Nokia 5800 - Manual (Page 19)

Downloading software updates may involve the transmission of large amounts of data
through your service provider's network. Contact your service provider for information
about data transmission charges.
Make sure that the device battery has enough power, or connect the charger before
starting the update.
Tip: To check the software version in your device, select Menu > Settings and
Phone > Phone mgmt. > Device updates.
Settings
Your device normally has MMS, GPRS, streaming, and mobile internet settings
automatically configured in the device, based on your network service provider
information. You may have settings from your service providers already installed in your
device, or you may receive or request the settings from the network service providers
as a special message.
Access codes
If you forget any of the access codes, contact your service provider.
● Personal identification number (PIN) code — This code protects your SIM card against
unauthorized use. The PIN code (4 to 8 digits) is usually supplied with the SIM card.
After three consecutive incorrect PIN code entries, the code is blocked, and you need
the PUK code to unblock it.
● UPIN code — This code may be supplied with the USIM card. The USIM card is an
enhanced version of the SIM card and is supported by UMTS mobile phones.
● PIN2 code — This code (4 to 8 digits) is supplied with some SIM cards, and is required
to access some functions in your device.
● Lock code (also known as security code) — The lock code (5 digits) helps you to
protect your device against unauthorized use. The preset code is 12345. You can
create and change the code, and set the device to request the code. Keep the new
code secret and in a safe place separate from your device. If you forget the code and
your device is locked, your device will require service and additional charges may
apply. For more information, contact a Nokia Care point or your device dealer.
● Personal Unblocking Key (PUK) code and PUK2 code — These codes (8 digits) are
required to change a blocked PIN code or PIN2 code, respectively. If the codes are
not supplied with the SIM card, contact the operator whose SIM card is in your device.
● UPUK code — This code (8 digits) is required to change a blocked UPIN code. If the
code is not supplied with the USIM card, contact the operator whose USIM card is in
your device.
Prolong battery life
Many features in your device increase the demand on battery power and reduce the
battery lifetime. To save battery power, note the following:
● Features that use Bluetooth technology, or allowing such features to run in the
background while using other features, increase the demand on battery power. Turn
Bluetooth technology off when you do not need it.
