4.5.2 Handset Replacement with Device Manager in DECT System
NOTE: The handset to be installed must not have any previous valid registrations. If it has a
valid registration, unsubscribe the handset.
1 Unsubscribe the old handset. If the unsubscribtion cannot be performed in the
handset, unsubscribe the handset via the DECT interface. Refer to the corresponding
IP-DECT documentation.
2 Subscribe the new handset with the same extension number as the old handset. The
subscription procedure is described in the Handset User Manual. During the
subscription procedure, the handset User ID is automatically set to be the same as
the extension number.
TIP: The User ID can be viewed in the handset by navigating to the menu:
Admin menu > Device info > User ID.
3 Insert the handset into a desktop charger or rack charger connected to Device
Manager or use an IP-DECT over-the-air connection. Navigate to the Numbers tab in
the Device Manager.
4 Navigate to the Numbers tab in the Device Manager.
The new handset now has the same User ID as the old handset. It is automatically
synchronized and data and parameter settings from the old handset are transferred
to the new handset.
The synchronization takes a while if the Contacts in the original handset contains a
large number of entries.
4.6 Handset Replacement with WinPDM
To see which data that is replaced during this process, see 4.5.1 Data Included in a
Replacement Transfer on page 11.
Both the old handset and the new handset must be of the same device type. The same
extension number is assigned to the new handset.
The new handset should not be subscribed to the PBX yet.
1 Perform a factory reset, see 4.3 Perform a Factory Reset on page 10, if the new
handset has been previously used.
2 Make sure that the handset is saved in the WinPDM. In the Numbers tab, a saved
handset has the symbol in the Saved column. If not, right-click the handset and
select “Save” to transfer the settings to the new handset later on.
NOTE: If the old handset settings cannot be saved, stop the replacement procedure. Instead
register the new handset and follow the instructions for installing a handset, see 3.2
Installing a New Handset on page 7.
