When the on/off power light is not illuminated, the apparatus may still be connected to the power source. The light goes 
out when the apparatus is turned off, regardless of whether it is still plugged into an AC power source. 

Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point 
where the cord exits from the apparatus. 

•  Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions. 

•  Do not place this apparatus on a bed, sofa, rug, or similar surface.

•  Do not place this apparatus on an unstable surface.

•  Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifi ers) 

that produce heat.

•  Do not install this apparatus in an enclosure, such as a bookcase or rack, unless the installation provides proper 

ventilation.

•  Do not place entertainment devices (such as VCRs or DVDs), lamps, books, vases with liquids, or other objects on 

top of this product.

Do not use this apparatus near water.

Servicing is required when the apparatus has been damaged in any way, such as a power-supply cord or plug is damaged, 
liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, 
does not operate normally, or has been dropped. 

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

A label on this product indicates the correct power source for this product. Operate this product only from an electrical 
outlet with the voltage and frequency indicated on the product label. If you are uncertain of the type of power supply to 
your home or business, consult your service provider or your local power company.

The AC inlet on the unit must remain accessible and operable at all times.

If this product connects to coaxial cable wiring, be sure the cable system is grounded (earthed). Grounding provides some 
protection against voltage surges and built-up static charges.

If this product connects to an outdoor antenna or cable system, be sure the antenna or cable system is grounded (earthed). 
This provides some protection against voltage surges and built-up static charges.

Article 810 of the National Electric Code (NEC) ANSI/NFPA No. 70-1990, provides the following information:

•  Grounding of the mast and supporting structure

•  Grounding the lead-in wire to an antenna discharge unit

•  Size of the grounding conductors

•  Location of the antenna-discharge unit

•  Connection to grounding electrodes

•  Requirements for the grounding electrodes (see the following antenna grounding diagram as recommended by NEC 

ANSI/NFPA 70)

The servicing instructions in this notice are for use by qualifi ed service personnel only. To reduce the risk of electric shock, do not perform any servicing other than that contained 
in the operating instructions, unless you are qualifi ed to do so.
