SUBJ: FRONT VOICEMITTER RING MCU-2/P SERIES GAS MASK.
1. THE FRONT VOICEMITTER RING ON THE MCU-2/P SERIES GAS MASK IS TO ONLY BE CHECKED FOR TIGHTNESS USING THE TIPS OF TWO FINGERS AS STATED IN TABLE 5-1 OF T.O. 14P4-15-1. "DO NOT" REPEAT "DO NOT"ATTEMPT TO LOOSEN THE RETAINING RING. THIS WILL CAUSE THE MASK TO LEAK WHEN SUBJECTED TO THE NEGATIVE PRESSURES OF BREATHING THROUGH THE C-2 CANISTER.
2. DO NOT DEVISE YOUR OWN INSPECTION METHODS. IF YOU FEEL THAT THE TECHNICAL ORDER IS DEFICIENT, SUBMIT YOUR RECOMMENDED CHANGE ON AN AFTO FORM 22 FOR EVALUATION. TAMPERING WITH THE RETAINING RING WOULD DEGRADATE THE CHEMICAL WARFARE CAPABILITY.
