B meanwhile replies "Off belay" (two jerks), takesoff belay, answers "Climbing" (two jerks), follows A'sroute, climbing no faster than A takes up rope, signaling"Slack" (three jerks) when he wants him to pay out slack,or "Rope" (repeating two jerks) when he takes up ropetoo slowly.
If B is a proficient enough climber, he becomes theleader for the next pitch to be climbed; if not, he assumesA's belay position, and painstakingly avoids snarling therope.
For rope signals the rope must be taut. To signal"Tension," climber places his weight on the rope (or onejerk) and belayer holds; belayer allows rope to run onlyon signal for slack, whereupon he pays out only as much asis pulled in by the climber at that time.
