    							1. Safety Precautions
    13.Outdoor Antenna Grounding - If an outside antenna is 
    connected to the receiver be sure the antenna system is 
    grounded so as to provide some protection against voltage 
    surges and built-up static charges. Article 810 of the National 
    Electrical Code, ANSI/NFPA 70, provides information with 
    regard to proper grounding of the mast and supporting
    structure, grounding of the lead-in wire to an antenna-dis
    charge unit, size of grounding conductors,location of antenna-
    discharge unit, connection to grounding electrodes and 
    requirements for the grounding electrode.  See Figure 1.
    14.Non-use Periods - The power cord of the appliance should be 
    unplugged from the outlet when left unused for a long period 
    of time.15.Object and Liquid Entry - Care should be taken so that objects 
    do not fall and liquids are not spilled into the enclosure through 
    openings. 
    16.Damage Requiring Service - The appliance should be 
    serviced by qualified service personnel when:
      a) The power-supply cord or the plug has been damaged; or
      b) Objects have fallen, or liquid has been spilled into the
          appliance; or
      c) The appliance has been exposed to rain; or
      d) The appliance does not appear to operate normally or 
          exhibits a marked change in performance; or
      e) The appliance has been dropped, or the enclosure 
          damaged.
