INSTALLATION
We have designed your phone to con-
form to federal regulations and you can
connect it to most phone lines. However,
each device that you connect to the tele-
phone line draws power from the line.
We refer to this power draw as the
phone’s
ringer equivalence number, or
REN. The REN is on the bottom of your
phone.
If you use more than one phone or other
device on the line, add up all the RENs.
If the total is more than five, your phones
might not ring. In rural areas, a total
REN of three might impair ringer opera-
tion. If ringer operation is impaired, re-
move one of the devices from the line.
FCC STATEMENT
Your telephone complies with Part 68 of
FCC Rules. Upon request, you must
provide the phone’s FCC registration
number and REN to your telephone
company. These numbers are on the
bottom of the base.
Note: You must not connect your tele-
phone to:
• coin-operated systems
• party-line systems
• most electronic key phone systems
