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

168 Section 4A. Important Safety Information

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 C63.19 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
