Today Nikon released a new C firmware update version 1.31 for the Nikon D4s camera that contains a single fix for the WR-R10 wireless remote controller:
Fixed an issue that occurred with WR-R10 wireless remote controller firmware version 3.00. In rare cases, the camera would fail to display the number of exposures remaining or would take about a minute to power down when the WR-R10 was connected.
