in
intelligent auto mode or set the shutter speed to
1/100 in areas where the power supply frequency is
50 Hz, or 1/125 in areas of 60 Hz.
≥ In still picture recording mode, this will not affect the
recorded image.
≥ Object seems to be warped slightly when the object
moves across the image very fast, but this is
because the unit is using MOS for the image sensor.
This is not a malfunction.
≥ If you take a picture
with the flash in a dark
place or indoors, white
round spots may
appear on the picture
caused by the flash
reflecting of particles of dust in the air. This is not a
malfunction.
A characteristic of this is that the number of round
spots and their position differ in every picture.
≥ The unit has automatically detected an error. Restart
the unit by turning off and on.
≥ The unit will be turned off in about 1 minute if the unit
is not turned off and on.
≥ Repair is needed if it is repeatedly displayed even if
it is restarted. Detach the power connected, and
consult the dealer who you purchased this unit from.
Do not attempt to repair the unit by yourself.
