cordless handset,
and none of the
keys or buttons
work
My cordless
handset does
not ring when
I receive a call
• Make sure the power cord is plugged in securely.
• Make sure that the ringer is turned on. Refer to the
section(s) on ringer selection in this user's manual.
• Make sure the telephone line cord is plugged securely
into the telephone base and the telephone jack. Make
sure the power cord is securely plugged in.
• The cordless handset may be too far from the telephone base.
• Charge the battery in the cordless handset for at least
16 hours. For optimum daily performance, return the
cordless handset to its charger when not in use.
• You may have too many extension telephones on your
telephone line to allow all of them to ring simultane-
ously. Try unplugging some of the other telephones.
• The layout of your home or office might be limiting
the operating range. Try moving the telephone base to
another location, preferably on an upper floor.
• If the other telephones in your home are having the same
problem, the problem is in your wiring or local service.
Contact your local telephone company (charges may apply).
• Test a working telephone at the telephone jack. If anoth-
er telephone has the same problem, the problem is
the phone jack. Contact your local telephone company
(charges may apply).
• Other electronic products can cause interference with
your cordless telephone. Try installing your telephone
as far away as possible from electronic devices wire-
less routers, radios, radio towers, pager towers, cellular
telephones, intercoms, room monitors, televisions, per-
sonal computers, kitchen appliances and other cordless
telephones.
• Your line cord might be malfunctioning. Try installing a
new line cord.
