Troubleshooting
• 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 starts
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 such as HAM radios and other DECT
phones can cause interference with your cordless telephone.
Try installing your telephone as far away as possible from these
types of electronic devices.
• Completely remove then replace the battery. Place the
cordless handset in the telephone base. Wait for the cordless
handset to reestablish 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.
