Troubleshooting
Display screen is blank.
My calls cut in and out
when I am using the
telephone.
The sound quality of the
headset is poor.
The system does not
receive caller ID or the
system does not display
caller ID during call
waiting.
• Make sure the power cord is connected to both
the phone and an electrical outlet not controlled
by a wall switch.
• 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 might cause the speakerphone to
cut in and out. Try pressing the [MUTE] button
when you are not speaking or eliminate the
background noise.
• If you have DSL (digital subscriber line) 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.
• Make sure you subscribe to caller ID with call
waiting features services provided by the local
telephone company.
• The caller might not be calling from an area that
supports caller ID.
• Both you and the caller's telephone companies
must use equipment that are compatible with
caller ID service.
• If your phone is currently in use and a new call
comes in, you must press the [ ] to see the
new call. This procedure enables you to see call
waiting caller ID and caller ID from other lines
on the phone.
• Make sure the telephone line cords were
provided with the telephone.
