(2) Setup. When setting up a tripod, you should be sure to place the legs so that you achieve
a stable setup. First, loosen the restraining strap from around the three legs and secure it around one leg.
While standing over the setup mark, grip the tripod with two of the legs close to the body and, by using
one hand, push the third leg out away from the body until it is about 3 feet from the mark. Lower the
tripod until the third leg is on the ground. Place one hand on each of the first two legs and spread them
while taking a short backward step, using the third leg as a pivot point. When the two legs look about as
far away from the mark as the third one and all three are about equally spaced, lower the two legs and
press them into the ground. Make any slight adjustment to level the head further by moving the third leg
a few inches in or out before pressing it into the ground.
