Vehicles
Radio signals may affect improperly installed or inadequately shielded electronic systems in vehicles. For more
information, check with the manufacturer of your vehicle or its equipment.
Only qualified personnel should install the device in a vehicle. Faulty installation may be dangerous and invalidate your
warranty. Check regularly that all wireless device equipment in your vehicle is mounted and operating properly. Do not
store or carry flammable or explosive materials in the same compartment as the device, its parts, or accessories. Do not
place your device or accessories in the air bag deployment area.
Safety and texting while driving
Safety should be every driver's first priority. Drivers must obey all local laws that may include restrictions on the use of
mobile telephones or accessories while driving. If use is legal, always keep your hands free to operate the vehicle while
driving and use a handsfree device whenever possible. Suspend calls in heavy traffic or hazardous weather. Get to know
your mobile phone and its features and make any necessary information inputs prior to driving. Do not input data or
engage in text messaging while driving. Mobile telephones should not be used when use may be a distraction to the
driver.
The Cellular Telecommunications & Internet Association (CTIA) has published further info and tips on safe use of cellular
telephones at www.ctia.org/consumer_info/safety, which we encourage you to review.

Potentially explosive environments

Turn your device off in potentially explosive environments, such as near gas station pumps. Sparks may cause an
explosion or fire resulting in injury or death. Note restrictions in areas with fuel; chemical plants; or where blasting
operations are in progress. Areas with a potentially explosive environment may not be clearly marked. These usually
are areas where you are advised to turn your engine off, below deck on boats, chemical transfer or storage facilities,
and where the air contains chemicals or particles. Check with the manufacturers of vehicles using liquefied petroleum
gas (such as propane or butane) if this device can be safely used in their vicinity.
