Additional safety information
■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: 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.
4. Press 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.
■Hearing aids
Some digital wireless devices may interfere with some hearing aids. If interference occurs,
consult AT&T.
