RF signals may affect improperly installed or
inadequately shielded electronic systems in motor
vehicles. Check with the manufacturer or its
representative regarding your vehicle before using
your mobile device in a motor vehicle. You should

Potentially Explosive Environments

Switch your mobile device off when in any area with
a potentially explosive atmosphere and obey all signs
and instructions. Sparks in such areas could cause
an explosion or fire resulting in bodily injury or even
death.
Users are advised to switch the mobile device off
while at a refueling point (service station). Users are
reminded of the need to observe restrictions on the
use of radio equipment in fuel depots (fuel storage
and distribution areas), chemical plants, or where
blasting operations are in progress.
