5)

Do not use this apparatus near water.

6) Clean only with dry cloth.

7) Do not block any ventilation openings. Install in accordance with the manufacturer's

instructions.

8)

Do not install near any heat sources such as radiators, heat registers, stoves, or other

apparatus (including amplifiers) that produce heat.

9) Do not defeat the safety purpose of the polarized or grounding-type plug. A

polarized plug has two blades with one wider than the other. A grounding-type

plug has two blades and a third grounding prong. The wide blade or the third

prong is provided for your safety. If the provided plug does not fit into your outlet,

consult an electrician for replacement of the obsolete outlet.

10)

Protect the power cord from being walked on or pinched particularly at plugs,

convenience receptacles, and the point where they exit from the apparatus.

11) Only use attachments/accessories specified by the manufacturer.

12)

Use only with the cart, stand, tripod, bracket, or table specified by the

manufacturer, or sold with the apparatus. When a cart is used, use caution

when moving the cart/apparatus combination to avoid injury from

tip-over.

13)

Unplug this apparatus during lightning storms or when unused for long periods of

time.

14)

Refer all servicing to qualified service personnel. 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.

Power Source Warning

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.

Ground the Product

WARNING: Avoid electr ic shock a nd fir e haz a rd! I f this pr oduct connects to coa x ia l

cable wiring, be sure the cable system is grounded (earthed). Grounding provides

some protection against voltage surges and built-up static charges.

IMPORTANT SAFETY INSTRUCTIONS

vi TP-00102

Outdoor Grounding System

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)

WARNING: Avoid electr ic shock a nd fir e haz a rd! Do not loca te a n outside a nte nna

system in the vicinity of ove

rhead power lines or power circuits. Touching power lines

or circuits might be fatal.

Protect the Product from Lightning

In addition to disconnecting the AC power from the wall outlet, disconnect the signal inputs.

Verify the Power Source from the On/Off Power Light

When the on/off power light is not illuminated, the apparatus may still be connected to the power

source. The light may go out when the apparatus is turned off, regardless of whether it is still plugged

into an AC power source.

IMPORTANT SAFETY INSTRUCTIONS

TP-00102 vii

Eliminate AC Power/Mains Overloads

WARNING: Avoid e lectr ic shock a nd fire haz a rd! Do not ove rloa d AC powe r/ma ins,

outlets, extension cords, or integral convenience receptacles. For products that require

battery power or other power sources to operate them, refer to the operating

instr uctions for those p roducts.

Handling Disposable Batteries
