d)

If the product does not operate normally by following 
the operating instructions. Adjust only those controls 
that are covered by the operating instructions as an 
improper adjustment of other controls may result in 
damage and will often require extensive work by a 
qualified technician to restore the product to its normal 
operation,

e)

If the product has been dropped or damaged in any 
way, and 

f)

When the product exhibits a distinct change in perfor-
mance - this indicates a need for service.

Replacement Parts – When replacement parts are required, 
be sure the service technician has used replacement parts 
specified by the manufacturer or have the same 
characteristics as the original part. Unauthorized 
substitutions may result in fire, electric shock, or other 
hazards.

Safety Check – Upon completion of any service or repairs to 
this product, ask the service technician to perform safety 
checks to determine that the product is in proper operating 
condition.

sources such as radiators, heat registers, stoves, or other 
products (including amplifiers) that produce heat.

Outdoor Antenna Grounding – If an outside antenna or 
cable system is connected to the product, be sure the antenna 
or cable 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 discharge unit, size of grounding conductors, 
location of antenna discharge unit, connection to grounding 
electrodes, and requirements for the grounding electrode.

Note to CATV system installer:
This reminder is provided to call the CATV system installer’s 
attention to Article 820-40 of the NEC that provides 
guidelines for proper grounding and, in particular, specifies 
that the cable ground shall be connected to the grounding 
system of the building, as close to the point of cable entry as 
practical.
