NATIONAL ELECTRICAL CODE
19. DAMAGE REQUIRING SERVICE
Unplug this unit from the wall outlet and refer
servicing to qualified service personnel under the
following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen
into the unit.
c. If the unit has been exposed to rain or water.
d. If the unit 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 unit to its normal
operation.
e. If the unit has been dropped or the cabinet has
been damaged.
f. When the unit exhibits a distinct change in
performance, this indicates a need for service.
20. REPLACEMENT PARTS
When replacement parts are required, be sure the
service technician uses replacement parts specified
by the manufacturer or those that have the same
characteristics as the original parts.
Unauthorized substitutions may result in fire, electric
shock or other hazards.
21. SAFETY CHECK
Upon completion of any service or repairs to this
unit, ask the service technician to perform safety
checks to determine that the unit is in proper
operating condition.
22. HEAT
The product should be situated away from heat
sources such as radiators, heat registers, stoves, or
other products (including amplifiers) that produce heat.
23. 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.
