Lock Mirror Up For Cleaning - Nikon D850 Menu Manual

Lock Mirror up for Cleaning

Use this option to lock the mirror up so that dust that cannot be
removed using Clean image sensor can be removed manually.
Note, however, that the sensor is extremely delicate and easily
damaged, we recommend that manual cleaning be performed
only by a Nikon-authorized service representative.
❚❚ Manual Cleaning
The sensor can be cleaned manually as described below.
1
Charge the battery or connect an AC adapter.
A reliable power source is required when inspecting or
cleaning the image sensor. Turn the camera off and insert a
fully-charged battery or connect an optional AC adapter and
power connector. The Lock mirror up for cleaning option is
only available in the setup menu if the battery level is over
J and the camera is not connected to a smart device via
Bluetooth or other devices via USB.
