Additional information
If you are outside your home network, your
phone automatically dials another GSM
network.
If the signal strength of the preferred net-
work is inadequate when you switch on the
phone, the phone may register in a different
network. This can change when the tele-
phone is next switched on or if another net-
work is selected manually.
Band selection
Select either GSM 900, GSM 1800,
or GSM 1900. Make sure that your
service provider also supports the
selected band.
Fast search
When this function is active, net-
work reconnection is speeded up
(standby time is reduced).
User group
Depending on your service provider,
you can create groups with this serv-
ice. These have access, for example,
to internal (company) information,
or special tariffs apply to them. The
details can be clarified with your
service provider.
Active
Activate/deactivate function. "User
b
group" must be deactivated for nor-
mal phone use.
Select group
You can select or add groups other
than preferred groups (see below).
Code numbers for the groups are ob-
tained from your service provider.
All outgoing
In addition to network control for a
user group, it is possible to set
whether outgoing calls outside the
group are permitted. If the function
is deactivated, only calls within the
group are permitted.

If activated, calls may only be made
within this standard user group (de-
pending on the network
