Dialling pause
When using private branch exchanges, it is necessary to dial an access code to obtain the
dialling tone for an outside line. When using some older private branch exchanges, it takes
a little time before the dialling tone becomes audible. In the case of such private branch ex-
changes, a dialling pause can be inserted after the number for an outside line in order to
continue dialling directly without having to wait for the dialling tone.
3 sec. Insert a dialling pause
The actual phone number is dialled a certain time after the number for an outside line.
The dialling pause can also be entered with the phone numbers in the phone
book.
Caller number display (CLIP
1
)
The caller number display (CLIP) is a supplementary service offered by your
telephone network provider. Contact your network provider for further informa-
tion.
If this function is available with your telephone line, the number of the caller appears in the
display when the phone rings. If the caller has suppressed transmission of his phone
number, the corresponding message appears in the display. The phone number is not dis-
played and, as a result, is not stored in the call list.
Answering machine in the telephone network
An answering machine in the telephone network is a supplementary service offered by
many telephone network providers. If your telephone network provider offers an answering
machine in the telephone network for you, an icon on the display informs you of new mess-
ages received (VMWI
2
). This function can only be used when your telephone network pro-
vider actually offers the service. Contact your network provider for further information.

The international GAP

standard regulates the compatibility of handsets and base stations
from different manufacturers. As a result, it is possible to integrate SWITEL devices and de-
vices from other manufacturers together in one telephone system. It is possible, however,
that some functions are not available.
Multiple handsets
Up to 5 handsets can be registered on the base station.
Registering handsets
Before starting to register a handset, switch the base station to Registration mode.
3 sec. Enable Registration mode
Now register the handset, Page 15. The currently valid PIN code is used for registration
purposes; Page 15.
The handset is automatically assigned an internal call number following registration. The in-
ternal call number appears in the display.
