Troubleshooting
The display shows No home line. I cannot get a dial tone.
Try all the suggestions mentioned above.
f
If the previous suggestions do not work, disconnect the
f
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
f
telephone line cord may be defective. Install a new telephone
line cord.
If changing the telephone line cord does not help, the wall
f
jack (or the wiring to this wall jack) may be defective. Try using
a different wall jack in your home to connect your DLP73290/
DLP73390/DLP73490/DLP73590 telephone, or contact your
telephone service provider (charges may apply).
I cannot dial out.
Try all the suggestions mentioned above.
f
Make sure you have a dial tone before dialing. The handset may
f
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
f
other appliances may cause the phone to not dial out properly.
If you cannot eliminate the background noise, first try muting
the handset before dialing, or dialing from another room in your
home with less background noise.
Disconnect the telephone base from the telephone wall jack and
f
plug in a working telephone. If the other phones 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).
