Caring for the Camera and Battery: Cautions

The product may malfunction if sub ject ed to 
strong shocks or vi bra tion.
Keep dry
This product is not waterproof, and may 
mal func tion if im 
mersed in wa 
ter or ex-
 posed to high levels of hu mid i ty.  Rust ing 
of the in ter nal mech a nism can cause ir rep a-
 ra ble dam age.
Avoid sudden changes in tem per a ture
Sud den chang 
es in tem 
per a ture, such as 
oc cur when en 
ter ing or leav 
ing a heat 
ed 
build ing on a cold day, can cause con den -
sa tion in side the de vice.  To prevent con den -
sa tion, place the device in a car ry ing case or 
a plas tic bag be fore ex pos ing it to sud den 
chang es in tem per a ture.
Keep away from strong mag net ic fi elds
Do not use or store this device in the vi cin i ty 
of equip 
ment that gen 
er ates strong elec-
 tro mag net ic radiation or mag 
net ic fi elds.  
Strong static charg es or the mag net ic fi elds 
pro duced by equip ment such as radio trans-
 mit ters could in 
ter fere with the monitor, 
dam age data stored on the mem o ry card, or 
affect the prod uct’s in ter nal cir cuit ry.
Do not leave the lens pointed at the sun
Do not leave the lens pointed at the sun or 
another sight source for an extended period.  
Intense light may cause the image sensor to 
deteriorate or produce a white blur effect in 
photographs.
Blooming
Vertical white streaks may appear in pho-
tographs of the sun or other strong light 
sources.  This phenomenon, known as 
“blooming,” can be prevented by reducing 
the amount of light that falls on the image 
sensor, either by choosing a slow shutter 
speed and small aperture or by using an 
ND fi lter. 
Do not touch the shutter curtain
The shutter curtain is extremely thin and 
easily damaged.  Under no cir 
cum stanc es 
should you exert pres 
sure on the curtain, 
poke it with clean ing tools, or sub ject it to 
powerful air cur rents from a blow er.  These 
actions could scratch, de form, or tear the 
curtain.
Handle all mov ing parts with care
Do not ap ply force to the bat tery-cham ber, 
card-slot, or con nec tor cov ers.  These parts 
are es pe cial ly sus cep ti ble to dam age.
Cleaning
• When cleaning the camera body, use a 
blow er to remove dust and lint, then wipe 
gently with a soft, dry cloth.  After using 
your camera at the beach or seaside, wipe 
off any sand or salt using a cloth lightly 
damp ened with pure water and then dry 
your camera thoroughly.  In rare in stanc es, 
static electricity produced by a brush or 
cloth may cause the LCD dis plays to light 
up or dark en.  This does not in di cate a 
malfunction, and the dis play will shortly 
return to normal.
• When cleaning the lens and mirror, re-
 mem ber that these elements are easily 
dam aged.  Dust and lint should be gen tly 
removed with a blower.  When using an 
aerosol blower, keep the can vertical (tilt-
ing the can could result in liquid be 
ing 
sprayed on the mir ror).  If you do get a 
fi ngerprint or other stain on the lens, ap-
ply a small amount of lens cleaner to a 
soft cloth and wipe the lens carefully.
• See “Cleaning the Low-Pass Filter” for in-
formation on cleaning the low-pass fi lter 
(

Storage
• To prevent mold or mildew, store the cam-
 era in a dry, well-ven ti lat ed area.  If you will 
not be us ing the prod uct for long pe ri ods, 
re move the bat tery to pre vent leak age and 
store the cam era in a plastic bag con tain ing
