Question about Uniden DCT646-3 Cordless Phone

2 Answers

My DCT646-2 no one can hear me.

I have a very similiar problem with this post. Both my phones did the same thing. I unplugged the batteries and the bases. When I plugged everything back in my 646-1 started working again but my 646-2 still doesn't. It will ring, show the caller ID and I can hear the person but they still can't hear me. Help please!

    Same problem here. I've never had many issues with other uniden phones but this has happened to three of my 646's. I then bought a dcx750 (feels like it hasn't even been a year but could be wrong) and yesterday the button panel stopped completely working. It lights up and rings when a call comes in but I can't answer or dial, nothing.

    Extremely disappointed and I'm down to 1 phone so it might be time for a switch.

Take it apart and clean the mic with alcohol. (I took out a black round cover it had on top to reduce eco)
Worked for me.

cheers,

We had similar problem with XS916 dual cordless models, first one handset went extremely faint for external audio output, then just recently the other handset went exactly the same way, making both pretty well inoperable. Found this blog suggestion worked well, took both units apart (2 micro screws under batteries, then a further 5 inside), took rubber protector off microphone at bottom of unit, gave clean with small art type paint brush & methylated spirits, carefully put back together, both units now work fine as new.

When we are talking to someone they say they can`t hear us


Today, Nov 5, 2011, we had the same problem. I put the handsets in the bases and unplugged the power cords from the outlets. Then I opened the battery compartments and unplugged the batteries. I then replugged the power cords and put the batteries back into the handsets. I put the handsets back onto the bases and waited for a couple minutes. Then reprogramed the date and time on the # 1 handset. I then placed a phone call to an outside phone and VOILA! They could hear my voice! Hope this helps Earl Sealy even though it is sorta late.

Welcome to FixYa.

Reset the units/set up by doing the following:
  • Turn OFF all the HANDSETS.
  • Remove the batteries of the HANDSETS.
  • Unplug the power source of the BASE.
  • Unplug the phone line of the BASE.
  • Let it stay that way for 30 mins.
  • Insert the battery again of the HANDSETS, make sure it is charged properly.
  • Plug back the power source of the BASE.
  • Plug back the phone line to the BASE.
  • Register any handset that is unregistered (refer to manual).


Keep me posted.

It is likely your phone has a mouthpiece or ear piece problem that is why the reciver can't hear you.So your need to take the phone to the nearest repair office for it to be changed.

I can't hear any sound on my verizon wireless razzle phone. It just stopped working after i plugged in headphones what is wrong with my phone?


I had this very same thing happen to me yesterday after listening to music with my headphones. After unplugging them, the speaker would no longer work nor the speakerphone.

After trying many things without success, I was finally able to resolve this by plugging back in the headphone cable and pushing the jack around a little bit to the side until I could hear sound.

I did this while trying to place an MP3 just to make it easier. So far this has worked fine. But now I am reluctant to use the headphones any more.
I know your post was several months ago so this may or may not be helpful.

I cant hear anyone nor can they hear me during a phone call


Once water gets inside the phone there is not much you can do about it. If you want you can try what I have done for my daughter many times with good results. Remove the battery, this will help a great deal. Just having the phone powered up is not a good thing while it is wet. After removing the battery allow it to air dry, you can use a hair dryer to speed things up, but be careful not to get the phone too hot. I hold it in my hand and that keeps me from getting it to hot.
Leave the battery out for as long as you can, days would be better than hours. Then put the battery back in and see if the moisture is out of the phone. If this works you are good to go, if not then your phone may be beyond help because of the water.


I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread.

Vtech cordless phone appears to be mute


Try the "hard reboot". /1/ Unplug power from base station. /2/ Disconnect battery in each handset. /3/ Wait a few minutes. /4/ Reconnect battery. /5/ Re-plug-in power to base station. /6/ Place handset in base station, and wait a few minutes for it to recover.
You may have to reset time/date and/or the handset ##.

Phone is Locked on headset setting even though there is no headset connected


best thing to connect a headset and take it out, that will trigger the function that it will come back to handset.

Good Luck
