Radio Shack ET-928 Conference Phone User Manual

Important:
Cordless phones such as this one
require AC power to operate. When
AC power is off, you cannot dial out
or receive incoming calls using your
ET-928. For this reason, the ET-928
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.
• Some cordless phones operate at
frequencies that might cause inter-
ference to nearby TVs and VCRs.
To minimize or prevent such interfer-
ence, the base of the cordless
phone should not be placed near or
on top of a TV or VCR.
READ THIS BEFORE
INSTALLATION
Your telephone conforms to federal reg-
ulations, and you can connect it to most
telephone lines. However, each device
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
total REN of three might impair ringer
operation. If ringer operation is impaired,
remove a device from the line.
FCC STATEMENT
