≥ Turn off the power to this unit. If the power cannot be turned
off, press the RESET button, or remove the battery or AC
adaptor and then reattach it. Turn on the power again. If
normal operation is still not restored, detach the power
connected, and consult the dealer who you purchased this
unit from.
≥ 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.
