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.

 17.Servicing - The user should not attempt to service the 

appliance beyond that described in the operating instructions. 
All other servicing 

 

should be referred to qualified service 

personnel.
