Problems and Solutions
Solutions to some common issues are listed below.
Battery/Display
● The camera is on but does not respond:
Wait for recording and other operations to end.
If the problem persists, turn the camera off.
If the camera does not turn off, remove and reinsert the battery.
If you are using an AC adapter, disconnect and reconnect the AC adapter.
- Any data currently being recorded will be lost.
- Data that have already been recorded are not affected by removing or disconnecting the
power source.
● The viewfinder or monitor does not turn on:
Have you changed the monitor mode? Choose a different monitor mode using the M button.
Have you limited the choice of monitor modes available using the [Limit monitor mode
selection] item in the setup menu? Adjust settings as required.
Dust, lint, or other foreign matter on the eye sensor may prevent it functioning normally. Clean
the eye sensor with a blower.
● The viewfinder is out of focus:
Rotate the diopter adjustment control to adjust viewfinder focus.
If adjusting viewfinder focus does not correct the problem, set the focus mode to AF‑S and the
AF-area mode to single-point AF. Next, select the center focus point, choose a high-contrast
subject, and focus using autofocus. With the camera in focus, use the diopter adjustment control
to bring the subject into clear focus in the viewfinder.
