Paranormal gear becoming disabled in-use is a well-known phenomenon; it's happened to me. The gear then works perfectly once removed from the offending environment.
I'm sure any sufficiently advanced life form has mastered the physics behind it, and be able to do it to hardened military electronics as well. It's probably fairly easy for those who can at will manipulate matter, energy, and the dimensional constraints that we must currently deal with. It's pretty obvious they have work-arounds for everyday Newtonian physics and are not hampered by our limitations.
