Health and Safety Information 143
Vehicles
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 also consult the manufacturer of any
equipment that has been added to your vehicle.
Posted Facilities
Switch your mobile device off in any facility
where posted notices require you to do so.
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. Areas with a potentially
explosive atmosphere are often, but not always,
clearly marked. They include below deck on
boats, chemical transfer or storage facilities,
vehicles using liquefied petroleum gas (such as
propane or butane), areas where the air contains
chemicals or particles, such as grain, dust, or
metal powders, and any other area where you
would normally be advised to turn off your
vehicle engine.
When your Device is Wet
Do not turn on your device if it is wet. If your
device is already on, turn it off and remove the
battery immediately (if the device will not turn off
or you cannot remove the battery, leave it as-is).
Then, dry the device with a towel and take it to a
service center.
FCC Hearing Aid Compatibility
(HAC) Regulations for Wireless
Devices
The U.S. Federal Communications Commission
(FCC) has established requirements for digital
wireless mobile devices to be compatible with
hearing aids and other assistive hearing devices.
When individuals employing some assistive
hearing devices (hearing aids and cochlear
implants) use wireless mobile devices, they may
detect a buzzing, humming, or whining noise.
Some hearing devices are more immune than
others to this interference noise, and mobile
devices also vary in the amount of interference
they generate.
The wireless telephone industry has developed a
rating system for wireless mobile devices to
assist hearing device users find mobile devices
that may be compatible with their hearing
