Notes on using the handset(s) at more than one base unit
The base unit number which the handset is currently in contact with can be
displayed in the stand-by mode (p. 52).
Calls (both incoming and outgoing) can be conducted only via the displayed
base unit (even if the radio areas overlap with neighbouring base units).
Intercom calls can be conducted within the radio area of the current base unit,
but not with units in neighbouring radio areas.
If the handset moves to another radio area, it loses contact with the previous
base unit and a radio link with the new base unit is set up automatically.
("Automatic base unit access"–see p. 69).
Calls in progress are cancelled when the unit moves to another radio area.
You can deactivate "Automatic base unit access" at a base unit. By selecting
"Specified base unit access" (p. 69), you can choose the base unit where you
want the handset to operate. This is important in the overlap area between two
radio areas. Here you can choose the base unit/telephone line from which you
can make/receive outgoing calls.
