Question about Uniden TRU9485 Cordless Phone

1 Answer

Tru 9485 The "Call Waiting ID" does not work. Trouble with the phone company, phone line, phone jack and power supply have been ruled out. A basic system reset was tried and CIDCW worked one time and then quit. "Caller ID" function does work. Uniden web site troubleshooting techniques tried. The only part of the CIDCW that does work is the tone received and the "incoming line" notice on the LCD. All other phone jacks were cleared but this did not help.

The information on handset says 'the line is busy' unable to make or receive calls , when i call the phone it just gives ringing tone

The fact that it just rings when you call it indicates your line is open, which could be a wiring issue at a modular jack, or the modular cord between the jack and the phone, if it isn't just that it came unplugged.

I keep an old touch tone phone handy to act as a test phone to rule out a failed phone. With today's network terminations a customer can access a test jack outside your home/premise to test the line provided by the phone company before it heads inside to your phone wiring. If the phone works there at that modular jack, the issue is inside, if it doesn't, the issue is with the line to the phone company.

Once you narrow it down to inside wiring you can inspect any or all modular jacks to make sure the red & green wires are not broken at the screw terminals and that the modular jack wires are indeed firmly tightened to the same color wire terminal screw.

And last, another phone on the same line that is off-line or not hung up could cause the phone company equipment to isolate your line until the phones are hung up for a period of time to restore the line. So check that all phones are hung up, even cordless ones associated with the base on that particular line.

I have a panasonic phone set tg1103. I used it in a previous house and now cannot get it to work in my new home. How do i reset it to find my phone line. Do i need to set it to factory settings and if...

You should not have to do anything to make the base find the phone line as long as it's plugged into a working phone jack and the AC power is on.

Have you tested the phone jack where you are connecting the base to be sure it's working? You can check with a simple, basic corded type phone. (You should have one of these on hand anyway, in case your power goes out. Without AC power, cordless phones won't work since their base unit would be off. The basic corded phone gets its power from the phone line so it will keep going. It's a good thing to have.) Plug the phone in and see if you have dialtone at the jack. You don't know what kind of phones the former residents had and how their jacks were wired. The one you're using may have been set up on a second line, for example.

If you don't find dialtone at the jack, you can try others and move the base unit as necessary, or see about having the wiring corrected. The model number of your phone is a UK version, and I don't know the rules regarding who can do telephone wiring there. Here in the US you can do the work yourself, hire a contractor, or contact the telephone service provider.

If you find the jack is working, something may have happened to the cordless base unit during the move. Try another cord; maybe the one you're using was damaged. Then your remaining option is to see about servicing or replacing the phone if it's still not working.

My phone seems dead although the computer connection and the fax are working. Help!

First try a new phone cord and a different phone. Are all items attached to one jack with one phone number? If you have multiple jacks, check if the phone works on another jack. If you have separate phone lines, check if the phone works on the computer/fax line. Check if the phone works without the other devices (particularly if daisy chained). Swap out all of the cables in the chain if it works directly.

In the multiple line case, if your phone works on one line and not the other, check if a phone works on that line at the incoming service. (If you are lucky, the incoming service has RJ-11 connections and you can test this yourself. Otherwise, you'll need a service person.) I've had several cases where mice or something broke one of two incoming phone lines outside so I just lost that one phone number. If the outside service doesn't work, call your phone company. They will fix it for free. If the outside service works, check your jack for loose wires. Check any exposed wiring in the house for damage. If the wiring isn't damaged in the exposed areas or at the jack, you'll probably need a service call (for a fee).

Checking the jack and wiring also applies if the phone works at one jack and not another.

If another phone works and the AT&T phone doesn't, check if the power adapter is plugged in and warm or cold. If the power brick is cold, then replace the power supply. The information on the type of power supply is usually listed on the bottom of the phone. Since this is a corded phone, it should work even without power, but sometimes, it won't. If the power is good to the phone, then replace the AT&T phone. Unless it's under warranty, it isn't worth getting them serviced. They aren't meant to be user serviced.

I hope this helps.

No caller ID. TP company says I have service.

  • Did you fully charge your phone? - Make sure you fully charge for 16-24 hours .

  • Is the battery old? - Replace the battery.

  • Is the electrical outlet switch turned on? - If you are using AC (electrical) power, make sure that the unit is connected to a non-switched electrical outlet.

  • Are the connecting wires tight - Unplug the AC power converter from the unit and plug it back in.

  • Do you have Caller ID service with your telephone company - In order to receive Caller ID records, you must subscribe to the standard name and number Caller ID service available through your local telephone company. If the Caller ID works for normal calls but not on Call waiting calls, then you must contact your phone company to get the combined CID/CW service.

  • Caller ID shows up after second ring - Be sure to wait until the second ring before answering. Caller ID signals comes through after the first ring, if caller pick ups phone too soon Caller ID signal will not be transmitted to the handset.

  • Confirm that caller ID is still working on that particular line by checking another phone on the same line - If Caller ID is not coming through contact your phone company provider.

If this does not fix your problem, contact your authorized Service Center.*

Only one ring with incoming calls from my Vtech and line is noisy. How do I solve this

Sounds more like a phone line problem than trouble with your phone. I suspect you have water in the line or some other problem that is causing trouble when the high ring voltage appears. Try disconnecting all phones and connect a plain old basic phone to one of your jacks. Better yet, if your house has a network interface jack on the outside, connect the phone there. Call your number and see if you still have the same trouble on the line. If so, call your phone company as the problem is in their wiring. If not, reconnect each phone in your house to see when the problem returns. Then you'll know which one is responsible.

Vtech model 2656 caller id is not working. How can I fix this?


Found this on the VTECH support site regarding your model:

Tip 1 of 1
Caller ID and Call Waiting ID are subscription services, available from most local telephone service providers. You must subscribe to these services in order for the features to work on your phone. Contact your local telephone service provider for more information.

In addition, your caller must be calling from an area that supports caller ID.

Both you and your caller’s telephone service provider must use compatible caller ID systems.

If you subscribe to DSL service for this telephone line, DSL filters must be plugged into EVERY phone jack that has a phone. The DSL signal can cause caller ID disruption, static, noise and other issues on your line. DSL filters block the high frequency DSL signals from being transmitted to the telephone. If you are not using the DSL filters provided by the telephone company, this will cause static/noise and possibly caller id issues on your phones.

In most cases, we recommend you connect the plug end of the DSL filter into the telephone jack, then connect a telephone cord between the filter and your phone.

Please contact your service provider to obtain DSL filters and installation information.

Caller ID and Call Waiting ID may not be available for every call. Common reasons are incompatibilities between your and your caller’s service, transmission errors and answering calls before the ID data is received.

In addition if you would like to contact them or get more info on your phone, then use this link:

How can I clear the previous registrations from the TRU 9485 base?

Use the following steps to reset the base to factory settings for all TRU models:

1. Disconnect the power from the base

2. hold down the following three (3) keys: [dnd] + [middle soft key] + [*]

3. While holding down the keys, plug in the base (hold the keys down until you hear a long beep).

According to Uniden Tech support, this is supposedly all it takes to reset the phone.

Locate phone away from devices which may interfere, basically anything with a transformer. Dont use long extension cords to connect phone to a wall jack that is far away. Plug ac power adaptor into spike-strip line filter like an isobar. Try another extension cord and/or a different location to see if you can isolate the cause of interference. Interference will get in 1 of 2 ways, through the phone line, or through the power supply.
