Battery and Charging
The whole circuit is running with single cell 3.7v Li-ion battery connecting to the VBAT terminal. VBAT_SENSE is
shorted to this terminal for battery level detection. 5V charging input coming from the micro USB port is connected to the VCHG
terminal. In this typical circuit, a maximum of 150mA charging current can be supported. Note that a decoupling capacitor of
2.2uF should be connected to VCHG.
Host Information
This module was defined to be used for specific host only. The designated host for this module was:
Company: GT-tronics HK Ltd.
Address: B202, Tonic Industrial Center, 19 Lam Hing Street, Kowloon Bay, Hong Kong
Host Model Name: BTSPK
Host brand name: GT-tronics
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 limited 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 BC865RPA: This device contains FCC ID: B4OBC86XRPA.
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: B4OBC86XRPA. The OEM 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: B4OBC86XRPA” or “Contains FCC ID: B4OBC86XRPA” 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
