Expanding your phone
Your base supports a total of 12 cordless handsets: the one that came with the base and up to 11 DCX310, DRX312, or DWX317 accessory handsets.
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 the base, see page 37, or consult the accessory handset manual.
Any accessory handsets that came packaged with the base are already registered 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 37 or the manual for the accessory handset).
Conference calling
When an outside call comes in on the land line, two handsets can join in a conference call with that outside caller.
To join an ongoing call, press Talk/flash or Speaker.
To leave the conference call, hang up normally; the other handset remains connected to the call.
Privacy mode
You can prevent other handsets from joining a land line call. Start your call as usual, then press Menu/select: the display shows Call Privacy.
Press Menu/select again to turn privacy mode on (you’ll see 
in the display). When you hang up, privacy mode turns off automatically.
As long you have privacy mode on, no other handsets can interrupt your
call. To allow another handset to join the call, press Menu/select twice to turn privacy mode off.
