IMPORTANT SAFETY INSTRUCTIONS

Read These Instructions

Keep These Instructions

Heed All Warnings

Follow All Instructions

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! 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.

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.

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 electric shock and fire

hazard! Do not locate an outside antenna system in

the vicinity of overhead power lines or power circuits.

Touching power lines or circuits might be fatal.

Protect the Product from Lightning

For added protection, unplug this apparatus during lightning

storms or when unused for long periods of time. 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 goes

out when the apparatus is turned off, regardless of whether it

is still plugged into an AC power source.

Eliminate AC Mains Overloads

WARNING: Avoid electric shock and fire

hazard! Do not overload AC 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.

Connecting the 4250

To connect your 4250 to your entertainment devices, complete these steps.

Identify the additional devices you will

connect to the 4250 and TV. See pages

10 through 12 and the related user’s

guides for more information.

Do not turn on the 4250 or TV yet.

It may take several minutes for the 4250 to receive the latest software, programming, and

service information. Wait until one of the following appearss on the front panel of the 4250

to indicate that the update is complete:

• Current time • Four dashes (- - - -)

Note: If four dashes appear, your 4250 is not authorized. Call your cable service provider.

Connect the coaxial cable that carries the signal from your cable service provider to the

CABLE IN connector on the back panel of the set-top.

Connect your SDTV to the 4250. Refer to the Connection Diagrams section beginning on

page 10.

Plug the 4250 and the TV into an AC power source.

Important: To protect the set-top from power surge damage, ground (earth) your cable

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

To avoid these voltage surges that can be caused by lightning storms and power outages,

plug the set-top into a surge protector to reduce the risk of damage.

Connections for a Standard-Definition TV and VCR

When using the 4250 with an SDTV, you must make one of the following connections to view content. Some

SDTVs may not have all of these connections. In addition, you can make connections to a VCR to archive

recordings to a VCR tape. Refer to your TV and VCR user’s guide and the cabling diagrams in this guide for

more information.

Note: The labeling on your 4250 may vary from the labels shown in the following table.

Required Connections to an SDTV (choose one)

S-Video

The S-Video out connection provides

optimal video to an SDTV. The left and

right audio outputs provide stereo sound.

VCR

The Cable Out connection provides the

video and stereo audio connection to the

VCR. See page 11 for an example.

For VCRs that have Video and Left and Right

audio connectors, you can use the OUT 2

connectors (Video, Left, and Right) on the

4250. These connections generally provide a

higher-quality signal than the standard Cable

Out connection. See page 11 for an example.

Stereo VCR

The Cable Out connection provides both a

video and a stereo audio connection to an

SDTV. See page 10 for an example.

Cable Out

The Video Out connection provides video

to an SDTV. The left and right audio outputs

provide stereo sound. These connections

generally provide a higher-quality signal

than the standard Cable Out connection.
