Requirement of FCC KDB 996369 D03 for module certification:
1.1 List of applicable FCC rules : The module complies with FCC Part 15.247.
1.2 Summarize the specific operational use conditions: The module has been certified for Fix/Mobile applications. The host product operating conditions must be such that there is a minimum separation distance of 20 cm (or possibly greater than 20 cm) between the antenna radiating structures and nearby persons. The host manufacturer is obligated to confirm the use conditions of the host product to ensure that distance specified in the instructions is met. In this case the host product is classified as either a mobile device or a fixed device for RF exposure purposes. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter.
1.3 Limited module procedures: Not applicable.
1.4 Trace antenna designs: Not applicable.
1.5 RF exposure considerations: This equipment complies with FCC’s and IC’s RF radiation exposure limits set forth for an uncontrolled environment. The antenna(s) used for this transmitter must be installed and operated to provide a separation distance of at least 20 cm from all persons and must not be collocated or operating in conjunction with any other antenna or transmitter. Installers must ensure that 20cm separation distance will be maintained between the device and users.
Note: the OEM product manuals must include a statement in order to alert the users of FCC RF exposure compliance.

1.8 Information on test modes and additional testing requirements: When testing host product, the host manufacture should follow FCC KDB Publication 996369 D04 Module Integration Guide for testing the host products. The host manufacturer may operate their product during the measurements. In setting up the configurations, if the pairing and call box options for testing does not work, then the host product manufacturer should coordinate with the module manufacturer for access to test mode software. For wireless Bluetooth, the product under test is set into a link/association with a partnering Bluetooth device, as per the normal intended use of the product. To ease testing, the product under test is set to transmit at a high duty cycle, such as by sending a file or streaming some media content. Alternatively, a BT test set may be used. Simultaneously transmitting modules installed in the host should be all active.
1.9 Additional testing, Part 15 Subpart B disclaimer: The modular transmitter is only FCC authorized for the specific rule parts (FCC Part 15.247) list 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 final host product still requires Part 15 Subpart B compliance testing with the modular transmitter installed when contains digital circuity
The host 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.

4.3 Model Description
4.4 PCB layout Notes
Bluetooth works at the frequency of 2.4GHz, so the influence of various factors on wireless sending and receiving should be avoided. Attention should be paid to the following points:
1. The part of the product enclosure avoids metal, and if the enclosure is metal, an external antenna should be considered.
2. The internal metal screws of the product should be kept away from the RF part of the module.
3. The module should be placed around the motherboard, with the antenna part on the side or corner. Copper or wiring is not allowed in the motherboard area below the module antenna.
