Do not touch the shutter curtain:
The shutter curtain is extremely thin and easily damaged. Under
no circumstances should you exert pressure on the curtain, poke it with cleaning tools, or
subject it to powerful air currents from a blower. These actions could scratch, deform, or tear
the curtain.
Storage:
To prevent mold or mildew, store the camera in a dry, well-ventilated area. If you are
using an AC adapter, unplug the adapter to prevent fire. If the product will not be used for an
extended period, remove the battery to prevent leakage and store the camera in a plastic bag
containing a desiccant. Do not, hO'vvever, store the camera case in a plastic bag, as this may
cause the material to deteriorate. Note that desiccant gradually loses its capacity to absorb
moisture and should be replaced at regular intervals.
To prevent mold or mi!de\N, take the camera out of storage at least once a month. Turn the
camera on and release the shutter a few times before putting it away.
Store the battery in a cool, dry place. Replace the terminal cover before putting the battery
away.
Notes on the monitor:
The monitor may contain a few pixels that are always lit or that do not light.
This is common to all TFT LCD monitors and does not indicate a malfunction. Images recorded
with the product are unaffected.
Images in the monitor may be difficult to see in a bright light.
Do not apply pressure to the monitor, as this could cause damage or malfunction. Dust or lint
on the monitor can be removed with a blower. Stains can be removed by wiping lightly with a
soft cloth or chamois leather. Should the monitor break, care should be taken to avoid injury
from broken glass and to prevent liquid crystal from the monitor touching the skin or entering
the eyes and mouth.
Moire:
Moire is an interference pattern created by the interaction of an image containing a
regular, repeating grid, such as the pattern of weave in cloth or windows in a building, with the
camera image sensor grid. If you notice moire in your photographs, try changing the distance
to the subject, zooming in and out, or changing the angle between the subject and the
camera.
