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 accessory handsets and 2 MULTIRANGETM chargers, including any that were supplied with your phone. It is compatible with both the DCX400 handset with charger and the DRX402 handset with MULTIRANGETM charger.  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 40 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 40 for DCX400 and DRX402 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 sixway conference call with the outside caller.  To join a call in progress, just connect to the active line (press LINE1 or LINE2).
