Interestingly, although the procedure in the FCOM has the establish communications part removed in the initial part after donning of the oxygen masks, if you refer to the FCTM, establishing communications with your colleague is still part of the oxygen mask donning procedure, before everything else is illustrated.
Someone once pointed out to me too, "Signs" here refers to both the "Seat Belts" and "No Smoking" switches.
Any thoughts?
