AT&T EL52303 Cordless Telephone User Manual

I cannot dial out.
First try all the suggestions in the item I cannot get a dial tone above.
Make sure you have a dial tone before dialing. The cordless handset may
take a second or two to find the telephone base and produce a dial tone.
This is normal. Wait an extra second before dialing.
Check that all the telephones connected to the same telephone line are
hung up.
Make sure to set the dial mode to the correct setting (pulse dialing or tone
dialing) for the service in your area (see Battery installation and charging
on pages 7-8).
Eliminate any background noise. Noise from a television, radio or other
appliances may cause the telephone not to dial out properly. If you cannot
eliminate the background noise, first try muting the cordless handset
before dialing, or dialing from another room with less background noise.
If other telephones in your home are having the same problem, the
problem is in your wiring or telephone service. Contact your telephone
service provider (charges may apply).
My cordless handset isn’t performing normally.
Make sure the power cord is securely plugged into the telephone base.
Plug the power adapter into a different, working electrical outlet not
controlled by 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 to your cordless telephone. Try installing your
telephone as far away as possible from these types of electronic devices.
