antenna for optimal performance.Recommended antenna PCB milling empty
or below the antenna protruding plate edges.
2.To ensure the integrity of the ground, the proposed large area paved,
multi-punched.Since Bluetooth to work in the high-frequency band,poor
ground will bring the current sound.All ground network please mains earth as
a reference point.

FCC RF Exposure Requirement
1. At least 20cm separation distance between the antenna and the user’s body must be maintained at all
times. And must not transmit simultaneously with any other antenna or transmitter, except in accordance
with FCC multi transmitter product procedures.
2. To comply with FCC regulations limiting both maximum RF output power and human exposure to RF
radiation, the maximum antenna gain including cable loss in a mobile-only exposure condition must not
exceed 0dBi in the 2.4G band.
3. A user manual with the end product must clearly indicate the operating requirements and conditions that
must be observed to ensure compliance with current FCC RF exposure guidelines.
Please be noticed following information and instructions should be placed in the end-user’s
operating manual
The Module has been granted as single modular approval for mobile applications. This Module must be
installed in the designated host as specified in this manual.
1. Separate approval is required for all other operating configurations, including portable configurations
with respect to 2.1093 and different antenna configurations.
2. The Module and its antenna must not be co-located or operating in conjunction with any other
transmitter or antenna within a host device. This equipment complies with FCC RF radiation exposure
limits set forth for an uncontrolled environment.
3. A label must be affixed to the outside of the end product into which the module is incorporated, with a
statement similar to the following: For SPK-6145-A: This device contains FCC ID: 2AB4GSPK-6145-A.
4. The module shall be in non-detachable construction protection into the finished products, so that the
end-user has to destroy the module while remove or install it.
5. This module is to be installed only in mobile or fixed applications. According to FCC part 2.1091(b)
definition of mobile and fixed devices is:
Mobile device:
A mobile device is defined as a transmitting device designed to be used in other than fixed locations and
to generally be used in such a way that a separation distance of at least 20 centimeters is normally
maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. In
this context, the term ‘‘fixed location’’ means that the device is physically secured at one location and is
not able to be easily moved to another location.
Portable device:
For purposes of this section, a portable device is defined as a transmitting device designed to be used so
that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user.
6. Separate approval is required for all other operating configurations, including portable configurations
with respect to FCC Part 2.1093 and different antenna configurations.
7. A certified modular has the option to use a permanently affixed label, or an electronic label. For a
permanently affixed label, the module must be labelled with an FCC ID: 2AB4GSPK-6145-A. The OEM
TEL：0755-26509941 WEB：www.bolutek.cn Page 9 of 11
BOLUTEK SPK-6145-A Bluetooth Module
manual must provide clear instructions explaining to the OEM the labelling requirements, options and
OEM user manual instructions that are required.
For a host using a this FCC certified modular with a standard fixed label, if (1) the module’s FCC ID is
not visible when installed in the host, or (2) if the host is marketed so that end users do not have
straightforward commonly used methods for access to remove the module so that the FCC ID of the
module is visible; then an additional permanent label referring to the enclosed module: “Contains
Transmitter Module FCC ID: 2AB4GSPK-6145-A” or “Contains FCC ID: 2AB4GSPK-6145-A” must be
used. The host OEM user manual must also contain clear instructions on how end users can find and/or
access the module and the FCC ID.
8. Host product is required to comply with all applicable FCC equipment authorizations regulations,
requirements and equipment functions not associated with the transmitter module portion. Compliance
must be demonstrated to regulations for other transmitter components within the host product; to
requirements for unintentional radiators (Part 15B). To ensure compliance with all non-transmitter
functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and
fully operational. If a host was previously authorized as an unintentional radiator under the Declaration of
Conformity procedure without a transmitter certified module and a module is added, the host
manufacturer is responsible for ensuring that the after the module is installed and operational the host
continues to be compliant with the Part 15B unintentional radiator requirements. Since this may depend
on the details of how the module is integrated with the host, we suggest the host device to recertify part
15B to ensure complete compliance with FCC requirement: Part 2 Subpart J Equipment Authorization
Procedures , KDB784748 D01 v07, and KDB 997198 about importation of radio frequency devices into
the United States.
FCC Certification Requirement:
The end product with an embedded Module may also need to pass the FCC Part 15 unintentional emission
testing requirements and be properly authorized per FCC Part 15.
Note: If this module is intended for use in a portable device, you are responsible for separate approval to
satisfy the SAR requirements of FCC Part 2.1093.
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. Changes or modifications made to
this equipment not expressly approved by Shenzhen Minew Technologies Co.,Ltd. may void the FCC
authorization to operate this equipment.
Warning: Changes or modifications made to this device not expressly approved by Shenzhen Bolutek
Electronical Technology Co.,Ltd may void the FCC authorization to operate this device.
Note: The manufacturer is not responsible for any radio or tv interference caused by unauthorized
modifications to this equipment. Such modifications could void the user’s authority to operate the
equipment.

The OEM integrator is responsible for the compliance to all the rules that apply to the product into which
this certified RF module is integrated.
Bolutek will assist by providing guidance to you if you have difficulties with compliance to Part 15B
requirements.”
Manual Information To the End User:
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.
This device is intended only for OEM integrators under the following conditions:
The antenna must be installed such that 20 cm is maintained between the antenna and users, and The
transmitter module may not be co-located with any other transmitter or antenna. As long as 2 conditions
above are met, further transmitter test will not be required. However, the OEM integrator is still
responsible for testing their end-product for any additional compliance requirements required with this
module installed.
IMPORTANT NOTE:
In the event that these conditions cannot be met (for example certain laptop configurations or co-location
with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID 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.
