AT&T CL80101 Cordless Telephone User Manual

If there is no dial tone on that other telephone either, your
telephone line cord may be defective. Install a new telephone
line cord.
If changing the telephone line cord does not help, the wall
jack (or the wiring to this wall jack) may be defective. Try
using a different wall jack in your home to connect your
CL82501/CL82551/CL82601 telephone, or contact your
telephone service provider (charges may apply).
I cannot dial out.
Try all the suggestions mentioned above.
Make sure you have a dial tone before dialing. The cordless
handset might take a second or two to find the telephone base
and produce a dial tone. This is normal. Wait an extra second
before dialing.
Eliminate any background noise. Noise from a television, radio or
other appliances might cause the phone to not dial out properly.
If you cannot eliminate the background noise, try muting the
cordless handset before dialing, or dialing from another room
with less background noise.
If other phones in your home are having the same problem,
contact your telephone service provider (charges might apply).
My cordless handset isn’t performing normally.
Make sure you plug the power cord securely into the telephone
base. Plug the power adapter into a different, working electrical
outlet without a wall switch.
Move the cordless handset closer to the telephone base. You
might have moved out of range.
Reset the telephone base. Unplug the electrical power. Wait for
15 seconds, then plug it back in. Allow up to one minute for the
cordless handset and telephone base to reset.
Other electronic products such as HAM radios and other DECT
phones, can cause interference with your cordless phone. Try
installing your phone as far away as possible from these types
of electronic devices.
