is also acceptable, if available on your camera.

Make sure your camera is set to "Manual Focus" mode.

Make sure your camera is set to "Manual Exposure" mode.

If you enabled "Long Exposure Noise Reduction" setting on your camera, make sure Promote Control has

its LeNR setting set to "On". Promote Control will try to match those settings for you, but if this

attempt fails, an error may be shown.

Make sure that the "Mirror Lock-Up" (MLU) settings on your camera and Promote Control are matched -

both need to be either "On" or "Off". Promote Control will try to match those settings for you, but if this

attempt fails, an error may be shown.

9.3.5 Camera cannot be recognized

The device connected to the Promote Control USB port is using an unknown, non-camera protocol or is

the "Mid Exposure" setting to continue.
