Adding and registering handsets
Before using a new TL90071 handset, you must register it with 
an AT&T TL92271/TL92371/TL92471/TL96271/TL96371/TL96471 
telephone system (purchased separately). These telephone 
systems can support up to 12 handsets.
The handsets provided with your telephone system are already 
registered as �ANDSET 1 and so forth. Additional handsets 
registered to the telephone system are assigned in the 
sequential order they are registered (up to �ANDSET 12). 
You must register each handset separately. When first purchased, 
all expansion handsets show Put handset on �ASE to register. 
Register a handset to your telephone base  
(for AT&T models TL92271/TL92371/TL92471)
1. Make sure the handset is out of the telephone 
base or charger and shows Put handset on  �ASE  
to register before you begin registration.
2. Put the handset you wish to register on the 
telephone base cradle, not the charger.
3. The handset displays Registering handset... 
on the handset and the red IN �SE light on 
the telephone base turns on. It takes about 90 
seconds to complete the registration process. 
The handset displays �ANDSET X Registered  
(X represents the registered handset number).  
The IN �SE light turns off and the handset  
beeps when registration completes.
If registration fails, the system will automatically try to register again. 
If it fails after the third try, the handset shows Registration failed, 
then Put handset on  �ASE to register. This may take up to five 
minutes to occur. When the handset displays Put handset on  �ASE 
to register, please start again from Step 1 above.
NOTE: You cannot register a handset if any other system handset is in use.

Make sure you plug the telephone line cord securely and 
firmly into the telephone base and the telephone wall jack.
Charge the battery in the cordless handset for at least 16

handset to the charger when not in use.
If the battery is depleted, charge the handset for at least 30 
minutes before you use it. See page 6 for details.

Troubleshooting
If the previous suggestions do not work, disconnect the 
telephone base from the telephone jack and connect the jack 
to a different phone. If there is no dial tone on that phone 
either, the problem is in your wiring or telephone service. 
Contact your telephone service provider.
Your line cord may be defective. Try installing a new line cord.
I cannot dial out.
Try all the suggestions above.
Make sure you have a dial tone before dialing. The cordless 
handset may 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 may 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 may 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 
may have moved out of range.
Reset the telephone base. Unplug the electrical power. Wait 
for 15 seconds then plug it back in. 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.

The batteries do not hold a charge.
If the cordless handset is in the telephone base or charger 
and the charge light is not on, refer to The charge light is off 
(page 19).
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.
If the battery is depleted, it may take approximately 30 
minutes to charge the handset before it shows Low battery. 
Refer to the table on page 6 for details.
You may need to purchase a new battery. Refer to �attery 
installation and charging in this user’s manual on pages 6-7.

Troubleshooting
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 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 may 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 may have 
better reception in a high area.
If 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.
When using a speakerphone, controlling background noise 
in your environment is essential. While you are listening 
to your party, press M�TE/DELETE to temporarily turn your 
microphone off. When it is your turn to speak, remember to 
press M�TE/DELETE again to turn the microphone on.
Excessive background noise will cause a speakerphone to fade 
in and out. Try controlling the background noise by turning off 
any audio devices near the speakerphone. Also, try to avoid 
interrupting the person at the other end of the conversation 
while they are speaking. If background noise cannot be 
controlled, you should terminate speakerphone operation and 
return to normal handset mode.
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 TL92271/TL92371/TL92471/TL96271/TL96371/
TL96471 user’s manual provided with your 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.
