• A 4700 system with 12 mm minimum object resolution and two channels disabled has a minimum object
sensitivity of:
12 mm + 6.25 mm + 6.25 mm = 24.5 mm (0.96 inches).
If the size of the object detected by the 4700 system increases, the minimum safe distance must
increase. Use the minimum object sensitivity given in T
able 5-5, Table 5-6, Table 5-7 & Table 5-8 to
determine the new figure to use when computing the safety distance.
