Narrative:
On oct/mon/00, at XA30 pm, I was informed that I was scheduled for a maintenance meeting because of a non-compliance dated around oct/sat/00. According to this non-compliance I was improperly storing cockpit portable oxygen bottles. The air carrier general procedures manual states that the bottle and mask must be bagged together. Now, air carrier's general maintenance manual and also air carrier maintenance manual states when removing oxygen bottles (portable) the bag nor the mask needs to be bagged, to the best of my knowledge. I feel to the best of my knowledge, I followed proper paperwork.
