Power Supply
• Use only the special HR-3U rechargeable nickel-metal hydride batteries to
power this camera. Use of any other type of battery is not supported.
• This camera does not have separate batteries for the clock. The date and
time settings of the camera are cleared whenever power is totally cut off
(from both the batteries and AC adaptor). Be sure to reconfigure these
settings after power is interrupted (page 50).
LCD Panel
• The LCD panel is a product of the latest LCD manufacturing technology that
provides a pixel yield of 99.99%. This means that less than 0.01% of the
total pixels are defective (they do not turn on or always remain turned on).
Lens
• You may sometimes notice some distortion in certain types of images, such
as a slight bend in lines that should be straight. This is due to the
characteristics of lens, and does not indicate malfunction of the camera.
