Nikon COOLPIX 900 User Manual page 37

Once the camera has been connected to your computer, you can use Nikon
View to browse the contents of the camera's memory or to copy items from
the camera to disk.
Note: When unplugging the cable from the camera, pull the cable from
the camera while pushing the cable's release button (located on the
underside of the connector). Unplug the cable by the connector, not by
pulling directly on the cable itself.
Caution: Do not use the camera with a computer when battery power
is low or critical. If the battery indicator in the control panel shows low or
critical when the camera is connected to a computer, wait for the data
transfer icon to stop flashing, then disconnect the camera and replace the
batteries.
