subject

 

to

 

the

 

following

 

two

 

conditions:

 

1.

 

This

 

device

 

may

 

not

 

cause

 

harmful

 

interference.

 

2.

 

This

 

device

 

must

 

accept

 

any

 

interference

 

received,

 

including

 

interference

 

that

 

may

 

cause

 

undesired

 

operation.

 

This

 

equipment

 

has

 

been

 

tested

 

and

 

found

 

to

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

 

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

 

into

 

an

 

outlet

 

on

 

a

 

circuit

 

different

 

from

 

that

 

to

 

which

 

the
