It is also possible to overwrite an existing registration by selecting that entry that should be overwritten instead
of selecting an “Empty” slot. This is displayed below.
NOTE: For the handset to function on different base systems, the handset must be completely out of range of
system 1 to connect to system 2.
6.4.2 Deregister
The handset can be deregistered from a registration. The user will in this case be prompted for a PIN code (base
deregistration PIN), the PIN code is default “0000” and cannot be changed via the handset. This is displayed
below.
When the registration that should be deregistered is selected, a warning message “Delete registration?” will be
displayed as seen above. The user then has to accept by pressing the left softkey “Yes”, or the right softkey “No”
to cancel the operation.
