SKIP FEATURE:
Items 36 – 38 embody a feature that allows the user to define a Fire Zone the C-More will avoid. In
the rare instance when a unit emits an objectionable noise at a certain Fire Rate and no other
remedy solves the problem, a Fire Rate skip zone may be defined to command the C-More to Skip-
Over the defined Fire Rate.
