■ 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 refueling 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 devices, 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 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.

Some networks may require that a valid SIM card is properly inserted in the device.

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.

4. Press the call key.
