A Notes on the Monitor
• The monitor may contain a few pixels that are always lit or that do not light. This is char-
acteristic of all TFT LCD displays and does not indicate a malfunction. Images recorded
using the product will not be affected.
• When you frame bright subjects, vertical, red, comet-like streaks that brighten toward
either end may appear in the display. This phenomenon, known as “smear,” does not
appear in the final photograph and does not indicate a malfunction. Some smear may
appear in movies.
• Images in the monitor may be difficult to see in a bright light.
• The monitor is lit by an LED backlight. Should the monitor begin to dim or flicker, con-
tact a Nikon-authorized service representative.
A Batteries
• Check the battery level when taking the camera out and charge the battery if necessary
(B 16). Do not continue charging once the battery is fully charged, as this will result in
reduced battery performance. If possible, carry a fully-charged spare battery when tak-
ing pictures on important occasions.
• Do not use the battery at ambient temperatures below 0°C (32°F) or above 40°C (104°F).
During charging, the temperature should be in the vicinity of 5–35°C (41–95°F). Note
that the battery may become hot during use; wait for the battery to cool before
charging. Failure to observe these precautions could damage the battery, impair its
performance, or prevent it from charging normally.
• On cold days, the capacity of batteries tends to decrease. Be sure that the battery is fully
charged before heading outside to take pictures in cold weather. Keep spare batteries in
a warm place and exchange as necessary. Once warmed, a cold battery may recover
some of its charge.
• Dirt on the battery terminals can prevent the camera from functioning.
• When the battery is not in use, remove it from the camera or battery charger and replace
the terminal cover. The camera and battery charger draw minute amounts of current
even when off; if left in place, the battery could be drained to the point that it no longer
functions. Turning the camera on or off while the battery is exhausted can result in
reduced battery life. If the battery will not be used for an extended period, store it in a
cool (15°C–25°C/59°F–77°F), dry place. Recharge it at least once a year and run it flat
before returning it to storage.
• Replace the battery when it no longer holds a charge. Used batteries are a valuable
resource. Please recycle used batteries in accordance with local regulations.
