As with any method of communicating with the subconscious mind, we must have belief that the method will work. What makes communication with the subconscious work is the expectation and the realization. Your subconscious mind will not cooperate with you if you do not believe you can communicate with it. Having said that - proceed as follows:

Read the instructions so your mind knows what is expected of it. Put the target so the YES line is vertical. Then, hold the pendulum at the center of the “crosshairs” just above the surface of the paper while permitting as much of the full length of the thread to be extended. keep the crystal just above the paper. Give the pendulum a “warm up” exercise by asking the pendulum to go in circles.
(In this exercise and all others, make no conscious effort to affect the movement of the pendulum, let your subconscious mind move it without your conscious help). This is the classic ideomotor response.

The lines on the target are marked “Yes” and "No”. Test the validity of the lines with your own mind’s orientation. Place the “yes” line in a vertical orientation. (If you were to move your head up and down in a yes response it would be in this same orientation.) Having done this, ask the pendulum if your name is.... (use your name). If the pendulum goes in the direction of the “yes” line, you may assume that this will always be a “yes” answer. If it goes in the “no” direction, simply turn the paper 90 degrees so the “yes” line matches the answer your mind gave you for yes. Most minds respond to the normal “up/down” head movement for yes or no, but some don’t, that is why we must establish the “Yes” line orientation. 

Note: The response may not be immediate (especially in the beginning). Be patient and give it a little time to respond. If you want to ask another question and the pendulum is still swinging, lower it to the paper to stop the movement and then raise it again and ask the question. By the way, you do not need a target to perform this communication, once you have established the 'rules' the pendulum alone can be used. Now that we have worked out the yes/no orientation, there are other considerations. When your subconscious doesn’t know the answer, the pendulum will go in circles or move aimlessly around. You may have to rephrase the question, or ask a different question. If the subconscious does not want to answer at this time, it will move in a diagonal motion. It may want to protect you from a unpleasant situation or may not want you to know at this time).

One caveat: Do not ask dumb questions to which it cannot know the answer! For example: “Is my husband faithful to me?”. Also understand that your mind, under some conditions, may not know the answer to the question, but will try to please you by giving the answer that you want to hear. For example: “No”, to the previous question. Now this can cause more than a few problems to an otherwise exemplary marriage. (By the way, this example actually happened and required a great deal of explaining by the hapless husband).
