My telephone does not work at all.
• Make sure the power adapter is securely plugged into an electrical outlet
not controlled by a wall switch.
• Make sure you plug the telephone line cord securely and firmly into the
telephone jack and the telephone wall jack.
• Unplug the power adapter from the electrical outlet. Wait for
approximately 15 seconds, then plug it back in. Allow up to one minute for
the telephone to reset.
• You may need to purchase three AA alkaline batteries as backup batteries
to make the telephone work in the event of a power failure. Please refer
to optional backup battery installation on page 4 in this user's manual.
• Disconnect the telephone base from the telephone wall jack and plug in a
working telephone. If that telephone does not work, the problem is probably
in the wiring or the telephone service. Call your telephone service provider.
The display shows LX:No LINE. I cannot get a dial tone.
• Try all the suggestions, as mentioned above.
• Make sure you plug the handset cord securely and firmly into the handset
jack on the telephone base and the corded handset.
Make sure hoLD is not pressed.
•
• If there is no dial tone when the hEADSET key is pressed, make sure a
corded headset is firmly connected in the headset jack.
• If you are only using one telephone line, make sure to set it as the primary
line (see Set the primary line on page 18).
• 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 ML17939 telephone, or contact your
telephone service provider (charges may apply).
I cannot dial out.
• Try all the suggestions, as mentioned above.
• Make sure there is a dial tone before dialing. The telephone might take a
second or two to produce a dial tone. This is normal. Wait an extra second
before dialing.
