No manual and am receiving unwanted calls at night

Using Call Block
If you subscribe to Caller ID, you can save phone numbers to the call block list. When a call comes in, the phone compares the received phone number to the numbers on the call block list. If the phone number is on the list, the phone replaces the caller's name with Call Blocked and disconnects the call. (The caller hears a reject tone.)

The call block list holds 20 entries, and all stations share the same list. You can add entries through the Call Blocking menu, by selecting Add Call Block in the CID menu, or by blocking incoming calls. (Only one station can edit the call block list at a time.)

Blocking incoming calls

  1. When the phone rings, wait until the display shows the Caller ID information (usually after the second ring).
  2. If you want to block the call and add this number to the call block list, press Block.
  3. When the phone asks you to confirm, press Menu/select or Block. Blocking an incoming call from an "Unknown" or "Private" number is the same as selecting Unknown Number or Private Number from the Call Blocking menu.
Call Blocking menu options
  1. With the phone in standby, open the menu and select Call Blocking.
  2. Choose one of these options:
  • Create New(Handset only) - Add an entry to your call block list. The phone will prompt you to enter a name & phone number.
  • Private Number(Handset only) - Block all calls from numbers reported by CID as "Private." (This does not count as one of the 20 entries.)
  • Unknown Number(Handset only) - Block all calls from numbers reported by CID as "Unknown". (This does not count as one of the 20 entries.)

Call block entry options
  1. With the phone in standby, open the call block list and find the entry you want.
  2. Press Menu/select to open the individual entry menu. Choose one of these options:
  • Edit(Handset only) - Edit this entry. The phone will prompt you to edit the name & phone number.
  • Delete - Erase this entry from the list & allow calls from this number.

Uniden EZX290 Expansion Handset Fails Registration to Uniden D1660 Base Unit

Unfortunately, handsets are not universal for Uniden cordless phone systems. The accessory handset for the EZX290 is compatible with the DECT1500, 2000, 2100, 300 and 2900 DECT 6.0 phone systems. The accessory handset for the D1660 is here: https://www.amazon.com/Uniden-D1660-DECT6-0-Cordless-Handset/dp/B004NEUIY2 . I wish that I had better news for you. Unfortunately, the two systems (EZX290 and D1660) don't use same handshake codes. Cindy Wells

Can I add another uniden hand set to a uniden D1680 series

The Uniden D-1680 system can have up to 12 handsets registered to the base. (The phone system was sold in bundles with 0 to 11 accessory handsets.) However, this cordless phone system has been discontinued. I can only find used DCX160 handsets (the compatible accessory handset) on Amazon and E-bay. I hope this helps. Cindy Wells

Sync 2 versions of Uniden Dect 6.0 to work off the same base.

Yes, you can join an older and a newer version of Uniden Dect 6.0 cordless phones to work off the same base. Here are the steps to sync them:
  1. Disconnect the power cord from the base of both phones.
  2. Take the battery out of each handset.
  3. Wait for a few minutes.
  4. Reconnect the power cord to the base of the newer version phone and insert its battery.
  5. Wait for the phone to register on the base, which should take a few seconds.
  6. Once the newer phone has registered, repeat steps 4 and 5 with the older version phone.
  7. The older version phone should now register on the same base.
  8. Test the phones to make sure they are working properly.
If for some reason the phones do not register on the same base, refer to the instruction manual that came with the newer version phone for further troubleshooting steps.

My mother has a Uniden SS E45 +1 phone and it keeps flashing but there is no message. How do I fix it for her?

It may be that the message is held by the Telco. Phone the supplier and ask. You dial in with a special number and PIN.

A uniden phone DECT 6.0. how do i turn on call waiting

Talk to your telephone service provider. There will be a fee. Cindy Wells (Uniden landline phones can make or receive calls; some models have a answering system. Most current models can even check if you have messages on the telephone provider's voice mail. (Sometimes, they'll give spurious voice mail information.) However, they don't have any built-in way of seeing any data (another call) from the telephone provider when the phone is in use.)

DCX170 handset will not register to DECT2060 Base

Yes, it looks they are compatible. I would guess you need to set up from scratch. Remove all power to base unit and handsets, batteries to handsets, and phone line and start from the Base unit, to powering handsets again. https://www.google.com/search?q=DECT2060+base%2C+with+DCX170+handset ..

How to register a new handset?

Unfortunately, the EXI5560 is not an expandable cordless telephone system. The base can only use the handset to which it was originally linked at the factory. Similarly, the DXA15588 handsets need to be paired to that base, not just to any Uniden cordless phone base. The first handset gets registered while it is charging in the main base. Charge the second handset fully in the charging base. Make sure not to use the phone for any incoming calls during the registration process. Take the first handset off the main base. You do not have to put this handset on the other charger and put second handset on the main base. Wait for the Charge/In Use LED to begin to flash. Wait at least another 5 seconds before removing the second handset from the main base. That's when you should be able to use the find HS button on the DXA15588-2 main base to get both handsets to beep. I hope this helps. You can find the manuals for these phones at the following sites: https://www.uniden.info/download/ompdf/EXI5560om.pdf and https://www.uniden.info/download/ompdf/DXAI5588-2om.pdf . Cindy Wells
