Walker W300 Guide De L'utilisateur page 21

➤ Compatibility
• Walker W300's Are
Compatible With Digital
PBX Systems
If a standard, single line phone works,
your Walker phone should also work.
• Walker W300's Are Not
Compatible With Key Systems
Or AT&T PBX Systems
These units have a large electronic box
controlling many phones as one unit.
These types of units may be found in
office buildings and some retirement
homes, nursing homes and condos.
➤ Ringer Volume Problem
• Unable To Hear Phone Ringer
Make sure the ringer volume is not set
to OFF.
Slide the volume adjustment switch to
the large dot and the pitch adjustment
switch to the small dot. This will cause
the ringer to sound at its loudest and
lowest frequency. Typically, low frequen-
cies are easier for people with hearing
loss to detect.
TROUBLE-SHOOTING GUIDE
Consider purchasing a variable pitch
auxiliary ringer such as the Walker
WR100. These devices are exceptionally
loud and can be plugged into any phone
outlet in your home.
➤ Interference Problems
• User Hears Radio Or CB
Transmissions Over The Phone
Contact your local phone company to have
your telephone line checked. A Radio
Frequency Interference (RFI) filter may be
put on the line to minimize this problem.
If you have any telephone service prob-
lems, first make sure you have followed all
of the installation procedures outlined in
this user's guide. Then try to determine if
the source of the problem is the Walker
W300 itself or your phone service. To do
this, disconnect the Walker W-300 and
plug in your standard telephone. If the
trouble persists with the standard tele-
phone, inform your telephone company.
If the trouble is related to only the Walker
W300, review the installation procedures
and the troubleshooting guide before
referring to the Limited Warranty stated
later in this user guide.
