READ THIS FIRST We have designed your telephone to conform to federal regulations and you can connect it to most telephone lines. However, each device you connect to the phone line draws power from it. This power draw is the device's ringer equivalence number, or REN. The REN is shown on the bottom of the phone. 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 (or three in rural areas) your phones might not ring. If ringer operation is impaired, remove one of the devices from the line, or contact your local telephone company for information about boosting the ringer power on the line. If your phone causes problems on the phone line, the telephone company can disconnect your service. The phone company tries to notify your in advance. If advance notice is not practical, the telephone company notifies you as soon as possible and advises you of your right to file a complaint with the FCC. The phone company can also make changes to its lines, equipment, operations, or procedures that could affect the phone's operation. The phone company notifies you in advance, so you can take the necessary steps to prevent interruption of your phone service. FCC STATEMENT Your telephone complies with Part 68 of FCC Rules. You must, upon request, provide the FCC registration number and the REN to your telephone company. These number are shown on the bottom of your phone. NOTE: You must not connect your telephone to: Coin-operated systems Party-line systems Most electronic key phone systems
