Troubleshooting
My cordless handset does not ring when I receive a call.
• Make sure that the ringer is not turned off. Refer to Ringer volume on page 14.
• 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 the telephone
base or charger when not in use.
• You may have too many extension telephones on your telephone line to
allow all of them to ring simultaneously. Try unplugging one telephone at a
time until the telephone start ringing.
• 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 telephone service. Contact your telephone
service provider (charges may apply).
• Test a working telephone at the telephone wall jack. If another telephone
has the same problem, the problem is the telephone wall jack. Contact your
telephone service provider (charges may apply).
• Other electronic products can cause interference to your cordless telephone.
Try installing your telephone as far away as possible from electronic devices
such as wireless routers, or other cordless telephones.
• Reinstall the battery, and place the cordless handset in the telephone
base. Wait for the cordless handset to re-establish its connection with the
telephone base. Allow up to one minute for this to take place.
• Your telephone line cord might be malfunctioning. Try installing a new
telephone line cord.
My 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.
• Your caller must be calling from an area that supports caller ID.
• Both your and your caller's telephone service providers must use caller ID
compatible equipment.
