Uniden DECT4096 English Owners Manual - Page 31

Using Multi-station Features The expandable base works together with the accessory handsets to give you some useful multi-station features. (A station can be any cordless handset or the base.) You must have at least one accessory handset to use the features in this section. Expanding Your Phone  Your base supports a total of ten DCX400 accessory handsets, including any that were supplied with your phone.  Your base might be compatible with other Uniden accessory handsets: please visit our website for a list of compatible handsets.  Accessory handsets must be registered to the base before you can use them. Handsets that aren't registered display a Handset not registered message. For instructions on registering handsets to this base, see page 44 or refer to the manual that came with the accessory handset.  Any accessory handsets that came packaged with the base are already registered to that base for you.  If a handset was previously registered to a base, you have to reset it so you can register it to a new base (see page 44 for DCX400 handsets). Using Multi-Station Conference Calling  When an outside call comes in on either line, the base and four cordless handsets can join in a six-way conference call with the outside caller.  To join a call in progress, just connect to the active line (press Line1 or Line2). 29
