Nokia N78 Cell Phone User Manual


 
Potentially explosive
environments
Switch off your device when in any area with a potentially
explosive atmosphere, and obey all signs and
instructions. Potentially explosive atmospheres include
areas where you would normally be advised to turn off
your vehicle engine. Sparks in such areas could cause an
explosion or fire resulting in bodily injury or even death.
Switch off the device at refuelling points such as near gas
pumps at service stations. Observe restrictions on the use
of radio equipment in fuel depots, 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 and areas where the air
contains chemicals or particles such as grain, dust, or
metal powders. You should check with the manufacturers
of vehicles using liquefied petroleum gas (such as
propane or butane) to determine if this device can be
safely used in their vicinity.
Emergency calls
Important: Wireless phones, including this device,
operate using radio signals, wireless networks, landline
networks, and user-programmed functions. Because of
this, connections in all conditions cannot be guaranteed.
You should never rely solely on any wireless device for
essential communications like medical emergencies.
To make an emergency call:
1. If the device is not on, switch it on. Check for adequate
signal strength.
Some networks may require that a valid SIM card is
properly inserted in the device.
2. Press the end key as many times as needed to clear the
display and ready the device for calls.
3. Enter the official emergency number for your present
location. Emergency numbers vary by location.
4. Press the call key.
If certain features are in use, you may first need to turn
those features off before you can make an emergency call.
If the device is in the offline or flight profile mode, you
may need to change the profile to activate the phone
function before you can make an emergency call. Consult
this guide or your service provider for more information.
