 Module Measurement

Reference PCB Package

The Bluetooth operating frequency is 2.4GHz, and the influence of various factors on wireless transceiver should be avoided as much as possible.
Notice:

• Avoid using metal for the part of the product housing that
• The metal screws inside the product should be kept away from the RF part of the module.
• To maximize RF performance, user board layout should follow the following recommendations: 1) Antenna clearance area: the user board located directly under the antenna area of the module cannot have any copper foil (including power, ground, signal layers). 2) Module location: Ideally, the module should be arranged in a corner of the user’s mainboard, and the PCB antenna is located at the far end of the mainboard. This position minimizes the antenna clearance area

Refer to the following settings for the furnace parameters :

FCC Statement
Any Changes or modifications not expressly approved by the party responsible for compliance could void the user’s 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.

OEM Guidance

1. Applicable FCC rules
   This module has been tested and found to comply with part 15.247 requirements for
   Modular Approval.

2. The specific operational use conditions
   This module can be used in loT devices. The input voltage to the module is nominally 3.3V DC. The operational ambient temperature of the module is -40 to 85 degree C. Only the embedded PCB antenna is allowed. Any other external antenna is prohibited.

3. Limited module procedures
   N/A

4. Trace antenna design
   N/A

5. RF exposure considerations
   This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment This equipment should be installed and operated with a minimum distance 20cm between the radiator& your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter the device built into a host as a portable usage, the additional RF exposure evaluation may be required as specified by 2.1093.

6. Antenna
   Antenna type : PCB Antenna; Antenna Max. Peak Gain 0 dBi

7. Label and compliance information
   When the module is installed in the host device, the FCC ID label must be visible through a window on the final device or it must be visible when an access panel, door or cover is easily removed. If not, a second label must be placed on the outside of the final device that contains the following text: “Contains FCC ID: 2A6QWMR-BLE001 The FCC ID can be used only when all FCC ID compliance requirements are met.

8. 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 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 have been corrected.
