IMPORTANT SAFETY INSTRUCTIONS

Read these instructions.

Keep these instructions.

Heed all warnings.

Follow all instructions.

Do not use this apparatus near water.

Clean only with dry cloth.

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

instructions.

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

apparatus (including amplifiers) that produce heat.

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 electric shock and fire hazard! 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.

IMPORTANT SAFETY INSTRUCTIONS

vi 4042831 Rev A

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.

Eliminate AC Power/Mains Overloads

WARNING: Avoid electric shock and fire hazard! Do not overload AC power/mains,

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

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

instructions for those products.

Provide Ventilation and Select a Location

Remove all packaging material before applying power to the product.

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 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 block ventilation openings.

Operating Environment

This product is designed for operation indoors with a temperature range from 32° to 104° F (0° to 40°C).

Each product should have adequate spacing on all sides so that the cooling air vents on the chassis are

not blocked.

Protect from Exposure to Moisture and Foreign Objects

WARNING: Avoid electric shock and fire hazard! Do not expose this product to

dripping or splashing liquids, rain, or moisture. Objects filled with liquids, such as

vases, should not be placed on this apparatus.

WARNING: Avoid electric shock and fire hazard! Unplug this product before cleaning.

Do not use a liquid cleaner or an aerosol cleaner. Do not use a magnetic/static cleaning

device (dust remover) to clean this product.

WARNING: Avoid electric shock and fire hazard! Never push objects through the

openings in this product. Foreign objects can cause electrical shorts that can result in

electric shock or fire.
