2. Prepare the Lifeline for Descent: Prior to descent, the section of lifeline between the user and the R550 Device
must be tightened to remove any slack. Tighten the lifeline by pulling on the free end of the rope until slack between
the user and R550 Device is removed. Once the lifeline is taut, hold the free end of the lifeline tightly until descent is
initiated.
