Nokia 5233 Cell Phone User Manual


 
Switch off your device before boarding an aircraft. The use of wireless teledevices
in an aircraft may be dangerous to the operation of the aircraft and may be illegal.
Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere. Obey
all posted instructions. Sparks in such areas could cause an explosion or fire
resulting in bodily injury or death. Switch off the device at refuelling points such as
near gas pumps at service stations. Observe restrictions 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 areas where you would be advised to turn off your vehicle
engine, below deck on boats, chemical transfer or storage facilities and 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: This device operates using radio signals, wireless networks,
landline networks, and user-programmed functions. If your device supports voice
calls over the internet (internet calls), activate both the internet calls and the cellular
phone. The device will attempt to make emergency calls over both the cellular
networks and through your internet call provider if both are activated. 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.
Depending on your device, you may also need to complete the following:
Insert a SIM card if your device uses one.
Remove certain call restrictions you have activated in your device.
Change your profile from offline profile mode to an active profile.
