Nokia 232N - Manual (Page 39)

Once locked, you can unlock the phone by repeating
the procedure described on the previous page.
If you make a mistake when locking or unlocking the
phone, the message
CODE ERROR will be displayed.
In this instance, start again from the beginning.
On entering the correct lock code:
– When locking the phone, the message
LOCKED will
be displayed, and will remain to remind you that the
phone is locked.
– When unlocking the phone, the message
UNLOCKED will appear briefly.
For other options, which provide more-selective
restrictions, you may use the Call restrict function
(Menu 14), page 43, or the Memory lock function
(Menu 15), page 44.
System Select (Menu 1)
Each cellular service area can have two cellular
service suppliers, called carriers. One carrier operates
the ‘A’ system, and the other carrier operates the ‘B’
system (these systems are generally known as
‘non-wireline’ and ‘wireline’, respectively). Your phone
is designed to work with both carriers.
This menu function allows you to program your phone
for optimum operation when in your home service
area or when away from your home area (this is called
roaming). You may select any of the following roaming
modes:
System A NAM System B NAM
