PRECAUTIONS
The Bluetooth module works in the 2.4G wireless frequency band. The influence of various factors on wireless transmission and reception should be avoided as much as possible. Pay attention to the following points
- Avoid using metal for the product shell surrounding the Bluetooth. When using a partial metal shell, try to keep the antenna part of the module away from the metal part. The metal connecting wires or metal screws inside the product should be kept away from the antenna part of the module as much as possible.
- The antenna part of the module is placed around the on-board PCB, and it is not allowed to be placed in the PCB. The carrier board under the antenna is milled empty, and the direction parallel to the antenna is not allowed to lay copper or trace. Or directly expose the antenna part directly to the carrier board.
- It is recommended to use insulating material to isolate the module mounting position of the substrate, for example, place a whole piece of silk screen in this position.
FCC Statement
PCB Antenna with antenna gain 0.55dBi（The on-board antenna that can be used with the module, the gain is not more than 0.55dBi） 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 the equipment.
Note: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part15 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.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. The devices must be installed and used in strict accordance with the manufacturer’s instructions as described in the user documentation that comes with the product. Any company of the host device which install this modular with modular approval should perform the test of radiated& conducted emission and spurious emission, etc. according to FCC part 15C : 15.247 and 15.209 &15.207 ,15B Class B requirement, Only if the test result comply with FCC part 15C : 15.247 and 15.209 &15.207 ,15B Class B requirement，then the host can be sold legally.
We will retain control over the final installation of the modular such that compliance of the end product is assured. In such cases, an operating condition on the limit modular approval for the module must be only approved for use when installed in devices produced by a specific manufacturer. If any hardware modify or RF control software modify will be made by host manufacturer,C2PC or new certificate should be apply to get approval, if those change and modification made by host manufacturer not expressly approved by the party responsible for compliance,then it is illegal.
FCC Radiation Exposure Statement
This modular complies with FCC RF 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. If the FCC
identification number 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. This
exterior label can use wording such as the following: “Contains Transmitter
Module FCC ID: 2A4MI-JW-496 Or Contains FCC ID: 2A4MI-JW-496”.When the module
is installed inside another device, the user manual of the host must contain
below warning statements;
OEM INTEGRATION INSTRUCTIONS:
The module shall be only used with the internal on‐board antenna that has been
originally tested and certified with this module. However, the OEM integrator
is still responsible for testing their end‐product for any additional
compliance requirements required with this module installed (for example,
digital device emissions, PC peripheral requirements, etc.). The end‐product
may need Verification testing, Declaration of Conformity testing, a Permissive
Class II Change or new Certification. Please involve a FCC certification
specialist in order to determine what will be exactly applicable for the
end‐product. Validity of using the module certification: In the event that
these conditions cannot be met (for example certain laptop configurations or
co‐location with another transmitter), then the FCC authorization for this
module in combination with the host equipment is no longer considered valid
and the FCC ID of the module cannot be used on the final product. In these
circumstances, the OEM integrator will be responsible for re‐evaluating the
end product (including the transmitter) and obtaining a separate FCC
authorization. In such cases, please involve a FCC certification specialist in
order to determine if a Permissive Class II Change or new Certification is
required.
Upgrade Firmware:
The software provided for firmware upgrade will not be capable to affect any
RF parameters as certified for the FCC for this module, in order to prevent
compliance issues.
End product labeling:
This transmitter module is authorized only for use in device.The final end
product must be labeled in a visible area with the following: “Contains 2A4MI-
JW-496”. Information that must be placed in the end user manual: The OEM
integrator has to be aware not to provide information to the end user
regarding how to install or remove this RF module in the user’s manual of the
end product which integrates this module. The end user manual shall include
all required regulatory information/warning as show in this manual. When the
module is installed inside another device, the user manual of the host must
contain below warning statements;
