ML-L3 Remote Control for Nikon D90?
I have it but how do I set it up on my camera
Simple. To the right of the upper window of the screen is a little button with what looks like sheets of paper in it. Press and turn the rear wheel. Look at the screen. When you get to the icon that looks like a battery or something and the stopping distance there. Now trigger when you press the button on the remote. But make sure you are in front of the camera and pointing the sensor. The camera needs to read the log in order to fire.
