My Uniden DECT phone has rechargeable batteries in the handset and the base station has a transformer power supply. The battery may be shot or the transformer may have failed?

Unplug the base station / charger for 10 minutes and then plug back in. It may reset. Also, check if the battery in the phone is fully charged. I had a power surge last year and unfortunately, it blew my base station and I had to get a new phone.

If you have no dial tone the problem is most likely the base station has failed, nothing you can do will kill the dial tone (no button you pushed etc.) except a failed base station.

go back to that base station and ensure that it recognizes the bedroom phone
follow the user manual to install other phones
the bedroom phone has to be the same exactly and not earlier versions or different makes

That indicates that the phone is not synced with the base station. Try putting it next to the base station and resetting. Here are some links that may help:

Maybe trying to pair the handset with the base station will solve your problem. Look in the manual how the pairing procedure is done for your phone.

If the pairing procedure is done, and the handset finds the base station and there's stil no dial tone, check if the cable from the telephone line is plugged in the base station of the phone and check if the other side of the cable is plugged in the wall phone outlet.

I hope this will solve your problem.

I gather you have the setting for tone and pulse set to tone? Also are you aware the ringing tone is generated by the phone company? When you dial a number and it connects, the phone provider sends the ring signal to the dial phone and the ringing signal to the dialing phone. Do you get a dial tone before dialing?

Resetting the voice message waiting indicator
When you receive a new voice mail message, the new message LED on the top of the handset flashes. In the event your message waiting light gets out of sync with your phone company's
voice messaging system, you can manually reset it back to the "No messages waiting" state.
1. Press and hold FiND on the base for five seconds.
Note: The handsets connected to the base will start to beep, however, keep pressing for five seconds.
2. A beep sounds and the message alert tone is reset.
Changing the dial mode
Your phone can communicate with the telephone network in two different ways: tone dialing or pulse dialing. These days, most base networks use a method called tone dialing, so your phone comes programmed for tone dialing. If your phone company uses pulse dialing, you will need to change your phone's dial mode. If you don't get a dial tone or can't connect to the telephone network, please follow the steps below to modify your phone's settings:
1. Press MENU/SELECT.
2. Select the Global Setup menu, and then the Dial Mode submenu.
3. Scroll to highlight Pulse.
4. Press MENU/SELECT. You will hear a confirmation tone.
If you ever need to change the dial mode back to tone dialing, follow the same procedure, but select Tone in step 3.

Finally for future ease of use, here is a link to the user manual were I copied the above information from:

I had the same problem and my hubby managed to reset the phone by simply unplugging it from the electical network. Just wait for few minutes (the date goes back to 1 Jan 2005), then plug it again and try to dial a number. It should work.
