Access Codes
There are several access codes that are used by your
phone and its SIM card. These codes help you protect
the phone against unauthorised use.
The access codes (except for the PUK and PUK2
codes) can be changed using Security menu options.
See page 98 for further details.
Phone Password
The phone password can be set to avoid unauthorised
use of your phone. The password generally supplied
with the phone is 0000. You are recommended to
change it before you start using your phone. Keep the
new password secret and in a safe place, separate
from the phone.
PIN
The PIN (Personal Identification Number) protects
your SIM card against unauthorised use. The PIN is
usually supplied with the SIM card. When the PIN
Check feature is enabled (menu option 5-3-1), the PIN
is needed each time the phone is switched on.
If you key in an incorrect PIN three times in
succession, key in the PUK and press OK. Key in a
new PIN and press OK. Key in the new PIN again and
press OK.
The audio quality of the call is poor
• Check the signal strength indicator in the display
( ); the number of bars after it indicates the
signal strength from strong ( ) to weak ( ).
• Try moving the phone slightly or moving closer to
a window if you are in a building.
No number is dialled when you recall a
phonebook entry
• Check that the numbers have been stored
correctly, by using the Phonebook Search feature.
• Re-store them, if necessary.
If the above guidelines do not enable you to solve
the problem, take a note of:
• The model and serial numbers of your phone
• Your warranty details
• A clear description of the problem
Then contact your local dealer or SAMSUNG
after-sales service.
