My telephone doesn't work at all.
• Make sure the power cord is securely plugged in.
• Make sure you plug the telephone line cord securely and firmly into the
telephone and the telephone wall jack.
• Reset the telephone. Unplug the electrical power. Wait for approximately
15 seconds, then plug it back in. Allow up to one minute for the telephone
to reset.
The display shows No line. I cannot get a dial tone.
• Try all the suggestions, as mentioned above.
• If the previous suggestions do not work, disconnect the telephone line
cord from your telephone and connect the telephone line cord to
another telephone.
• 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 CL4940 telephone, or contact your
telephone service provider (charges may apply).
I cannot dial out.
• Try all the suggestions, as mentioned above.
• Make sure you have a dial tone before dialing.
• Eliminate any background noise. Noise from a television, radio or other
appliance may cause the phone to not dial out properly. If you cannot
eliminate the background noise, first try muting the telephone 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 may apply).
I hear other calls while using my phone.
• Disconnect the telephone from the telephone jack, and plug in a different
telephone. If you still hear other calls, call your telephone service provider.
System announces, "Time and day not set."
• You need to set the system clock (page 10).
