Important: 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-521. For this reason, the ET-521
cordless phone should not be your only
telephone. To be safe, you should also
have a phone that does not require AC
power to operate (not a cordless phone)
so you can still make and receive calls if
there is an AC power failure.
Your telephone operates on standard ra-
dio frequencies as allocated by the FCC.
Even though the access protection code
prevents unauthorized use of your phone
line, it is possible for other radio units op-
erating on similar frequencies within a
certain area to unintentionally intercept
your conversations and/or cause inter-
ference. This lack of privacy can occur
with any cordless phone.

INSTALLATION
Each device that you connect to the
phone line draws power from the phone
line. We refer to this power draw as the
device’s
ringer equivalence number
, or
REN. The REN is on the bottom of the
base.
If you are using more than one phone or
other device on the line, add up all the
RENs. If the total is more than five, your
phone might not ring. In rural areas, a to-
tal REN of three might impair ringer oper-
ation. If ringer operation is impaired,
remove a device from the line.
FCC STATEMENT
This telephone complies with Part 68 of
FCC Rules
. You must, upon request,
provide the FCC registration number and
the REN to your phone company. These
numbers are on the bottom of the base.
Note: You must not connect your ET-
521 to any of the following:
• coin-operated systems
• party-line systems
• most electronic key phone systems
