You may not attempt to open the recorder, as this will void the warranty (with the exception of opening the Smart Card access door on the recorder front panel). There is risk of electrical shock, which may result in damage to the equipment, or personal injury or death. There are no user-serviceable parts inside the recorder. Unauthorized modification will void the warranty. This equipment is hearing-aid compatible. It is recommended that the customer install an AC surge arrestor in the AC outlet to which this device is connected. This is to avoid damage to the equipment caused by local lightning strikes and other electrical surges. RADIO INTERFERENCE The recorder complies with the limits for a Class B digital device, as specified in Part 15 of the FCC Rules. This compliance helps ensure against radio interference with other equipment in a typical residential location. Except for the telephone cable, you are required to use shielded cables and cords, such as coaxial and communication cables, to maintain FCC compliance. The recorder does use radio frequencies during operation. If you do not install or use the recorder properly, radio energy may be generated that can interfere with radio communications. Also, it is possible that radio interference can occur even in a proper installation. The typical symptom of radio interference is distortion of television or radio reception. You can determine if the recorder is the cause by confirming that the interference stops if you unplug the recorder from the power outlet, and the interference returns when you plug the recorder back into the outlet. If none of the remedies on the previous page stops the radio interference, contact a licensed radio/television technician, your satellite dealer, or call the Service Center at 1-800-3333474, for assistance. Page A-2 Appendix National Electrical Code (NEC) A In addition, the FCC provides a booklet that can help you. You can order the booklet from the following address: How to Identify and Resolve Radio-TV Interference Problems Stock No. 004-000-00345-4 U.S. Government Printing Office Washington, DC 20402 NATIONAL ELECTRICAL CODE (NEC) The following text contains excerpts of the National Electrical Code (NEC) that relate to grounding your system. This text contains only portions of the Code, as of the publication date of this Guide. For authoritative guidance, you should consult the latest revision of the National Electrical Code, or a licensed electrician. Also, before doing any installations in your area, it is important that you check for any local codes that may affect the installation of the system. Proper grounding is essential. Improperly grounded or ungrounded systems could result in electrical shock, fire, and death. 250-1. SCOPE This article covers general requirements for grounding and bonding of electrical installations and specific requirements in (a) through (f) below. (a) Systems, circuits and equipment required, permitted or not permitted to be grounded. (b) Circuit conductors to be grounded on grounded systems. (c) Location of grounding connections. (d) Types and sizes of grounding and bonding conductors and electrodes. (e) Methods of grounding and bonding. (f) Conditions under which guards, isolation, or insulation may besubstituted for grounding. 250-81. GROUNDING ELECTRODE SYSTEM. If available on the premises at each building or structure served, each item (a) through (d) below, and any made electrodes in accordance with Sections 250-83 (c) and (d), shall be bonded together to form the grounding electrode system. Interior metal water piping located more than 5 feet (152cm) from the point of entrance to the building shall not be used as a conductor to interconnect the electrodes and the grounding electrode conductor. The bonding jumper shall be installed in accordance with Sections 250-92(a) and (b), shall be sized in accordance with Section 250-94, and shall be connected in the manner specified in Section 250-115. The unspliced grounding electrode conductor shall be permitted to run to any convenient grounding electrode available in the grounding electrode system. Page A-3 User and Installation Guide It shall be sized for the largest grounding electrode conductor required among all the available electrodes. (a) Metal Underground Water Pipe. A metal underground water pipe in direct contact with the earth for 10 feet (3.05m) or more (including any metal well casing effectively bonded to the pipe) and electrically continuous by bonding around insulating joints or sections or insulating pipe to the points of connection of the grounding electrode conductor and the bonding conductors. Continuity of the grounding path or the bonding connection to interior piping shall not rely on water meters. A metal underground water pipe shall be supplemented by an additional electrode of a type specified in Section 25081 or in Section 250-83. The supplemental electrode shall be permitted to be bonded to the grounding electrode ...
