It turns off the phone transmitter.

There seems to be total paranoia that cell phones cause problems with

Extrapolating from this, as a physical therapist (as you guys over there

I have never heard of a radio ham running high power, with a pacemaker, who
has had an issue!
In discussion with a friend in the U.S. who is a radio ham, nor has he!
