2. Mount the camera on a tripod (recommended) or place the camera on a stable, level surface.
3. Press the button and rotate main command dial until (delayed remote) or (quick response remote) is displayed in the control panel.
4. Aim the transmitter on the remote control at the infrared receiver on the camera (usually within +/- 30 degree of the lens axis, from the left to the right and from the top to the bottom) and press the shutter-release button on the remote control (when using the remote outdoors, make sure that the subject is not backlit and that the line of site between the transmitter and the infrared receiver is not blocked by the lens or other obstacles ).
5. How the camera focuses and shoots depends on the option selected for your camera's custom setting. For further information, check your camera's manual.
