Setup
User group
§Menu§ Setup User group
select a function:
If offered by the service provider,
this service enables groups to be
formed. These have access, for
example, to internal (company)
information or special tariffs which
apply to them. Check with your
service provider for details.
User group
Activate or deactivate the function.
“User group” must be deactivated
for normal phone use.
Select group
You may select or add groups other
than the preferred groups (see
below). The service provider
supplies you with code numbers for
the groups.
Outgoing access
In addition to network control for a
user group, it is possible to choose
whether outgoing calls outside the
group are permitted. If the function
is deactivated, only calls within the
group are permitted.
Preferred group
If activated, only calls within this
standard user group can be made
(depending on the network
configuration).
© Z During a Call
§Menu§ Setup During a call
select a function:
Call waiting
If you are registered for call waiting,
you can confirm whether it is set.
You can also activate or deactivate
the function (p. 20).
Hide ID
When you make a call, your
number may be displayed on the
recipient's phone (depending on the
service provider).
To suppress this display, you may
activate the “Hide ID” mode for the
next call or for all subsequent calls.
(You may need to register with your
service provider for this function.)
Prefix code
Prefix codes are needed when
dialing international numbers. For
example all international calls placed
from the US require the international
access prefix "011". To place an
international call in TDMA mode,
you may still access the international
dialing codes through
+List , but you
will be prompted to enter the
international access prefix. These
prefix codes must be preset (see
p. 23 Placing International Calls).
