Troubleshooting
My deskset does not ring when I receive a call.
• Make sure that the ringer is not turned off (page 11).
• Make sure you plug in the power cord securely.
• The deskset may be too far from the main telephone base.
• You may have too many extension telephones on your telephone line to
allow all of them to ring simultaneously. Try unplugging some of the other
telephones.
• The layout of your building might be limiting the operating range. Try
moving the main telephone base to another location, preferably to a
higher location.
• If other telephones in your building are having the same problem, contact
your telephone service provider (charges may apply).
• Test a working telephone at the telephone jack. If another telephone has
the same problem, contact your telephone service provider
(charges may apply).
• Other electronic products such as HAM radios and other DECT phones, can
cause interference with your cordless phone. Try installing your phone as
far away as possible from these types of electronic devices.
• Your line cord might be malfunctioning. Try installing a new line cord.
