Question about Uniden DCT646-3 Cordless Phone

1 Answer

Message waiting flashing light

The light continues to flash even after I have cleared all the messages in memory. The only way I have been eliminating the flashing light is to unplug it. It used to clear itself. My unit is a DCX640

Same problem. We have a Panasonic set on the other half of the same line, it updates correctly when messages are cleared. We thought updating our voicemail system to unified messaging would take care of it--no go, the three Uniden DCT646-3's we have do not update and clear the message notification. Thank you.

Find a copy of the manual. If you hold down the page button on the main unit for about 5 sec until it stops beeping 9usually beeps a triple signal twice out to all handsets, it clears the voicemail notification. Since the phone does not support our voicemail system (requires SDT) we use another brand of phone in the household for our voicemail notifications (a quality phone brand), and turned it off on the Unidens. That's the best we can do, given the lack of completely finished engineering put into these models--but that's what you get for the price.

Flashing red light, like I have a message waiting, however I have cleared all messages and it still flashing red. Uniden DECT 6.0


Does your phone service provide you with a voicemail box? If so, you likely have a message waiting for you on your voicemail inbox.

My phone flashes all the time, and gives me an indication that I have a message. There is no message, and it continues to blink, even after it is supposedly cleared out.


My message light is lit SOLID and only follows the ring, so you must be talking about the FWD/DND light.

The Forward condition can be cleared, but you will lose the call forwarding to voice mail. The light can be programmed by your installer to be solid, instead of flashing, but the installer will have to do that.

If you're somehow oddly talking about the message indicator on the upper right of the phone which doesn't flash, them press MESSAGE and look at the display. It will tell you where the message came from and let you press CLEAR to erase it.

Red message light flashing


The term we used for this back when I worked for the phone company was a "stuck message waiting indicator" and the way to fix it was:

Call yourself and leave a message.
Hang up and wait 2 minutes (we used to say 5 minutes, but 2 is plenty)
Retreive/delete your voice mail message
Hang up and wait 2 minutes


That should clear the blinking light.
