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 ( 0 25). If this does not
correct the problem, select single-servo autofocus ( AF-S ;
0

point AF (

0

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 (
