This

device

complies

with

Part

15

of

the

FCC

Rules.

Operation

is

subject

to

the

following

two

conditions:

•

This

device

may

not

cause

harmful

interference,

and

•

This

device

must

accept

any

interference

received

including

interference

that

may

cause

undesired

operation.

This

equipment

has

been

tested

and

found

to

comply

with

the

limits

for

a

Class

B

digital

device,

pursuant

to

Part

15

of

the

FCC

Rules.

These

limits

are

designed

to

provide

reasonable

protection

against

harmful

interference

in

a

residential

installation.

This

equipment

generates,

uses

and

can

radiate

radio

frequency

energy

and,

if

not

installed

and

used

in

accordance

with

manufacturer’

s

instructions,

may

cause

harmful

interference

to

radio

communications.

However,

there

is

no

guarantee

that

interference

will

not

occur

in

a

particular

installation.

If

this

equipment

does

cause

harmful

interference

to

radio

or

television

reception,

which

can

be

determined

by

turning

the

equipment

off

and

on,

the

user

is

encouraged

to

try

to

correct

the

interference

by

one

or

more

of

the

following

measures:

•

Reorient

or

relocate

the

receiving

antenna.

Increase

the

separation

between

the

equipment

and

receiver.

Connect

the

equipment

to

an

outlet

on

a

circuit

different

from

that

to

which

th

e

receiver

is

connected.

Consult

the

dealer

or

an

experienced

radio/TV

technician

for

help.

•

The

use

of

shielded

cables

for

connection

of

the

monitor

to

the

graphics

card

is

required

to

assure

compliance

with

FCC

regulations.

Changes

or

modifications

to

this

unit

not

expressly

approved

by

the

party

responsible

fo

r

compliance

could

void

the

user’s

authority

to

operate

this

equipment.
