READ THIS BEFORE 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 phones might not ring. In rural areas, a total REN of three might impair ringer operation. If ringer operation is im- paired, 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 phone to any of the following:

•coin-operated systems

•party-line systems

•most electronic key phone sys- tems
