Version1.4 Regulatory Module Integration Instructions 2.2 List of applicable FCC rules This device complies with part 15.247 of the FCC Rules. 2.3 Summarize the specific operational use conditions This module can be used in household electrical appliances as well as lighting equipments. The input voltage to the module should be nominally 1.8 to 3.6VDC ,typical value 3.3VDC and the ambient temperature of the module should not exceed 85. The antenna is not field replaceable. If the antenna needs to be changed, the certification should be re-applied. 2.4 Limited module procedures Not applicable 2.5 Trace antenna designs Not applicable 2.6 RF exposure considerations This equipment complies with FCC/ISEDC radiation exposure limits set forth for an uncontrolled environment. If the device built into a host as a portable usage, the additional RF exposure evaluation may be required as specified by 2.1093. Version1.4 2.7 Antennas The module have a permanently attached antenna. 2.8 Label and compliance information The outside of final products that contains this module device must display a label referring to the enclosed module. This exterior label can use wording such as: Contains Transmitter Module FCC ID:

2AABZ-B300D2

,or Contains FCC ID:

2AABZ-B300D2

, Any similar wording that expresses the same meaning may be used. 2.9 Information on test modes and additional testing requirements a) The modular transmitter has been fully tested by the module grantee on the required number of channels, modulation types, and modes, it should not be necessary for the host installer to re-test all the available transmitter modes or settings. It is recommended that the host product manufacturer, installing the modular transmitter, perform some investigative measurements to confirm that the resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g., where a different antenna may be causing additional emissions). b) The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters, digital circuitry, or due to physical properties of the host product (enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand-alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not Version1.4 have any responsibility for final product compliance. c) If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference has been corrected 2.10 Additional testing, Part 15 subpart B disclaimer The final module combi nation 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. The integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC rules, including the transmitter operation and should refer to guidance in KDB 996369. FCC Statement Any Changes or modifications not expressly approved by the party responsible for compliance could void the users authority to operate the equipment. 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. Version1.4
