Hearing aids
Some digital wireless devices may interfere with some
hearing aids. If interference occurs, consult your
service provider.
Vehicles
RF signals may affect improperly installed or
inadequately shielded electronic systems in motor
vehicles such as electronic fuel injection systems,
electronic antiskid (antilock) braking systems,
electronic speed control systems, and air bag systems.
For more information, check with the manufacturer, or
its representative, of your vehicle or any equipment
that has been added.
Only qualified personnel should service the device or
install the device in a vehicle. Faulty installation or
service may be dangerous and may invalidate any
warranty that may apply to the device. Check regularly
that all wireless device equipment in your vehicle is
mounted and operating properly. Do not store or carry
flammable liquids, gases, or explosive materials in the
same compartment as the device, its parts, or
enhancements. For vehicles equipped with an air bag,
remember that air bags inflate with great force. Do not
place objects, including installed or portable wireless
equipment in the area over the air bag or in the air bag
deployment area. If in-vehicle wireless equipment is
improperly installed and the air bag inflates, serious
injury could result.
Using your device while flying in aircraft is prohibited.
Switch off your device before boarding an aircraft. The
use of wireless teledevices in an aircraft may be
dangerous to the operation of the aircraft, disrupt the
wireless telephone network, and may be illegal.
Potentially explosive
environments
Switch off your device when in any area with a
potentially explosive atmosphere, and obey all signs
and instructions. Potentially explosive atmospheres
include areas where you would normally be advised to
turn off your vehicle engine. Sparks in such areas could
cause an explosion or fire resulting in bodily injury or
even death. Switch off the device at refuelling points
such as near gas pumps at service stations. Observe
restrictions on the use of radio equipment in fuel
depots, storage, and distribution areas; chemical
plants; or where blasting operations are in progress.
Areas with a potentially explosive atmosphere are
often, but not always, clearly marked. They include
below deck on boats, chemical transfer or storage
facilities and areas where the air contains chemicals or
particles such as grain, dust, or metal powders. You
should check with the manufacturers of vehicles using
liquefied petroleum gas (such as propane or butane) to
determine if this device can be safely used in their
vicinity.
Emergency calls
Important: Wireless phones, including this
device, operate using radio signals, wireless networks,
landline networks, and user-programmed functions.
Because of this, connections in all conditions cannot be
guaranteed. You should never rely solely on any
