We have a Uniden 6.0 digital ansering system with 2 cordless handsets. There is no dial tone to the handsets. We have changed the battery but still no dial tone. However, when an incoming call comes in the phone will ring but there is no way to answer as there is no dial tone available. What can we do next?

Registering Handsets to the Base
Whichever handset you choose to charge in the base is automatically
registered to the base. Any additional handsets must also be registered to
the base before you can use them.
Be sure both handsets are fully charged.
One at a time, place each handset in the base. The charge/in use LED on
the base begins to flash, indicating the base is registering the handset.
Wait for at least five seconds, then pick up the handset and press
[talk/flash]. If the display shows TALK, the handset is registered. If not,
place the handset in the base to try again.
Press [end] and continue with the next handset.
Note:
Once both handsets are registered, it doesn’t matter which
handset is placed in the base or the charger.
When you charge the handsets, Caller
ID summary screen and the name of
the handset appears.

Hi peddler65, did you plug your phone into another area to see if there is a dial tone. Then if not call the phone company or find the D-mark (where your dial tone ) comes into your home and put a jack on that and plug a phone in with all phones in the house unplugged.

Thanks.

It may not be registed with the main unit. You may need to register the handset. With my uniden all i have to do is put it in the main base until it says what handset it is (it should be a number).

If you have any questions please dont hesitate to ask

You need to reset the main base unit. Unplug the power from the back of the base. While the power is disconnected, press and hold the delete key while reconnecting the power. Wait for a long beep tone. When the display shows 88 or P, press play button one time. If you have a phone without an answering machine, disconnect the power from the back of the base, press and hold find hs button while reconnecting power.

Unplug the power supply to the base of the main handset, wait 10 seconds and plug back in.
