Chapter 7 – Safety Information

Handling Precautions

To avoid damage due to the accumulation of static charge, use proper precautions when handling any cellular
device. Although input protection circuitry has been incorporated into the devices to minimize the effect of static
build-up, use proper precautions to avoid exposure to electronic discharge during handling and mounting the
device.

RF exposure: Separation between Antenna and User

Regarding RF Exposure, there is a minimum distance of 20 cm between the devices radiating structures (the
antenna) and the body of users.

Wireless devices could generate radiation. Other nearby electronic devices, like microwave ovens, may also
generate additional radiation to the user causing a higher level of RF exposure.

Radio Frequency (RF) Safety

Due to the possibility of radio frequency (RF) interference, it is important that you follow any special regulations
regarding the use of radio equipment. Follow the safety advice given below.

Operating your device close to other electronic equipment may cause interference if the equipment is
inadequately protected. Observe any warning signs and manufacturers’ recommendations.

Different industries and businesses restrict the use of cellular devices. Respect restrictions on the use of
radio equipment in fuel depots, chemical plants, or where blasting operations are in process. Follow
restrictions for any environment where you operate the device.

Do not place the antenna outdoors.

Switch OFF your wireless device when in an aircraft. Using portable electronic devices in an aircraft may
endanger aircraft operation, disrupt the cellular network, and is illegal. Failing to observe this restriction
may lead to suspension or denial of cellular services to the offender, legal action, or both.

Switch OFF your wireless device when around gasoline or diesel-fuel pumps and before filling your vehicle
with fuel.

Switch OFF your wireless device in hospitals and any other place where medical equipment may be in use.

Interference with Pacemakers and Other Medical Devices

Potential interference

Radio frequency energy (RF) from cellular devices can interact with some electronic devices. This is
electromagnetic interference (EMI). The FDA helped develop a detailed test method to measure EMI of implanted
cardiac pacemakers and defibrillators from cellular devices. This test method is part of the Association for the
Advancement of Medical Instrumentation (AAMI) standard. This standard allows manufacturers to ensure that
cardiac pacemakers and defibrillators are safe from cellular device EMI.

The FDA continues to monitor cellular devices for interactions with other medical devices. If harmful interference
occurs, the FDA will assess the interference and work to resolve the problem.
