Potentially Explosive Environments 
Switch your phone off when in any area with a potentially explosive 
atmosphere and obey all signs and instructions. Sparks in such areas 

could cause an explosion or fire resulting in bodily injury or even death. 
Users are advised to switch the phone off while at a refueling point 
(service station). Users are reminded of the need to observe restrictions 
on the use of radio equipment in fuel depots (fuel 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), areas where the air contains chemicals or particles, such as 
grain, dust or metal powders, and any other area where you would 

normally be advised to turn off your vehicle engine. 
Emergency Calls 
This phone, like any wireless phone, operates using radio signals, wireless 
and landline networks as well as user programmed functions, which 
cannot guarantee connection in all conditions. Therefore, you should 
never rely solely on any wireless phone for essential communications 

(medical emergencies, for example). 
Remember, to make or receive any calls the phone must be switched on 
and in a service area with adequate signal strength. Emergency calls may 
not be possible on all wireless phone networks or when certain network 
services and/ or phone features are in use. Check with local service 

providers. 
To make an emergency call: 

1.

If the phone is not on, switch it on. 

2.

Key in the emergency number for your present location (for 
example, 911 or other official emergency number). Emergency 
numbers vary by location. 

3.

Press 

. 

If certain features are in use (call barring, for example), you may first 
need to deactivate those features before you can make an emergency call. 
Consult this document and your local cellular service provider. 
When making an emergency call, remember to give all the necessary 
information as accurately as possible. Remember that your phone may be 
the only means of communication at the scene of an accident; do not cut 

off the call until given permission to do so. 
Restricting Children's access to your Phone 
Your phone is not a toy. Children should not be allowed to play with it 
because they could hurt themselves and others, damage the phone or 

make calls that increase your phone bill.
