order they are registered (up to HANDSET 12).
You must register each handset separately. When first purchased, all
expansion handsets show To register, see manual.

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
CL82311/CL82321 telephone, or contact your telephone
service provider (charges may apply).
I cannot dial out.
Try all the suggestions mentioned above.
Make sure you have a dial tone before dialing. The cordless
handset might 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
other appliances might cause the phone to not dial out properly.
If you cannot eliminate the background noise, try muting the
cordless handset before dialing, or dialing from another room
with less background noise.
If other phones in your home are having the same problem,
contact your telephone service provider (charges might apply).
My cordless handset isn’t performing normally.
Make sure you plug the power cord securely into the telephone
base. Plug the power adapter into a different, working electrical
outlet without a wall switch.
Move the cordless handset closer to the telephone base. You
might have moved out of range.
Unplug the electrical power. Wait for 15 seconds, and then plug
it back. Allow up to one minute for the cordless handset and
telephone base to reset.
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.

I get noise, static, or weak signals even when I’m near 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 as
a result of DSL interference. Please contact your DSL service
provider for more information about DSL filters.
You may be able to improve the performance of your cordless
phone by installing your new telephone base as far as possible
from any other existing cordless telephone system that may
already be installed.
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.
Do not install this phone near a microwave oven or on the same
electrical outlet. You might experience decreased performance
while the microwave oven is operating.
If you plug your phone in with a modem or a surge protector,
plug the phone (or modem/surge protector) into a different
location. If this does not solve the problem, relocate your phone
or modem farther apart from one another, or use a different
surge protector.
Move your phone to a higher location. The phone might have
better reception in a high area.
If the other phones in your home are having the same problem,
contact your telephone service provider (charges may apply).
I experience poor sound quality when using the speakerphone.
For increased sound quality while using the speakerphone, place
the handset on a flat surface with the dialing keys facing up.

My cordless handset does not ring when I receive a call.
Make sure that the ringer is not off. Refer to Ringer volume
in the user’s manual provided with your CL82311/CL82321
telephone.
Make sure you plug the telephone line cord securely into the
telephone base and telephone jack. Make sure you plug in the
power cord securely.
The cordless handset may be too far from the telephone base.
Charge the battery in the cordless handset for at least 10 hours.
For optimum daily performance, return the cordless handset to
the telephone base or charger when not in use.
You may have too many extension phones on your telephone
line to allow all of them to ring simultaneously. Try unplugging
some of the other phones.
The layout of your home or office might be limiting the
operating range. Try moving the telephone base to another
location, preferably on an upper floor.
If the other phones in your home are having the same problem,
contact your telephone service provider (charges might apply).
Test a working phone at the phone jack. If another phone has
the same problem, contact your telephone service provider
(charges might apply).
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.
Completely remove the battery. Replace it and place the
cordless handset into the telephone base. Allow up to one
minute for the handset to reestablish its connection with the
telephone base.
