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 exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. l'appareil hôte doit porter une étiquette donnant le numéro de certification du module d'Industrie Canada, précédé des mots « Contient un module d'émission », du mot « Contient » ou d'une formulation similaire exprimant le même sens, comme suit
Fihonest Communication Co.,Ltd. Fihonest Communication Co.,Ltd 4 Proprietary and Confidential ® 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. Contact us: We supply with the whole Bluetooth data-transmission solution, various kinds of Bluetooth data-transmission, industrial application areas, PC Bluetooth drive software development technology support.
