Some digital wireless phones may interfere with hearing aids. In the event
of such interference, consult your wireless provider.

determine if it is adequately shielded from external RF energy, or if you
have any questions.

Switch your phone off in any facility where posted notices so require.

regarding the use of radio equipment in fuel depots (fuel storage and
distribution areas), chemical plants, or where blasting operations are in
progress.
