The CA-3 Remote Shutter Release for GR Series and Theta S Cameras from Ricoh works when connected to a compatible camera by way of the USB cable originally bundled with the camera. The shutter button is located at the top of the device, which enables the user to operate the camera shutter. The device can be turned on and off, and it is powered by a single AAA battery.
The half-press shutter function does not apply to the Ricoh Theta S camera.
