Layout and Soldering Considerations To make sure wireless performance is at its best condition, please layout the module on the carrier board as below instructions. 4.1 Carrier board under the antenna area of the module like the picture;

4.2 Keep out enough area for the antenna area;

4.3 Reflow profiles are to be selected according to standard manufacturing process;

4.4 The soldering temperature should be less than 206;

4.5 The module should be placed far away other low frequency and digital circuits;

4.6 The MS50 series modules contain highly sensitive electronic circuitry and are Electrostatic Sensitive Devices (ESD). Handling the MS88 series modules without proper ESD protection may destroy or damage them permanently. Recommended Layout for the Carrier Board

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. This device and its antenna(s) must not be co-located or operating in conjunction with any other antenna or transmitter. 15.105 Information to the user.

(b) For a Class B digital device or peripheral, the instructions furnished the user shall include the following or similar statement, placed in a prominent location in the text of the manual:

Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:

Reorient or relocate the receiving antenna. Increase the separation between the equipment and receiver. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. Consult the dealer or an experienced radio/TV technician for help. The device has been evaluated to meet general RF exposure requirement. The device can be used in portable exposure condition without restriction. Radiation Exposure Statement:

This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. The module should not be installed and operated simultaneously with other radios except additional RF exposure was evaluated for simultaneously transmission. The availability of some specific channels and/or operational frequency bands are country dependent and are firmware programmed at the factory to match the intended destination. The firmware setting is not accessible by the end user. The final end product must be labelled in a visible area with the following:

(2018/11/26) Product name: BLE module FCC ID : 2ABU6-MS88SF2 , is seeking FCC Authorization as a The EUT meets the requirements for as detailed in KDB 996369. Compliance to each of the requirements is described below:

Item Single Modular transmitter /

Single Modular approval /

Modular requirement Yes No Single Limited Modular Approval (Please check one) Single Limited Modular Approval (please check one) Please provide a detailed explanation if the answer is No. Have its own RF shielding Have buffered modulation/data inputs (if such inputs are provided) The modular transmitter must have its own power supply regulation. Meet the antenna requirements of section 15.203 Be tested in a stand-alone configuration, i.e., the antenna, AC or DC power and data input/output lines must be connected to the module but, the module must not be inside another case during testing. Be labeled with its own FCC ID number, and if the FCC ID 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. The modular transmitter is manufactured so that the user can not influence the operation of the transmitter that will operate outside of the scope of the regulations. Address compliance with the Commission`s RF exposure limits in Sections 1.1310 and 2.1093. Yes Yes Yes Yes Yes Yes Yes Yes 1 2 3 4 5 6 7 8 Note:

(1) LMA may be granted when one or more of the requirements in the table above cannot be demonstrated. LMA will also be issued in those instances where applicants can demonstrate that they will retain control over the final installation of the device, such that compliance of the end product is assured. In such cases, an operating condition on the LMA for the module must state that the module is only approved for use when installed in devices produced by a specific manufacturer. When LMA is sought, the application for equipment certification must specifically state how control of the end product into which the module will be installed, and will be maintained, such that full compliance of the end product is always ensured.

(2) Please provide Clear and specific instructions describing the conditions, limitations and procedures for third-parties to use and/or integrate the module into a host device.

(3) For non-Software Defined Radio transmitter modules where software is used to ensure compliance of the device, technical description of how such control is implemented to ensure prevention of third party modification must be provided (see KDB 594280). Note 1: Compliance of a module in its final configuration is the responsibility of the applicant. A host device will not be considered certified if the instructions regarding antenna configuration provided in the original description, of one or more separately certified modules it contains, were not followed. Example: A separately certified low-power transceiver module using Bluetooth technology which is housed in a desktop computer, laptop or peripheral does not require the overall system to be recertified, if the desktop computer, laptop or peripheral, as a stand-alone unit, complies with all applicable technical standards.
