• Make sure all plugs are connected properly. Inspect the telephone line
cord connections at the wall jack and telephone. Also inspect the coiled
handset cord connections at both ends.
• Unplug the telephone and connect it to another wall jack. If it still does
not work and other telephones in your home are working, the problem is
with this telephone.
Telephone does not ring.
Make sure the RINGER switch is set to LO or HI.
•
• If there are several other telephones on the same line, try disconnecting
some of the other telephones. Having too many telephones connected can
also create problems such as low ringer volume or impaired sound quality
during calls.
Difficulty storing numbers in memory.
• Make sure you are pressing the correct sequence of keys for storing
numbers.
• If you are interrupted by a recorded announcement asking you to hang up
or by a loud buzzing noise, hang up and store the number without lifting
the handset.
Screen is blank
• Make sure the batteries are correctly installed.
• Replace batteries with new batteries.
Caller ID isn't working.
• Caller ID is a subscription service. You must subscribe to this service from
your telephone service provider for this feature to work on your telephone.
• 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 caused by DSL interference. Please contact your
DSL service provider for more information about DSL filters.
• Your caller must be calling from an area that supports caller ID.
• Both your and your caller's telephone service providers must use
equipment that is compatible with caller ID.
