Turning Off Your Phone in Dangerous Areas
To avoid interfering with blasting operations, turn your phone
off when in a blasting area or in other areas with signs
indicating two-way radios should be turned off. Construction
crews often use remote-control RF devices to set off explosives.
Turn your phone off when you're in any area that has a
potentially explosive atmosphere. Although it's rare, your phone
and accessories could generate sparks. Sparks can cause an
explosion or fire, resulting in bodily injury or even death. These
areas are often, but not always, clearly marked. They include:
Fueling areas such as gas stations.
Below deck on boats.
Fuel or chemical transfer or storage facilities.
Areas where the air contains chemicals or particles such
as grain, dust, or metal powders.
Any other area where you would normally be advised to
turn off your vehicle's engine.
Note Never transport or store flammable gas, flammable liquids,
or explosives in the compartment of your vehicle that
contains your phone or accessories.
Restricting Children's Access to Your Phone
Your phone is not a toy. Do not allow children to play with it as
they could hurt themselves and others, damage the phone or
make calls that increase your Sprint invoice.

Using Your Phone With a Hearing

Aid Device

Your phone has been tested for hearing aid device
compatibility. When some wireless phones are used with
certain hearing devices (including hearing aids and cochlear
implants), users may detect a noise which can interfere with the
effectiveness of the hearing device.
Some hearing devices are more immune than others to this
interference noise, and phones also vary in the amount of
interference noise they may generate. ANSI standard C63. 1 9
was developed to provide a standardized means of measuring
both wireless phone and hearing devices to determine usability
rating categories for both.
Ratings have been developed for mobile phones to assist
hearing device users find phones that may be compatible with
their hearing device. Not all phones have been rated for
compatibility with hearing devices. Phones that have been
rated have a label located on the box. Your M520 phone by
Samsung has an M4 rating .
These ratings are not guarantees. Results will vary depending
on the user's hearing device and individual type and degree of
hearing loss. If a hearing device is particularly vulnerable to
interference noise; even a phone with a higher rating may still
cause unacceptable noise levels in the hearing device. Trying
