Caring for the Camera and Battery: Cautions
Do not drop: The product may malfunction if subjected to Cleaning:When cleaning tile camera body, use a blower to
strong shocks or vibration
Keepdry: This product is not waterproof, and may malfunc
tion if immersed in water or exposed to high levels of
humidity Rusting of the internal mechanism can cause
irreparable damage
Avoidsuddenchanges in temperature: Sudden changes in tern
perature, such as occur when entering or leaving a heated
building on a cold day, can cause condensation inside the
device To prevent condensation, place the device in a car
rying case or plastic bag before exposing it to sudden
changes in temperature
Keepawayfrom strongmagnetic fields: Do not use or store this
devk:e in the vicinity of equipment that generates strong
electromagnetic radiation or magnetic fields Strong static
charges or the magnetic fields produced by equipment
such as radio transmitters could interfere with the monitor,
damage data stored on the memory card, or affect the
product's internal circuitry
De not leave the lens pointed at the sun: Do not leave the lens
pointed at the sun or other strong light source for an
extended period Intense light may cause the image sensor
to deteriorate or produce a white blur effect in photo
graphs
Blooming:Vertical white streaks may appear in photographs
of the sun or other strong light sources This phenomenon,
known as "blooming/' can be prevented by reducing the
amount of light that fails on the image sensor, either by
choosing a slow shutter speed and small aperture or by
using an ND filter
Do not touch the shutter curtain: The shutter curtain is
extremely thin and easily damaged. Under no circum
stances 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
Handle all movingparts with care: Do not apply force to the bat
tery chamber, card slot, or connector covers These parts
are especially susceptible to damage
Lensc0utacts: Keep the lens contacts clean
Turn the product off before removingor disconnecting the power
source:Do not unplug ff/e product or remove the battery
while the product is on or while images are being recorded
or deleted Forcibly cutting power in these circumstances
could result in loss of data or in damage to product memory
or internal circuitry To prevent an accidental interruption of
power, avoid carrying the product from one location to
another while the AC adapter is connected
gently remove dust and lint, then wipe gently with a soft,
dry cloth After using the camera at the beach or seaside,
wipe off any sand or salt using a cloth lightly dampened in
pure water and then @y the camera thoroughly
The lens and mirror are easily damaged Dust and lint
should be gently removed with a blower When using an
aerosol blower, keep the can vertical to prevent discharge of
liquid To remove fingerprints and other stains from the
lens, apply a small amount of lens cleaner to a soft cloth and
wipe the lens carefully
See "The Low Pass Filter" (!@ 105) for information on clean
ing the low pass filter
Storage:To prevent mold or mildew, store the camera in a
dry, well ventilated area 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, however, store the camera case in a plastic bag, as
this may cause the material to deteriorate Note that desi
cant gradually loses its capacity to absorb moisture and
should be replaced at regular intervals
To prevent mold or mildew, take the camera out of storage
at least once a month Turn the amera 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
Noteson the monitor: The monitor may contain a few pixels
that are always lit or that do not light This is common to all
TFT LdD 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 mon
itor break, care should be taken to avoid injury from broken
glass and to prevent liquid crystal from the monitor touch
ing the skin or entering the eyes and mouth
Batteries:Dirt on the battery terminals can prevent the cam
era from functioning and should be removed with a soft,
dry cloth before use After removing the battery from the
camera, be sure to replace the terminal cover
Charge the battery before use. When taking photographs
on important occasions, ready a spare EN EL9 battery and
keep it fully charged Depending on your location, it may be
difficult to purchase replacement batteries on short notice
