Posted Facilities
Switch your phone off in any facility where posted
notices require you to do so.
Potentially Explosive Atmospheres
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
refuelling 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).
