Uniden XCA4500 - Manual (Page 7)

Important Electrical Considerations
Unplug all electrical appliances when you know an electrical storm is
approaching. Lightning can pass through your household wiring and damage
any device connected to it. This unit is no exception.
Warning: Please do not attempt to unplug any appliance during an
electrical storm.
Caution: Changes or modifications to this product not expressly approved
by Uniden, or operation of this product in any way other than
as detailed by this Operating Guide, could void your authority
to operate this product.
Range
This unit is designed to achieve the maximum possible range by transmitting
and receiving according to the highest specifications set forth by the I.C. We
have rated this phone to operate at a maximum distance with the
qualification that the range depends upon the environment in which the
telephone is used. Many factors limit range, and it would be impossible to
include all the variables in our rating. The Maximum Range rating of your
integrated telephone answering device is meant to be used as a means of
comparison against other range claims.
Telephone Line Problems
The FCC has granted the telephone company the right to disconnect service
in the event that your phone causes problems on the telephone line. Also,
the telephone company may make changes in facilities and services which
may affect the operation of your unit. However, your telephone company
must give adequate notice in writing prior to such actions to allow you time
for making necessary arrangements to continue uninterrupted service.
If you are having trouble with your telephone service, you must first
disconnect your phone to determine if it is the cause of your problem. If you
determine that it is the cause, you must leave it disconnected until the
trouble has been corrected.
