INSTALLING YOUR T ELEPHONE
MODULAR JACKS
To install your telephone, you must have a modular wall jack
at the desired location, or a 4-prong jack that can be modified with
a 4-prong adapter. If your telephone line does not have a modular
wall jack, or a jack that can be modified, you must have one
installed.
DANGER: To reduce the risk of electrical shock
and personal injury, observe the following when
installing station wiring:
1. Never install telephone wiring during a
lightning storm.
2. Never install telephone jacks in wet locations
unless the jack is specifically designed for
wet locations.
3. Never touch uninsulated telephone wires or
terminals unless the telephone line has been
disconnected at the network interface.
4. Use caution when installing or modifying
telephone lines.
Various types of modular
wall jacks are shown to the
right. The USOC RJ11C
modular wall jack is for desk
telephones and the USOC
RJ11W modular wall jack is
for modular wall telephones.
The USOC RJ11W modular
wall jack must be in the
correct mounting position
before mounting a modular
wall telephone. Check to
make sure it is in the position
shown.
Various types of 4-prong
wall jacks are shown to the
right along with a 4-prong
adapter. The 4-prong
adapter plugs into the wall
jack for modular wall jack
service.

TELEPHONE SERVICE PROBLEMS
If you have any problems with your telephone service,
determine if the problem is with your telephone or the telephone
company lines. BEFORE CALLING THE TELEPHONE COMPANY,
be aware that they may charge you for a service call if the
problem is caused by your telephone.

• Unplug your telephone from the wall jack. Plug a
substitute telephone that is known to work properly into
the same wall jack.
• If the problem persists when using the substitute
telephone, notify the telephone company.
• If the substitute telephone works properly, you must
have your telephone repaired before reconnecting it to
the wall jack.
DIAL TONE BUT NO RINGING
• Check that the RINGER VOLUME CONTROL is not set
to OFF.
• Set the RINGER VOLUME CONTROL to HIGH and
have someone on another line call you. Before
answering the call, set the RINGER VOLUME
CONTROL to the desired volume.
