Fcc Hearing Aid Compatibility (Hac) Regulations For Wireless Devices - Samsung Rugby Smart SGH-I847 User Manual

regulations posted in these areas instruct you to do so.
Hospitals or health care facilities may be using equipment
that could be sensitive to external RF energy.
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
190
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.
FCC Hearing Aid Compatibility (HAC)
Regulations for Wireless Devices
On July 10, 2003, the U.S. Federal Communications
Commission (FCC) Report and Order in WT Docket 01-309
modified the exception of wireless mobile devices under the
Hearing Aid Compatibility Act of 1988 (HAC Act) to require
digital wireless mobile devices be compatible with hearing
aids.
The intent of the HAC Act is to ensure reasonable access to
telecommunications services for persons with hearing
disabilities. While some wireless mobile devices are used
near some hearing devices (hearing aids and cochlear
implants), users 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.
