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 Wireless Providers.
To make an emergency call:
1. If the phone is not on, switch it on.
