Panasonic KX-TG2551ALS, KX-TG2551NZS Operating Instructions Manual page 56

If you are satisfied with the operation of your telephone service after
plugging in your Permitted Attachment, your installation is completed.
You will be unable to connect this Permitted Attachment if your telephone
service consists only of a wall phone or an old style telephone which is
not connected by means of a modern plug and socket. In such cases a
new socket will need to be installed.
Should the Permitted Attachment not operate when plugged into a
socket, it is either faulty or unsuitable for operation with your telephone
service. It should be returned to the store where purchased or an
Authorised Service Centre.
Service difficulties
If at any time a fault occurs on your telephone service carry out the
following checks before you call for service:
• Disconnect the Permitted Attachment and try using the service with the normal
telephone.
• If the telephone service then operates satisfactorily, the fault is in your
Permitted Attachment. Leave the Permitted Attachment disconnected and
report the fault to its supplier or agent to arrange for repair.
• If when using the telephone the service is still faulty, report the fault to "Service
Difficulties and Faults" for attention.
You are required to keep this Permitted Attachment in good working
order while it is connected to your telephone service. Its construction or
internal circuit must not be modified in any way without permission.
WARNING
This cordless telephone system does not incorporate provision for
secrecy of conversations. Appropriately tuned radio equipment and other
cordless telephone systems in close proximity may be used by a third
party to monitor and possibly interrupt conversations in progress when
this system is on radio operation.
