This precaution may be particularly important in rural areas.The Ringer Equivalence Number (REN) assigned to each terminal device provides anindication of the maximum number of terminals allowed to be connected to a telephoneinterface. The termination on an interface may consist of any combination of devices subjectonly to the requirement that the sum of the Ringer Equivalence Numbers of all the devices doesnot exceed 5.Laser safety statementAll Gateway systems equipped with CD and DVD drives comply with the appropriate safetystandards, including IEC 825. The laser devices in these components are classified as “Class 1Laser Products” under a US Department of Health and Human Services (DHHS) RadiationPerformance Standard. Should the unit ever need servicing, contact an authorized servicelocation.Television antenna connectors protection (forsystems fitted with TV/cable TV tuner cards)External television antenna groundingIf an outside antenna or cable system is to be connected to your Gateway PC, make sure thatthe antenna or cable system is electrically grounded to provide some protection against voltagesurges and static charges.Article 810 of the National Electrical Code, ANSI/NFPSA 70, provides information with regard toproper grounding of the mast and supporting structure, grounding of the lead-in wire to anantenna discharge unit, size of grounding conductors, location of antenna discharge unit,connection to grounding electrodes, and requirements for the grounding electrode.Cable distribution system should be grounded (earthed) in accordance with ANSI/NFPA 70, theNational Electrical Code (NEC), in particular Section 820.93, Grounding of Outer Conductive Shieldof a Coaxial Cable.WarningTo avoid electrical shock or equipment malfunction do not attempt tomake electrical ground connections by yourself.
