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.

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.
