If the module is installed in a portable host, a separate SAR evaluation is required to confirm compliance with relevant FCC portable RF exposure rules. Antennas The antenna is permanently attached to the module. Antenna type: PCB pattern antenna Label and compliance information The module is labeled with its own FCC/IC. If the FCC ID/IC 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. In that case, the final end product must be labeled in a visible area with the following:

Contains FCC ID: CCECRM-1356BM , Contains IC: 22254-CRM1356BM The host manual shall include the following regulatory statement:

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is maintained between the radiator (antenna) and all persons at all times. Information on test modes and additional testing requirements This module is tested in a standalone. Co-location of this module with other transmitters that operate simultaneously are required to be evaluated using the FCC multi-transmitter procedures. Additional testing, Part 15 Subpart B disclaimer The modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, 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. The host product may need to be evaluated against the FCC Part 15B criteria for unintentional radiators in order to be properly authorized for operation as a Part 15 digital device.

MODULAR APPROVAL LETTER

Modular Approval Requirement

Answers

Yes

Yes

Yes

(i) 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.

(ii) 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.

(iii) The modular transmitter must have its own power supply regulation. Yes

(iv) 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.

(v) 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)).

(vi) The modular transmitter must be equipped with either a

permanently affixed label or must be capable of electronically displaying

its FCC identification number.

(vii) 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.

(viii) 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.
