Bulletin Subject: 
Communication Module used on Kirby Morgan® Helmets & EXO® Masks P/N 320-025
Products Affected: 
305-020, 315-201, 315-206, 315-210, 315-215, 320-023, 320-024, 515-023, 515-024, 520-130, 520-131, 520-132.

The communication mount nut (320-026) should never be tightened using a spanner or other
tool. Tightening the mount nut using a tool will add excessive strain to the parts and could cause damage to the module allowing the module to break free, resulting in flooding of the helmet which could cause injury, or drowning.

Wrenches or tools should not be used to tighten the module communication mount nut. The mount nut should be installed and tightened by hand only.
