The standard bayonet receivers are individually fitted to the aircrew member. Before you
install the receivers, you must ensure that the helmet has been properly fitted as described in
Paragraphs 2-2.1, 2-2.2, and, 2-2.3. You will also familiarize the aircrew member with mask
attachment in this procedure.

and ensure that you
have the following components of the
standard bayonet receiver kit:

NOTE:
If the aircrew member has
worn the oxygen mask with a helmet
other than the one being fitted with
receiver assemblies, check the mask
