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. Do not store or carry flammable liquids, gases, or
explosive materials in the same compartment as the device, its
parts, or enhancements.
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: This device operates using radio
signals, wireless networks, landline networks, and
user-programmed functions. If your device
supports voice calls over the internet (internet
calls), activate both the internet calls and the
cellular phone. The device will attempt to make
emergency calls over both the cellular networks
and through your internet call provider if both are
activated. Connections in all conditions cannot be
guaranteed. You should never rely solely on any
wireless device for essential communications like
medical emergencies.
