Troubleshooting
There may be too many extension phones on the telephone line to allow all of them to
ring simultaneously. Unplug some of them.
If other telephones in your home are having the same problem, the problem is in the
wiring or local service. Contact your telephone service provider.
Other electronic products such as HAM radios and other DECT phones can cause
interference with your cordless phone. Try installing your phone as far away as possible
from these types of electronic devices.
Test a working telephone at the telephone wall jack. If another telephone has the same
problem, the problem is in the telephone wall jack. Contact your telephone
service provider.
The telephone line cord may be defective. Install a new telephone line cord.
Remove and install the battery again, and place the handset in the telephone base
or charger.
Wait for the handset to synchronize with the telephone base. Allow up to one minute for
this to take place.
My handset beeps and is not performing normally.
Make sure the power cord is securely plugged into the telephone base. Plug the
telephone base into a different working electrical outlet not controlled by a wall switch.
Move the handset closer to the telephone base. It may be out of range.
Reset the telephone base by unplugging the electrical power to the base. Wait for 15
seconds and plug it back in again. Allow up to one minute for the cordless handset and
telephone base to synchronize.
Other electronic products such as HAM radios and other DECT phones can cause
interference with your cordless phone. Try installing your phone as far away as possible
from these types of electronic devices.
There is interference during a telephone conversation. My calls fade out
when I am using the cordless handset.
The handset may be out of range. Move it closer to the telephone base.
If you subscribe to high-speed Internet service (DSL - digital subscriber line) through
your telephone line, you must install a DSL filter between the telephone line cord and
the telephone wall jack. The filter prevents noise and caller ID problems caused by DSL
interference. Contact your DSL service provider for more information about DSL filters.
Appliances or other cordless telephones plugged into the same circuit as the telephone
base can cause interference. Try moving the appliance or telephone base to
another outlet.
