HCT 21F9D-P, Owner'S Manual

12. LIGHTNING

To protect your unit from a lightning storm, or when it is left unattended and unused for long 

periods of time, unplug it from the wall outlet and disconnect the antenna or cable system. 
This will prevent damage to the unit due to lightning and power line surges.

13. POWER LINES

An outside antenna system should not be located in the vicinity of overhead power lines or 

other electric light or power circuits, or where it can fall into such power lines or circuits. 
When installing an outside antenna system, extreme care should be taken to keep from 
touching such power lines or circuits, as contact with them might be fatal.

14. OVERLOADING

Do not overload wall outlets and extension cords, as this can result in a risk of fire or electric 

shock.

15. OBJECT AND LIQUID ENTRY

Do not push objects through any openings in this unit, as they may touch dangerous voltage 

points or short out parts that could result in fire or electric shock. Never spill or spray any type 
of liquid into the unit.

16. SERVICING

Do not attempt to service this unit yourself as opening or removing covers may expose you to 

dangerous voltage or other hazards. Refer all servicing to qualified service personnel.

17. 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.

18. 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 
part. Unauthorized substitutions may result in fire, electric shock or other hazards.

19. 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.

20. HEAT

The product should be situated away from heat sources such as radiators, heat registers, 

stoves, or  other products (including amplifiers) that produce heat.

21. CONNECTING

When you connect the product to other equipment, turn off the power and unplug all of the 

equipment from the wall outlet. Failure to do so may cause an electric shock and serious 
personal injury. Read the owner's manual of the other equipment carefully and follow the
instructions when making any connections.

22. SOUND VOLUME

Reduce the volume to the minimum level before you turn on the product. Otherwise, sudden

high volume sound may cause hearing or speaker damage.
