SAVE THESE INSTRUCTIONS FOR LATER USE.
FOLLOW ALL WARNINGS AND INSTRUCTIONS MARKED ON THE AUDIO 
EQUIPMENT.

1  Read instructions 

- All the safety and operating instructions should be read 

before the product is operated.

2  Retain instructions 

- The safety and operating instructions should be retained 

for future reference.

3  Heed Warnings 

- All warnings on the product and in the operating instructions 

should be adhered to.

4  Follow Instructions 

- All operating and use instructions should be followed.

5 Cleaning 

- Unplug this product from the wall outlet before cleaning. Do not use 

liquid cleaners or aerosol cleaners. Clean only with a dry cloth.

6 Attachments 

- Do not use attachments not recommended by the product 

manufacturer as they may cause hazards.

7  Water and Moisture 

- Do not use this product near water-for example, near a 

bath tub, wash bowl, kitchen sink, or laundry tub; in a wet basement; or near a 
swimming pool; and the like.

8 Accessories 

- Do not place this product on an unstable cart, stand, tripod, 

bracket, or table. The product may fall, causing serious injury to a child or adult, 
and serious damage to the product. Use only with a cart, stand, tripod, bracket, or 
table recommended by the manufacturer, or sold with the product. Any mounting 
of the product should follow the manufacturer’s instructions, and should use a 
mounting accessory recommended by the manufacturer.

A product and cart combination should be moved with care. Quick 
stops, excessive force, and uneven surfaces may cause the product and 
cart combination to overturn.

10 Ventilation 

- Slots and openings in the cabinet are provided for ventilation and 

to ensure reliable operation of the product and to protect it from overheating, and 
these openings must not be blocked or covered. The openings should never be 
blocked by placing the product on a bed, sofa, rug, or other similar surface. This 
product should not be placed in a built-in installation such as a bookcase or rack 
unless proper ventilation is provided or the manufacturer’s instructions have been 
adhered to.

11  Power Sources 

- This product should be operated only from the type of power 

source indicated on the marking label. If you are not sure of the type of power 
supply to your home, consult your product dealer or local power company. The 
primary method of isolating the amplifier from the mains supply is to disconnect 
the mains plug. Ensure that the mains plug remains accessible at all times. Unplug 
the AC power cord from the AC outlet if the unit will not be used for several 
months or more.

12  Grounding or Polarization 

- This product may be equipped with a polarized 

alternating current line plug (a plug having one blade wider than the other). This 
plug will fit into the power outlet only one way. This is a safety feature. If you are 
unable to insert the plug fully into the outlet, try reversing the plug. If the plug 
should still fail to fit, contact your electrician to replace your obsolete outlet. Do 
not defeat the safety purpose of the polarized plug.

13  Power Cord Protection 

- Power supply cords should be routed so that they 

are not likely to be walked on or pinched by items placed upon or against them, 
paying particular attention to cords at plugs, convenience receptacles, and the 
point where they exit from the product.

14  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 Section 820-40 of 
the NEC which 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.

15 Lightning 

- For added protection for this product during 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 product due to lightning and power line surges.

16  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.

17 Overloading 

- Do not overload wall outlets, extension cords, or integral 

convenience receptacles as this can result in a risk of fire or electric shock.

18  Object and Liquid Entry 

- Never push objects of any kind into this product 

through openings as they may touch dangerous voltage points or short-out parts 
that could result in a fire or electric shock. Never spill liquid of any kind on the 
product.

WARNING: THE APPARATUS SHOULD NOT BE EXPOSED TO DRIPPING 
OR SPLASHING, AND OBJECTS FILLED WITH LIQUIDS, SUCH AS VASES, 
SHOULD NOT BE PLACED ON THE APPARATUS. AS WITH ANY ELECTRONIC 
PRODUCTS, USE CARE NOT TO SPILL LIQUIDS INTO ANY PART OF THE 
SYSTEM. LIQUIDS CAN CAUSE A FAILURE AND/OR A FIRE HAZARD.
