Uniden Have problem

First make to get a compatible handset.

For the Uniden D1660-2, the compatible handsets are DCX160 and DWX337. Make sure that you have not exceeded the number of handsets that the phone can support. The D1660-2 can support 12 handsets unless you use any DWX337 handsets. Then the limit is 6. (If you have more handsets, you will need to deregister some of them first.) Then allow the handset to charge. If the handset is reading "not registered", then place it into the base unit. You should see "Handset Registering" for about 30 seconds; then it will read Registration Complete. The manual for the Uniden D1660-2 is available here: http://www.uniden.com/content/ebiz/uniden/resources/ownersmanuals/D1660-2om.pdf . This is the most common Registration for Uniden phones; there are a few exceptions (depending on the base or the replacement handset). Check the appropriate manual (see below to find the manuals).

For the DECT4096, press Menu on the base and then navigate to Handset Register. When you see Handset Registering on the base display, press and hold # on the handset to be registered until you see Handset Registering. (It takes about 2 seconds.) After the display changes to Handset Registered, check for dial tone.

On a few Uniden phones, there is a Page/Handst Register button on the base. On those you navigate through the Handset menu to Handset Register (Menu > Handset menu > Handset Registration). Then press and hold the Page button until you hear a beep. Then wait for the registration to be completed.

Most Uniden manuals are available here: http://www.uniden.com/scat/cordlessphones_mnl . Select your type of Uniden phone and scroll through the list to your model or use the search box to directly search for your phone and the manual.

I hope this helps.

Welcome to Fixya
Dear USer
Place your Extension Phone Near to Main for Few times Until it Beeps.OR it Ask for Registration like Please Register or Something like that.Follow the Steps carefully to Register it...Then Check it for Dial tone to Confirm.Some phones may display that the handset needs to be registered. If this appears-Move the handset near to base/main unit & press the "Prog/Mute". Next, press the "Pager" button on the base unit .Then press the "Prog/Mute" button on the handset again to complete the registration.
Hope you got it....Thanks for Connecting FixYa

I had a similar problem which I finally fixed. You did not say if any of your phones registered.
First try the following recommended by Uniden Support:
Your phone(s) should be fully charged before putting them on the main base.
Unplug the battery from the phone by removing the battery cover and removing the connector. Then, push the # and * key together and hold while you plug the battery back in (requires some dexterity). Continue to hold the two keys until you hear a confirmation tone. This will force the phone to reregister. Put the phone on the main base (if you are sure it has a fully charged battery) and see if it will reregister it to solve the problem.
That did not work for me. So, I followed the instructions to de-register the handset (even though it hadn't really registered). But, I also pretended like the Base was not available (because using the base in this step also failed).
1) Press and hold the hang up and # keys for at least 5 seconds.
2) Move the cursor to select Base Unavailable and then press Select.
3) Select the base you want to deregister from, press Select and then move the cursor to Yes and select.
This causes the phone to delete any of its base information.
At this point, again insure that your phone shows the battery is fully charged and if it is not, put it on the stand alone charger base (not the main base). With the battery fully charged, place it on the base and try registering again by placing it in the main base.
If neither of these approaches help, contact support at Uniden.com.
However, my problems were cleared when I cleared the handset with the second set of instructions.

The DXI4286-2 is an Analog phone, it does not allow for both handset to be used at the same time. You can transfer a call from one handset to another, but cannot talk on both at the same time.
The following is from the user's manual for your phone:

Unavailable message is displayed
on the LCD screen of the
handset.
• Make sure the other handset is not already in use. Both handsets cannot be in talk mode at the
same time.
• Place the handset in the main base for at least 5 seconds to re-register to the main base.
• Make sure the handset is not too far from the main base when trying to use.

You might want to try one of the DECT or a Digital 2.4 or 5.8 GHz phones, they allow you to use multiple handsets at the same time.

What that means is after you plug in the base set the #1 handset into the base charger for a few seconds, then put #2 handset into the base charger that registers it to that base at your house. continue on through the rest of them if you have more than 2 , They only need to be in the base for about ten seconds, then it should or might say registered on the screen,,Good Luck

Here it is step-by-step: 1. Remove battery

2. Hold down the * and # buttons and reinsert battery. You should hear a long beep. If not retry. (This is a bit awkward but hold the handset upside down and it’s workable)

3. Screen will be blank. Immediately press the right soft menu button.

4. Screen will report that EEPROM is clearing and then state EEPROM Clear Ok

5. Remove battery (yes again)

6. Reinsert battery (this time there’s no need to hold down any buttons)

7. Handset will reboot with Welcome screen and then state that phone must be registered (this is the status a handset should be in from the factory)

8. Place handset on base and it will register as normal

You need to register the new handset with the base.
In Global settings De-register the new handset then place it on the main base unit connected. It should then register.

You can unregister your phone without being in the cradle, but to re-register them, just put them back in the cradle.  After being unregistered, they will automatically re-register once they are put back in the cradle of the main base.  Try setting them back in the base cradle to re-register, and hopefully that will work for you.

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.

Only one handset can be registered at a time.
