Uniden TCX 905 Cordless phones. Nav Key has stopped working on all 3 of my hand units. How can I fix this? Seemed to happen all at the same time.

Hope this helps. Thanks for using FixYa.

You have unheard messages on the voicemail system provided by your telephone company. This system records messages when someone calls while you're already on the phone. Please contact your telephone company for instructions on accessing their voicemail system.

There's a user's guide at http://www.uniden.com/pdf/DECT2185om.pdf

If you are not too far away-not "out of range" then try rehoming/pairing the handset with the base unit. You probably need the phones together to do this. Your manual will explain how-it will have been done in the original setup.

MAKE SURE THAT INSIDE THE HANDSET THE MODEL TCX905 SHOWS, IF IT SHOWS A DIFFERENT MODEL IT WILL NOT WORK.

It is possible that you have maxed all of the headsets that can connect to the base. Yes, the base can support 10 headsets, but there is a small chance that in some way you registered more to the base or you purchased a base that had phone registered to it that are not in your possession. Either way, if the base is maxed out, you will not be able to register any additional headsets to it. The only option is to do a factory reset of the base unit if this happens to be the case. This is done as follows according to Uniden Tech Support:

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). This is supposedly all it takes to reset the phone.

The way to determine the number of hand sets tied to the phone is to press the intercom key on the base and scroll through the list of phones. if you see more than the number you anticipate still being tied to the base, you will have to utilize the above procedure.

I don't have the answer but have the same problem. Uniden tech support had me disconnect power, etc. to no avail. Next solution was "replace the unit". I'm looking for a two-line phone with no answering device - use voice mail. Any ideas?

SOLUTION:

1. First, remove the battery cover on your unregistered TCX905 and look under the battery to confirm that you indeed purchased a TCX905 because some Uniden handsets were packaged as 905's but were not.

2. Take the fully charged unregistered 905 to the base unit TRU9496.

3. On the TRU 9496 base unit press "Menu" then select "Registration" and press OK

4. You should get the message "press the # key on the remote handset".

5. Depress the "#" key on the unregistered 905 and it should register.

What is the model # of your handset. It must be tcx 900 or tcx 905 to be compatible with the tru 9488. Good luck! :)

I just successfully registered 4 TCX905s with my TRU8865 base - it's documented in the TCX905 manual.

Be sure the handset you want to register is fully charged.

Remove the handset you want to register from its charger.

Now unplug the AC for the main base, hold down the 'find handset' key on the base and plug the AC in again, when it beeps, you can let go of that button.

Hold down the '#' on the handset you want to register, it will show 'Registering Handset...' and when it beeps, it's done - registered, you're good to go :)
