NOTE:
Please notice that 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 FCC ID:2AB2RJS-BTM256, IC: 11877A-JSBTM256” any similar wording that expresses
the same meaning may be used.
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 not expressly approved by the party responsible for compliance could void the
user’s authority to operate the equipment.
This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the
following two conditions: (1) this device may not cause interference, and (2) this device must accept any
interference, including interference that may cause undesired operation of the device.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio

1. INTRODUCTION
The JS-BTM256 Bluetooth® module is a perfect solution for smart phones and portable devices. It
can be connected with any Bluetooth® devices in an operating range. It is slim and light so the
designers can have better flexibilities for the product shapes.
The JS-BTM256 Bluetooth® module complies with Bluetooth® specification version 4.0(dual mode). It
supports multiple profiles.It supports maximum bluetooth data rates over HCI UART interface and
provides audio PCM interface for bluetooth.
the user manual must state the following items：
a. The module is limited to OEM installation ONLY;
b. The OEM integrators is responsible for ensuring that end-user has no manual instructions to
remove or install module;
c. The module is limited to installation in mobile or fixed application
d. The separate approval is required for all other operating configurations, including portable
configuration with respect to Part 2.1093 and different antenna configurations;
e. the host manufacturer is responsible for ensuring that after the module is installed and
operational the host continues to be compliant with the Part 15B unintentional radiator
requirements
Installation Method:
a. About the operating environment of wireless Bluetooth, the wireless signals include the
Bluetooth application are affected largely by the environment around, such as trees,metals.etc. The
barriers will absorb the wireless signals partly and the distance of the data-transmission will be
affected partly in the real application.
b. Module serial port level is 1.8V. You need to increase level translator chip if you need to connect
with 3.3V level system.
c. The Bluetooth module need to be matched with the existing system.put in the outer shell. Because
the wireless radio-frequency signal will be shield by metal shell. You’d better not to install in the metal
shell.
d. PCB Design:The metal will weaken radio,you’d better not to set the gound and wire under the
antenna.
