CAUTION

43-103 9.fm Page 3 Tuesday, August 17, 1999 10:12 AM

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-539. For this reason, the E T­539 cordless phone should not be your
only telephone. 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.

This telephone has been tested and
found to comply with all applicable UL
and FCC standards.

Your ET-539 operates on standard ra­dio frequencies, as allocated by the
FCC. Therefore, it is possible for other
radio units operating on similar fre­quencies, within a certain area, to in­advertently intercept your conversa­tions and/or cause interference on
your cordless telephone. This lack of
privacy can occur with any cordless
telephone.

Warning: To prevent f ire or shock
hazard, do not expose t his product
to rain or moisture.

RISK OF ELECTRIC SHOCK.

DO NOT OPEN.

CAUTION: TO REDUCE THE RISK OF
ELECTRIC SHOCK, DO NOT REMOVE
COVER OR BA CK. NO USER-S ERVICE­ABLE PARTS INSIDE. REFER SERVIC­ING TO QUALIFIED PERSONNEL.

This symbol is intended to aler t you
to the p r es en c e o f un in su lated d an ­gerous voltage within the product’s

READ THIS BEFORE
INSTALLATION

We have designed your te lephone to
conform to federal regulations, and
you can connect it to mos t telephone
lines. However, 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 shown on the bottom of your
phone’s base.

If you are using more than one phone
or other device on t he line, add up all
the RENs. If the total is more than five,
your phone might not ring. In rural ar­eas, a total REN of three might im pair
ringer operation. If ringer operation is
impaired, remove a device from the
line.

FCC STATEM ENT

This telephone complies with Part 68

FCC Rules

of

number and the REN to your phone
