What a novel idea, to actually look up the pertinent instruction.Directly from NPC:
- When not being worn on the uniform and in use, communication devices will be placed at the side of the leg and in appropriate hand when rendering salutes, greetings and other military courtesies/honors.
- The use of an earpiece, blue tooth technology, headsets or hands-free device while in uniform indoors or outdoors is prohibited unless specifically authorized for the execution of official duties (e.g. NSW, security personnel, detailers, etc.).
