The module transmitter will be a limited module

Modular Approval Request FCC (Per 15.212)

FCC ID: 24728-SKIWB663U11

Items to be covered

1. The radio elements of the modular transmitter must have their own

shielding. The physical crystal and tuning capacitors may be located

external to the shielded radio elements.

2. The modular transmitter must have buffered modulation/data inputs (if

such inputs are provided) to ensure that the module will comply with part

15 requirements under conditions of excessive data rates or over-

modulation.

3. The modular transmitter must have its own power supply regulation.

4. The modular transmitter must comply with the antenna and

transmission system requirements of §§15.203, 15.204(b) and

15.204(c). The antenna must either be permanently attached or employ

a “unique” antenna coupler (at all connections between the module and

the antenna, including the cable). The “professional installation”

provision of §15.203 is not applicable to modules but can apply to limited

modular approvals under paragraph (b) of this section.

5. The modular transmitter must be tested in a stand-alone

configuration, i.e., the module must not be inside another device during

testing for compliance with part 15 requirements. Unless the transmitter

module will be battery powered, it must comply with the AC line

conducted requirements found in §15.207. AC or DC power lines and

data input/output lines connected to the module must not contain

ferrites, unless they will be marketed with the module (see §15.27(a)).

The length of these lines shall be the length typical of actual use or, if

that length is unknown, at least 10 centimeters to insure that there is no

coupling between the case of the module and supporting equipment.

Any accessories, peripherals, or support equipment connected to the

module during testing shall be unmodified and commercially available

(see §15.31(i)).

6. The modular transmitter must be equipped with either a permanently

affixed label or must be capable of electronically displaying its FCC

identification number.

(A) If using a permanently affixed label, the modular transmitter

must be labeled with its own FCC identification number, and, if the FCC

identification number is not visible when the module is installed inside

another device, then the outside of the device into which the module is

installed must also display a label referring to the enclosed module. This

exterior label can use wording such as the following: “Contains

Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID:

XYZMODEL1.” Any similar wording that expresses the same meaning

of which must be included in the application for equipment authorization,

or, must provide adequate instructions along with the module which

explain this requirement. In the latter case, a copy of these instructions

must be included in the application for equipment authorization.

(B) If the modular transmitter uses an electronic display of the FCC

identification number, the information must be readily accessible and

visible on the modular transmitter or on the device in which it is installed.

If the module is installed inside another device, then the outside of the

device into which the module is installed must display a label referring to

the enclosed module. This exterior label can use wording such as the

following: “Contains FCC certified transmitter module(s).” Any similar

wording that expresses the same meaning may be used. The user

manual must include instructions on how to access the electronic

display. A copy of these instructions must be included in the application

for equipment authorization.

Yes

7. The modular transmitter must comply with any specific rules or

operating requirements that ordinarily apply to a complete transmitter

and the manufacturer must provide adequate instructions along with the

module to explain any such requirements. A copy of these instructions

must be included in the application for equipment authorization.

8. Radio frequency devices operating under the provisions of this part

are subject to the radio frequency radiation exposure requirements

specified in §§1.1307(b), 1.1310, 2.1091, and 2.1093 of this chapter, as

appropriate. Applications for equipment authorization of modular

transmitters under this section must contain a statement confirming

compliance with these requirements. The modular transmitter must

comply with any applicable RF exposure requirements in its final

configuration. Technical information showing the basis for this statement

must be submitted to the Commission upon request.

Note: If compliance with one or more of the numbered requirements, listed above,

cannot be demonstrated, it may be possible to obtain a “Limited Modular Approval”

(LMA).

Yes
