Reference information
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.
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, vehicles using liquefied petroleum gas (such as propane or butane), and 
areas where the air contains chemicals or particles such as grain, dust or metal 
powders.
FCC regulations prohibit using your wireless device while in the air. The use of 
wireless telephones in an aircraft may be dangerous to the operation of the 
aircraft, disrupt the wireless telephone network, and may be illegal.
Failure to observe these instructions may lead to suspension or denial of telephone 
services to the offender, legal action, or both.
• EMERGENCY CALLS
Warning: Wireless phones, including this phone, 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 phone for 
essential communications like medical emergencies.
To make an emergency call:
1
If the phone 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 phone.
2
Press End key as many times as needed to clear the display and ready the 
phone for calls. 
3
Enter the official emergency number for your present location. Emergency 
numbers vary by location.
