Question about Uniden TRU9480 Cordless Telephone

Open Question

Phone rings. No one there. No dial tone!

So the phone rings and I answer it. Can't hear anything. When I hang up, there's no dial tone. It comes back on by itself OR I once unplugged the power and replugged it back in and the dial tone came back on. This doesn't happen all the time. Just occasionally, randomly.

The base is plugged into the same outlet as the fridge--could this be related?

It's definitely at the base as I plugged in a corded phone with a dial tone at the same time the uniden cordless was unable to get a dial tone. It wasn't until I unplugged the power that I got the dial tone.

    Same issue reported by "ajroszak". The phone rings and when I answer the call the phone dies...nothing....kaput. I have to disconnect/reconnect to the AC power then it goes back to normal It happens to me fequently, several times during the month....very annoying.
    I have corded phone that worked fine while I had the issue with the Uniden, so can not blame my phone carrier.

    I have the same problem exactly, and would like to know the solution. I believe this is a crappy product, since this fault is obviously common. I have used this phone only maybe 50 times in total since new. My previous cordless, a Panasonic, lasted many years without defect.

SOURCE: Uniden TCX805 Cordless "loses" dial tone

Sounds like the switching mechanism that creates the link is stuck. When you answer your phone, you allow the voltage to complete it's path and you either answer the phone or you hear dial tone. If that switch is stuck closed, even though you hung up the phone, the connection is still alive. When you try to pick the phone back up later, the connection is still closed, but your phone has already passed it's "if you would like to make a call" message and you hear no dial tone. Unplugging the power to the phone resets this switch and all is good again.....that is until it gets stuck again. I have seen this problem with phones after a near lightening strike at the house. Sounds like you need to get a new phone as I don't think this is repairable.

SOURCE: Uniden cordless phone. No dial tone.

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.

I had the same problem as long as they are plugged in correctly and you put the #2 handset into the #1 cradle to register it to your base then try hanging the phone up several times. These are expandable phones so that I believe you can keep adding other handsets. So sometimes they think you have a few more handsets than you really have so when you hang up it may not know what handset you are hanging up #1 #2 or #3 #4 etc. So I had to keep hanging them up until it finally hung up. Then I had to re install them so it knew I only had 2 hand sets. So then you start from the beginning, like when you took it from the packaging. I hate these phones. I ended up replacing them with different ones. Plus I always keep a rotery phone laying around put away because during a power outage you still can plug in an old dial phone and it will work! Nothing like old technology.

Make sure the phone and the phone base is turned on. Check the phone cables at the back of the phone base where you charge your cordless phone. It should be properly connected to the phone jack on the wall and at the back of the phone base. Try unplugging and replugging it back in. If that fails, try changing the phone cable. If still there's nothing, try to connect another phone on the phone line. If you get a dial tone, it means you have a problem with the wireless phone set, if not, contact your phone company.

Why can't I rec or make calls?


What is happening when a call comes in are they getting a busy signal? If so your line is shorted out.. unplug all phones and see if caller hears a ring.. Then 1 at a time plug phones in. Check for a dial tone and press a digit, hang up and check and see if dial tone returns, repeat this on all phones, until you get to the phone that does not give you dial tone back after dialing a digit. That will be your bad phone... If the line was ring busy after all phones unplugged, call repair service..

How can I get more than 3 rings? I am in my 70s and disabled. I can not get to my phone to answer in 3 rings. I miss calls due to this.


  1. Pick up the home phone receiver, wait for dial tone, and dial *94. You'll hear 3 beeps followed by dial tone.
  2. Enter the number of rings you want (between 2 and 9).
  3. Listen for 2 confirmation beeps and hang up.

How does one forward incomming calls on a uniden 2.4ghz cordless phone?


Cordless phones can not 'forward' a call to an outside line.
Forwarding must be controlled by the ATT, Verizon, or landline provider.
Please contact your provider to determine if you have call forwarding feature built into your service package.

Then, follow the instructions of your landline phone provider.
Here is the instructions for Verizon:


Activating Call Forwarding
You can activate Call Forwarding whenever you want your calls to be sent to another phone, including a mobile phone. Once activated, all your calls will be sent to the forwarding number you request. Each time a call is forwarded, you will hear one short reminder tone on your home phone, but you will not be able to answer the call from your home number.

  1. Lift your telephone's receiver and listen for a dial tone.

  2. Press star.gif7.gif2.gif.
    In some areas you must use 7.gif2.gifpound.gif
    Dial 1172 on rotary or pulse-dialing phones.

  3. When you hear the tone, set or change the Call Forwarding number by dialing the telephone number where you want your calls transferred.
    You will hear the number you entered ring. When the number is answered, Call Forwarding is activated.

  4. If the call is not answered or the line is busy, hang up and call the number again within two minutes.
    You will hear two short tones telling you that Call Forwarding is activated.

  5. Hang up the receiver.

When dialing with my logitech skype phone I can't hear any sound until the other person answers the phone. It only happens with skype to skype calls. It works perfectly calling regular phones.


This is probably because dial tones and ringing tones are part of an archaic system. Your cell phone still makes these noises as a courtesy, and you hear the dial tones/ringing tones when you make regular calls because your phone is communicating with the standard phone system.

2. Press * 73.
In some areas you must use 73#
Dial 1173 on rotary or pulse-dialing phones.
