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.

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.

There can be a lot of different things that could cause this. The first thing I would do is disconnect the telephone cord from the Uniden phon eand connect it to another telephone and see if you get a dial tone from it. If you do then we know that the telephon eline and the cord are OK so we go back to the Uniden telephone. Next, does the unit light up when you plug it in? are you sure that the telephone is getting AC Power? Are the displays on the handsets working? Does the handset display show "Handset XX" or does it show "Searching"? If it shows "Handset XX" then the base unit is getting power, if not the base unit may not be getting power.
If the base unit is getting power and the handsets are working and the power cord and jack were proven good by conecting another phone to them, then you would need to call uniden Customer Service for further trouble shooting or repair/replacement. the number is 1-800-297-1026
