OPERATION
Receiver Volume Contr ol
The Receiver Volume Control can be adjusted for a comfortable 
listening level. The switch has variable volume positions.
Redial
The telephone always stores in memory the last phone number 
dialed. To dial the same number again, lift the handset and 
press  .
Erasing Redial
For privacy, you can erase the redial memory. Lift the handset, 
then press any digit (1-9).
Mute
Hold down  to turn off the handset microphone. You can 
then talk privately to someone else in the room without the 
person on the phone hearing you. You will still be able to hear 
the other person, but anything you say will not be heard. When 
you release the button, your caller will again be able to hear 
your voice.
Ringer Volume Contr ol
The RINGER switch allows you to turn the telephone ringer OFF, 
or set it to ring at LO or HI volume. You can dial or answer calls 
normally when the ringer is off. Other telephones in your home 
will still ring; they are not affected by the switch.
T emporary Tone Dialing

service. This is useful if you need to send tone signals for 
access for telephone banking or long-distance services.

1. With the Dial Mode switch set to 
DP (dial pulse), dial a telephone 
number.
2. Press  ; all buttons pressed 
after this will send tone signals.
3. After you hang up, the phone automatically returns to rotary service.

If you have difficulty operating this phone, try the 
suggestions below.
No Dial Tone
☞ Make sure all plugs are connected properly. Inspect the
line cord connections at the modular jack and at the 
telephone. Also inspect the coiled handset cord 
connections at both ends.
☞ Unplug the telephone and connect it to another modular
jack. If it still does not work, try another telephone; if 
neither telephone works, the problem is not in this 
telephone. The trouble may be caused by local 
telephone company lines, central office equipment, or 
the wiring in your home.
Calls Cannot Be Dialed, Or Are Dialed Slowly
This product comes set in the tone (TT) mode. Make sure 
you choose the correct dialing method (TT/DP); touch tone 
dialing will not work if you have dial pulse service.
Telephone Does Not Ring
☞ Make sure the RINGER Volume switch is not set to OFF. 
☞ If there are several other phones on the same line, try
disconnecting some of the other telephones. Having too 
many telephones can also create problems such as low 
ringer volume or impaired quality during calls.
