Question about Uniden DCT646-3 Cordless Phone
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!
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.

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.
