FCC Information

We have designed your CID to conform to federal regulations, and you can connect it to most telephone lines. However, each CID (and each device, such as a tele- phone or answering machine) that you connect to the telephone line draws power from the line. We refer to this power draw as the device’s ringer equivalence num- ber, or REN. The REN is on the bottom of your CID.

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 (three in rural areas), your phones might not ring. If ring- er operation is impaired, remove a device from the line.

Your CID complies with Part 68 of the FCC Rules. You must, upon request, pro- vide the FCC registration number and the REN to your phone company. Both num- bers are on the bottom of the CID.

You must not connect your CID to:

•coin-operated systems

•party-line systems
