Manual Cleaning
If foreign matter cannot be removed from the low-pass filter
using the “clean image sensor” option (
823), the filter can be
cleaned manually as described below. Note, however, that
because the filter is extremely delicate and easily damaged, we
recommend that manual cleaning be performed only by a
Nikon-authorized service representative.
•
To prevent loss of power during the operation, use a fully-
charged battery or connect an optional AC adapter and power
connector.
•
Manual cleaning requires use of the [
Lock mirror up for
cleaning
] item in the setup menu. The [
Lock mirror up for
cleaning
] item is not available at battery levels of
J
or below
or if the camera is connected to a smart device via Bluetooth
or other devices via USB.
