Emergency Calls
Section 13
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.
