cancel, by pressing the desired handset

number. i #
5 "Yes" i # i {ih}
Base Station:

A handset can be registered to a maximum

of 4 base units. A handset can cancel a base

handset to "forget" the base unit.

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.

Short answer:
No. This model of phone can only support 4 handsets. If you need more than that, you will need to have a second base unit.

Detailed answer:
One of my handsets went bad, and I just bought complete DCT748-4 package from a seller on eBay for a very good price. This set was used, but in very good condition. I didn't need the whole set - just one handset - but like I said, it was a good price. Anyway, I began by telling my old base unit to de-register handset #2 (the failed unit). However, I then found that I could not register the "new" handset with my old base unit because it was already registered to the "new" base unit. So, I first had to apply power to the "new" base unit and de-register the handsets. Then, I placed one of the "new" handsets onto my old base unit, and it said "Handset Registering ..." and registered just fine. Just for the fun of it, I placed one of the other spare handsets into my old base unit. It said "Hanset Registering ..." but then it beeped and said "Registration Failed." This is because I already had 4 handsets registered to my base, and the base can not handle a fifth handset.
