Caller ID System 400 (430-0958) Installation Faxback Doc. # 15763 NOTES: To use this system, you must be in an area where Caller ID service is available, and you must subscribe to the service. The Caller ID System displays the caller's name only if this feature is available in your area. The Caller ID System requires four AAA batteries (not included). BEFORE INSTALLATION We have designed the system to conform to federal regulations, and you can connect it to most telephone lines. However, each system (such as telephone, answering machine, or your Caller ID System) that you connect to the telephone line draws power from the line. We refer to this power draw as the device's ringer equivalence number or REN. The REN is shown on the label on the bottom of the system. If you use more that one telephone or other device on the line, add up all the RENs. If the total is more than five, your telephones might not ring. In rural areas, a total REN of three might impair ringer operation. If ringer operation is impaired, disconnect one of the devices from the line. The system complies with Part 68 of FCC Rules. You must, upon request, provide the Federal Communications Commission (FCC) registration number and the REN to your telephone company. Both numbers are shown on the label on the bottom of the system. NOTES: You must not connect the system to any of the following: Coin-operated systems Party-line systems Most electronic key telephone systems (llg/all-06/28/95)
