System Selection; Public System Selection - Nokia 5120 Owner's Manual

System selection

Your phone is capable of working in residential, private, and
public systems. You can choose how your phone selects a
network to use.
This feature is Menu 5 in your phone. The default is
Automatic, which means your phone automatically
searches for networks available to you and chooses the
appropriate one. Every time you switch on your phone,
Automatic is selected.
If you choose Manual, your phone displays a list of available
and unavailable networks. (You can't use unavailable
networks.) Scroll through the choices and press OK when
you reach the one you want.
If you choose New Search, your phone begins a new search
for new private and residential systems. When it finds the
best new system, it displays it. You can then select it or start
another search by pressing Next.
Note: The Manual and New search features can be used
only when your primary phone number (NAM1) is selected.
See page 32.
To switch from private to public
If you are in a private system and want access to a public
system, press and hold Menu when you are not in a call.
Your phone will display Search public systems? Press OK
and your phone will use the public system for the next
outgoing call. After the call it will revert to Automatic
system selection.

Public system selection

When your phone leaves its home system, it is roaming. Like
other public systems, your home system is either type A or B.
When your phone is roaming, it can search for home-type
systems (same type as your home system) or non-home-
type systems (opposite type as your home system).
