All I can say to you gents is that you must wear it 85% of your life... If there's an outlet in the CRC, I suppose you could use it there as well if needed.
A few things happen in the CRC that we do not speak about, but from our esteemed manuals :
"Units must not be connected to any of the aircraft power sockets"
As long as you do not do a Honeyball Lecter on me in the CRC, feel free to wear it........
