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
devices. Not all mobile devices have been rated. Mobile devices
that are rated have the rating on their box or a label located on
the box.
The ratings are not guarantees. Results will vary depending on
the user's hearing device and hearing loss. If your hearing device
happens to be vulnerable to interference, you may not be able to
use a rated mobile device successfully. Trying out the mobile
