You can never be paranoid enough.
What your looking for is a tempest enclosure.
Its basically a Faraday cage but tested to NATO et al
standards.(https://en.wikipedia.org/wiki/Tempest_(codename)).
A bunch of years ago I was dealing with CSE and got to learn that you
can read a CRT screen from a good distance away (I vaguely remember it
was on the order of a KM or so). There is apparently at least 1 tempest
building in Ottawa that got screwed up because someone cut some holes
for plumbing.
So your not the first person worried about others capturing your
radiated signal.
Not that long ago I read an ACM article talking about being able to read
an LCD screen in the next room from RF and then there was another ACM
article about being able to read a screen from the reflection off a
persons eyeballs.
So to keep completely safe.
1) remove the battery
2) wrap it in aluminum foil
3) wrap it in copper foil
4) solder the edges.

A Faraday cage is enough. Put the machine inside a grounded metallic
box, and you are good to go.
Opening the machine and removing the wireless modules, or cutting
traces giving power to the wireless module would be more permanent,
but a Faraday cage is faster to deploy and "undeploy."

Greetings
Many companies are now developing equipment for home use that is
for the latest
buzz in the world - - IoT (more morons them!).
There is, as a result, the need to be searching for a cell phone
signal (a wireless section that can only be put in airplane mode
not an off). This machine behavior has me very concerned about my
personal information security.
Any suggestions on how to 'shut off' wireless services on a
machine that doesn't really have too much in the way for access?
(Only access that I can see is through the memory card but that
only has data loaded no system information - - - no other visible
ports. Any ideas for hacks to disable this wireless module will be
gratefully accepted. (I do need the machine to work though so no -
- - sledge hammers aren't an
option!!! Have thought of using a farady cage but am not sure if
that's going to be sufficient.)
