Troubleshooting
My calls fade out or cut in
and out when I am using
the telephone.
The sound quality of the
headset is poor
I hear other calls when
using the telephone.
• If you have a headset plugged into the telephone,
try unplugging it and firmly plugging it in again.
• Disconnect the telephone base from the
modular jack and plug in another corded
telephone. If calls are still not clear, the problem
is probably in the wiring or local service. Contact
your local service company (charges may apply).
• If you are using the speakerphone when this
problem occurs, eliminate any background noise.
Noise from the television, radio, or other appliances
may cause the speakerphone to cut in and out.
Try engaging the [MUTE] button when you are not
speaking or eliminating the background noise.
• If you subscribe to DSL service, you need to
have a DSL splitter installed. See Important
information for DSL users section on page 6 in
this manual.
• If you have DSL service, and you have more than
three telephone sets, and you have installed
microfilters, you may need to have a DSL splitter
installed by your DSL service provider.
• Unplug it and firmly plug it in again.
• Disconnect the telephone base from the telephone
jack. Plug in a different telephone. If you still hear
other calls, the problem is probably in the wiring
or local service. Call your local telephone company.
• Make sure you are using the round black cords
that came with the phone. These cords help
prevent crosstalk (hearing other calls).
