Nikon D300 User Manual (en)

: When cleaning the camera 
body, use a blower to 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 dry the 
camera thoroughly. In rare 
instances, static electricity may 
cause the LCD displays to light up 
or go dark. This does not indicate a 
malfunction, and the display will 
soon return to normal.
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” (pp. 373, 
376) for information on cleaning 
the low-pass filter.
Lens contacts
: Keep the lens contacts 
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.
: 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 desiccant 
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 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.
