My mic doesn't work; callers can't hear me

Hi Ted,
I'm looking for a solution to a similar problem. I found this adapter that might help you: <http://www.theheadsetbuddy.com/pc-computer-headset-to-uniden-phone-adapter/>I can't vouch for it first-hand since I haven't used it but am about to purchase it. It looks like you should be able to use a headset or separate headphones and microphone with it.

call your provider or buy new phone

MAKE SURE THAT INSIDE THE HANDSET THE MODEL TCX905 SHOWS, IF IT SHOWS A DIFFERENT MODEL IT WILL NOT WORK.

try cleaning the mic' without openning the phone -
from the outside by an old touth brush...
that will do the trick

if you can open the screws without any damage
than pull out the mic's cover
it is probebly full of moist

Is your mic on your headset muted?

What is the model # of your handset. It must be tcx 900 or tcx 905 to be compatible with the tru 9488. Good luck! :)

i had to delete the caller id which was full. everything works now.

It worked well for me too! Thanks Fixya.com!! I was told I had to buy a new phone because the microphone went back. Took the receiver apart (4 screws in back of handset and 2 that held the board in place), cleaned mic with alcohol and a q-tip, and removed the rubber piece that kept the mic clean (inside of the housing), and presto, it worked just fine. The ribbon cable came loose upon opening up inside of phone, but I stuck it back inside the top of base and I was ready to go.
