This

device

is

intended

only

for

host

manufacturers

under

the

following

conditions:

•

The

transmitter

module

may

not

be

co-located

with

any

other

transmitter

or

antenna.

•

The

module

shall

be

only

used

with

the

external

antenna(s)

that

has

been

originally

tested

and

certified

with

this

module.

•

The

antenna

must

be

either

permanently

attached

or

employ

a

‘unique’

antenna

coupler.

As

long

as

the

conditions

above

are

met,

further

transmitter

test

will

not

be

required.

However,

the

host

manufacturer

is

still

responsible

for

testing

their

end-product

for

any

additional

compliance

requirements

required

with

this

module

installed

(for

example,

digital

device

emissions,

PC

peripheral

requirements,

etc.).

need

to

provide

Host

manufacturer

must

perform

test

of

emission

and

spurious

emission,

etc.,

according

to

the

modes

for

a

modular

transmitter

in

a

host,

as

well

as

for

multiple

simultaneously

transmitting

modules

or

other

transmitters

in

a

host

product.

Only

when

all

the

test

results

of

test

modes

comply

with

FCC

requirements,

then

the

end

product

can

be

sold

legally.

Additional

testing,

Part

15

Subpart

B

compliant

The

modular

transmitter

is

only

FCC

authorized

for

FCC

Part

15

Subpart

C

15.247

and

that

the

host

product

manufacturer

is

responsible

for

compliance

to

any

other

FCC

rules

that

apply

to

the

host

not

covered

by

the

modular

transmitter

grant

of

certification.

If

the

grantee

markets

their

product

as

being

Part

15

Subpart

B

compliant

(when

it

also

contains

unintentional-radiator

digital

circuity),

then

the

grantee

shall

provide

a

notice

stating

that

the

final

host

product

still

requires

Part

15

Subpart

B

compliance

testing

with

the

modular

transmitter

installed.

This

equipment

has

been

tested

and

found

to

comply

with

the

limits

for

a

Class

B

digital

device,

pursuant

to

Part15

of

the

FCC

Rules.

These
