with over 99.99% eff ective pixels, 0.01% or fewer of the pixels may be
dead, and there may also be spots of black, red, or other colors. This is
not a malfunction. They do not aff ect the images recorded.

If the screen is left on for a prolonged period, screen burn-in may occur
where you see remnants of what was displayed. However, this is only
temporary and will disappear when the camera is left unused for a few
days.

The screen display may seem slightly slow in low temperatures or
may look black in high temperatures. It will return to normal at room
