20 Most Recent Uniden DECT 6.0 Cordless Phone ID Questions & Answers

I'm having the same problem as you are. My screen went blank for no apparent reason. I've been searching for a quick fix solution but I keep comming across asinine answers that has nothing to do with the original problem such as this one. If you find a solution before I do, can you please post it? Thanks in advance!

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.

UNIDEN MODEL EZX290 HANDSET>>>VISUAL RINGET AT TOP (YELLOW LED) FLASHES. HOW DO I TURN THT OFF?

Since you didn't specify the model of your Uniden DECT 6.0 phone I can only suggest you select it from the list beginning here to download a copy of the manual.

For the Uniden DECT 6.0 6035 system... Setting a Security Code or Personal Identi?cation Number (PIN) To play your messages from a remote location, you will need to enter a two-digit security code or Personal Identi?cation Number (PIN). The default security code is 80. To change the PIN: 1) On the handset, press [Menu/Select]. Select the ANSW. SETUP menu, and then the SECURITY CODE submenu. 2) Use the number keypad ([0] through [9]) to enter a two-digit security code (00-99). 3) Press [Menu/Select]. You will hear a con?rmation tone. Here is the manual: Uniden 6035 1 Owner Manual

This works for the Uniden D1660 and similar dect 6.0 models: On the lower right corner of the keypad, press the # [silent] key. One press put it into 'silent mode', another press takes it out. Good luck!
