FCC and ACTA information
If this equipment was approved for connection to the telephone network prior to July 23, 2001, it complies with Part 68 of the Federal Communications Commission (FCC) rules. If the equipment was approved after that date, it complies with the Part 68 rules and with Technical Requirements for Connection of Equipment to the Telephone Network adopted by the Administrative Council for Terminal Attachments (ACTA). We are required to provide you with the following information. 1. Product identifier and REN information The label on the back or bottom of this equipment contains, among other things, an identifier indicating product approval and the Ringer Equivalence Number (REN). This information must be provided to your local telephone company upon request. For equipment approved prior to July 23, 2001, the product identifier is preceded by the phrase FCC Reg No. and the REN is listed separately. For equipment approved after that date, the product identifier is preceded by US and a colon (:), and the REN is encoded in the product identifier without a decimal point as the sixth and seventh characters following the colon. For example, the product identifier US:AAAEQ03T123XYZ indicates the REN would be 0.3. The REN is used to determine how many devices you may connect to your telephone line and still have them ring when you are called. In most, but not all areas, the sum of all RENS should be five (5.0) or less. You may want to contact your local telephone company for more information. 2. Connection and use with the nationwide telephone network The plug and jack used to connect this equipment to the premises wiring and the telephone network must comply with the applicable part 68 rules and technical requirements adopted by ACTA. A compliant telephone cord and modular plug is provided with this product. It is designed to be connected to a compatible modular jack that is also compliant.

The telephone company is required to notify you if such changes are planned. 5. Hearing aid compatibility If this product is equipped with a corded or cordless handset, it is hearing aid compatible. 6. Programming/testing of emergency numbers If this product has memory dialing locations, you may choose to store police, fire department and emergency medical service telephone numbers in these locations. If you do, please keep three things in mind: a. We recommend that you also write the telephone number on the directory card (if applicable), so that you can still dial the emergency number manually if the memory dialing feature does not work. b. This feature is provided only as a convenience, and the manufacturer assumes no responsibility for customer reliance upon the memory feature. c. Testing the emergency telephone numbers you have stored is not recommended. However, if you do make a call to an emergency number: You must remain on the line and briefly explain the reason for the call before hanging up. Programming/testing of emergency numbers should be performed during off-peak hours, such as in the early morning or late evening, when the emergency services tend to be less busy.
