Hi ! I don’t know whether you’re a member at yahoocgms, so I’ll copy my post (on this subject, about two weeks ago) right into here:

They have to SAY that to avoid trouble with the FCC and FAA, but you
shouldn’t actually believe it. Here’s the facts: Other wireless
devices, such as the 802.11 interfaces on PC’s, typically have
transmit power in the range of 20-100 mW (milliWatts). My Dexcom
Transmitter is a maximum of 25 uW (microWatts, that’s a thousand times
LESS). And that’s why PC’s can work 50-250 feet away from their
Wireless Access Points (latter figure is for 802.11n of course), while
our Transmitters and Receivers struggle to exchange data even 15 feet
away. (And sometimes they struggle just 2-3 feet away, if the signal
is going through your body and blankets instead of empty airspace.)
The FAA likes to use rules with “zero tolerance”, rather than fall on
a slippery slope of “how much is REALLY too much”. But in fact, our
TINY transmitters, in the passenger compartment, are totally
irrelevant to the airliner RF environment. Definitely just leave it
in. DO turn off the computer and cellphone, they’re much more powerful.
On a slightly related topic: I always tell TSA that I’m wearing medical devices, and request “hand inspection” for the Dexcom Receiver. (I don’t mention the pump, which has never “bothered” a TSA scanner before. If it ever does set off an alarm, I’ll just say, "Oh yeah, I’m wearing an insulin pump too, but it’s never caused an alarm before…).
This is told to the TSA rep right in front of the scanner at your line, the one who makes sure that all the big shoes are removed and boxed for scanning, along with keys and cellphones and etc. (NOT the “traffic cop” in front, who divides people into different lines.)
In Minimed’s case, you’ve manifestly got an insulin pump-- which inspires a lot less questions than my “mystery electronic thingy” Dexcom. I’d probably just wear a MM right through everything, with no special request to “hand inspect”-- just announce that you’re wearing an insulin pump. But do bring the R/T manual: So that you can show them what the Sensor is if they ask, avoiding a natural inclination on their part to tear it off first, ask questions afterwards. :((( Yeah, that would kinda ruin your flight, half of it lost in “warm up” time while you’re crossing 4 timezones and trying to adjust for the time shift while “blinded”.
The inspectors will be MUCH more comfortable, actually quite relieved, to see that you’ve even brought a manual with matching pictures just for them. Have a GREAT trip! Passengers are fine with a couple off beeps, just look 'em in the eye and say “medical device”.
