Your telephone company may discon­tinue your service if your equipment
causes harm to the telephone network.
They will notify you in advance of
disconnection, if possible. During
notification, you will be informed of
your right to file a complaint with the
FCC.

Occasionally, your telephone company
may make changes in its facilities,
equipment, operation, or procedures

advance notice of the change to give
you an opportunity to maintain uninter­rupted service.

The base unit contains no user ser­viceable parts. The handset contains
a user replaceable battery pack.

This equipment may not be used on
coin service provided by the phone

number of devices you may connect to
your telephone line and still enable the
devices to ring when you receive a call.
The general rule is that the REN value
should not exceed 5.0A total; ho we ver ,
contact your local telephone company
for the specific number in your area.

If it is determined that your telephone
equipment is malfunctioning, the FCC
