SAFETY
Miss-sequencing: Prevents arming the fuze whenever arming
condition of “air flow” precedes arming condition
of “set back”.
Arming distance: 70m minimum from muzzle.
Double loading: The fuze will not function in bore in at double
loading event.
Shorted electric
detonator:
The electric detonator is shortened until arming.
Safety pull wire: No use of safety pull wire.
