Hearing aids
Some digital wireless devices may interfere with some hearing aids.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic systems in motor vehicles such as electronic fuel
injection, electronic antilock braking, electronic speed control, and air bag systems. For more information, check with the
manufacturer of your vehicle or its equipment.
Only qualified personnel should service the device or install the device in a vehicle. Faulty installation or service may be
dangerous and may invalidate your warranty. 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 accessories. Remember that air bags inflate with great force. Do not place your device or accessories in the
air bag deployment area.
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 and may be illegal.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere. Obey all posted instructions. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or death. Switch off the device at refuelling points such as near gas
pumps at service stations. Observe restrictions 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
areas where you would be advised to turn off your vehicle engine, below deck on boats, chemical transfer or storage facilities
and 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 may 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.
To make an emergency call:
1 If the device is not on, switch it on. Check for adequate signal strength. Depending on your device, you may also need to
complete the following:
• Insert a SIM card if your device uses one.
• Remove certain call restrictions you have activated in your device.
• Change your profile from Offline or Flight profile to an active profile.
2 Press the end key as many times as needed to clear the display and ready the device for calls.
3 Enter the official emergency number for your present location. Emergency numbers vary by location.
4Press the call key.
When making an emergency call, give all the necessary information as accurately as possible. Your wireless device may be the
only means of communication at the scene of an accident. Do not end the call until given permission to do so.
