•Continuing to charge the battery af ter it is fully charged can impair 
battery 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-EL15 battery.
• The supplied power cable and AC wall adapter are for use with the 
MH-25a only.
 Use the charger with compatible batteries only. Unplug 
when not in use.
• Charge the battery before use.
 When taking photographs on 
important occasions, ready a spare battery and keep it fully charged. Depending on your location, it may be difficult to purchase 
replacement 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 an d 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 
regulations.

in the following graph:
The maximum and minimum values for EV vary with ISO 
sensitivity; the above graph assu mes an ISO sensitivity of ISO 
100 equivalent.
 When matrix metering is used, values over 
16 1/3EV are reduced to 16 1/3EV.

If the camera fails to function as expected, check the list of 
common problems below before consulting your retailer or 
Nikon-authorized service representative.
Battery/Display
Troubleshooting
The camera is on but does not respond: Wait for recording to end. If the 
problem persists, turn the camera off. If the camera does not turn off, 
remove and reinsert the battery or, if you are using an AC adapter, 
disconnect and reconnect the AC adapter.
 Note that although any data 
currently being recorded will be lost, data that have already been 
recorded will not be affected by removing or disconnecting the power 
source.
Viewfinder is out of focus : Adjust viewfinder focus ( 017).
 If this does not 
correct the problem, select single-servo AF ( AF-S; 0 87), single-point AF 
( 0 90), and the center focus point ( 094), and then frame a high-
contrast subject in the center focus point and press the shutter-release 
button halfway to focus the camera.
 With the camera in focus, use the 
diopter adjustment control to bring the subject into clear focus in the 
viewfinder.
 If necessary, viewfinder focus can be further adjusted using 
optional corrective lenses ( 0438).
Viewfinder is dark : Insert a fully-charged battery ( 013, 19).
Displays turn off without warning : Choose longer delays for Custom Setting 
c2 ( Standby timer ) or c4 (Monitor off delay ) (0 319, 320).

Live view ends unexpectedly or does not start: Live view may end automatically 
to prevent damage to the camera’s internal circuits if:
• The ambient temperature is high 
• The camera has been used for extended periods in live view or to 
record movies 
• The camera has been used in continuous release modes for extended 
periods
If live view does not start when you press the  a button, wait for the 
internal circuits to cool and then try again.
 Note that the camera may 
feel warm to the touch, but this does not indicate a malfunction.
Image artifacts appear during live view : The temperature of the camera’s 
internal circuits may rise during live view, causing image “noise” in the 
form of bright spots, randomly-spaced br ight pixels, or fog. Exit live view

other light source with brief duration was used during live view or movie 
recording.
Noise (bright spots, randomly-spaced bright pi xels, fog, lines, or reddish areas) appears 
in photos :
• To reduce randomly-spaced bright pi xels, fog, or lines, choose lower 
ISO sensitivity or use high ISO noise reduction ( 0109, 299).
• To reduce bright spots, randomly-spaced bright pixels, or fog at shutter 
speeds slower than 1 s or to reduce  reddish areas and other artifacts in 
long time-exposures, enable long exposure noise reduction ( 0299).
