That appears to be what Jim has, as well.  I.e., the manufacturer has decided
that there is some value to be able to disable the wireless access.  (or,
just figured it was an option/feature they could charge for!)

Ours doesn't -- just a hook for the "optical interrupter" (which aborts
a CLOSE operation in progress, among other things)

Our cordless phone doesn't have any mechanism to disable the "cordless" aspect
(utilizing just the "base station" capability).  Actually, that's true of ALL
the cordless phones we've had -- including the pricey "industrial" units!
[I literally unplug the base unit from the PSTN when I want to disable it]

I can only disable the wireless capability in my "routers" through the
web-based management console -- and, all are different.

We can disable the wireless entry feature on the car -- but only by
knowing how to access the "settings" and having some knowledge of the
terse, cryptic descriptions of each "setting".

Do RC planes/cars/boats have a switch that allows the radio control
to be disabled (or, do you just kill "power")?

Etc.

I.e., the wireless aspect of many devices seems to be considered so
fundamental that including a means of disabling it appears to be an
afterthought, in many cases!
