20 Most Recent Uniden TRU8885-2 Cordless Phone - Page 3 Questions & Answers

if the non-cordless phones are ok, it sounds as if the cordless handsets are the only ones not working, have you charged the batteries on those handsets ok and are there any signs if life, eg lights or on-screen messages ? Are they switched off ?
If there are signs of life, check the level of charge, if dead completely, take it/them to the main unit and put on charge for about 10 hours, if they work for only a short time and you have had the phones for a few years, then you will need to replace the re-chargable cells as they don't last forever and they are not holding the charge.
Hope this has given you some clues.....

Many people confuse voice mail with answering machines. Most of the time if you have voicemail that is provided by your phone company you will hear a stuttered dial tone when you pic up the reciever. If this is what you hear you should call the service provider and they will explain how to retreive your messages and delete the old ones. Are you able to listen to you messages? If you have voice mail, you do not need the answering machine turned on on your phone.

one thing you could check immediately is the filter, they do go faulty sometimes, just swop it with another one that you know is a good one.

Here is a link to Uniden's site, and on the right side of the page, there is a link for a download manual pdf and helpline
http://www.uniden.com/products/productdetail.cfm?product=TRU8885-2

also worth checking if any buttons are stuck, or if the handset is set to pulse rather than tone mode, or if it has had a tumble or knock, possibly the keypad connector has come loose .

Hope this helps.

could there be interference ?

Severe noise interference.
• Keep the handset away from microwave ovens, computers, remote control toys, wireless
microphones, alarm systems, intercoms, room monitors, fluorescent lights, and electrical
appliances.
• Move to another location or turn off the source of interference.

Or maybe the unit is recording the calls, this is accompanied by an alert tone or click.

Here is a helpful link to the uniden site, including the manual download pdf and helpline number, as you can see, spares are readily available, including batteries ( first check the battery connections and give a long charge 10 hrs ) good luck !

Here are sample paragraphs from the user manual : hope it helps !

The new message LED on the handset flashes when you have new messages in your
answering system. The LED stops flashing when all new messages are played back.

3) To delete all messages, press delete messege in standby mode. Press delete
messege again after the announcement "To delete all messages, press delete
again."
When you try to delete all messages without first listening to your new messages,
you hear several short beeps followed by an announcement "Please playback all
messages." This protects you from accidentally erasing messages you have not yet
reviewed.
Important:
When you press delete messege, you are permanently deleting the message. Once
deleted, the message cannot be replayed or retrieved.

Here is a link to the uniden manual link and an excerpt from the manual section which deals with your problem :

I have searched the user manual and can find no help on this matter, although there are help numbers listed and I'm sure they can advise, here is the link to the main page and there is a link to a pdf manual download if you don't already have one http://www.uniden.com/products/productdetail.cfm?product=TRU8885-2

However, it may be that you could use a T adaptor or socket doubler on the line jack and plug both in. good luck !

I have found a link on the uniden site for you and the replacement handset comes complete with a new battery !

Are both cordless handsets used with the same main line ?

it depends on where you live and what telephone company you are with...you will need to contact your telephone company and ask for the temporary ( call by call ) caller rejection unblocking code.( eg the code will be different in the UK compared to say the USA ) Please note that this will reveal your number to the called party thus enabling the call to go through. ( assuming you have your number permanently withheld as is implied by your comments )

Hope it helps.

This sounds like the register-deregister problem elsewhere on this page. Try holding down the "end" and "#" buttons for about 6 seconds to deregister the phones and then reregister them. I had this problem too and it worked for me.

Page 61 from the Base Unit, there is Delete All. From the handset you have to delete 1 at a time.

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

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
