Important Note: Cordless phones
such as this one require AC power to
operate. When the AC power is off,
you cannot dial out or receive incoming
calls using your ET-557. To be safe,
you should also have a phone that
does not need AC power to operate
(not a cordless phone) so you can still
make and receive calls if there is an
AC power failure.
For your records, we urge you to
record the serial number of your phone
in the space below. The serial number
is located on the bottom panel of the
base.
