•Continuing to charge the battery after it is fully charged can impair bat- tery performance.

•A marked drop in the time a fully charged battery retains its charge when used at room temperature indicates that it requires replacement. Purchase a new EN-EL20a battery.

•Charge the battery before use. When taking photographs on important occasions, ready a spare EN-EL20a battery and keep it fully charged. Depending on your location, it may be difficult to purchase replace- ment batteries on short notice. Note that on cold days, the capacity of batteries tends to decrease. Be sure the battery is fully charged before taking photographs outside in cold weather. Keep a spare battery in a warm place and exchange the two as necessary. Once warmed, a cold battery may recover some of its charge.

•Used batteries are a valuable resource; recycle in accord with local reg- ulations.

DServicing the Camera and Accessories

The camera is a precision device and requires regular servicing. Nikon recommends that the camera be inspected by the original retailer or Nikon-authorized service representative once every one to two years, and that it be serviced once every three to five years (note that fees apply to these services). Frequent inspection and servicing are particularly recommended if the camera is used professionally. Any accessories regularly used with the camera, such as lenses, should be included when the camera is inspected or serviced.
