Perfect solution for android system (android 4.4 is perfectly compatible, 4.3 only supports one-way operation) The problem of two-way pass-through between IOS system and BK3431Q bluetooth module at the same time. 2. The user interface is designed with a universal serial port and full duplex two-way communication. 3. Support AT instruction. 3.Performance parameter Model Bluetooth specification Power Supply Support V5.0Bluetooth stack Working Current Sleep current Temperature Range Wireless transmission range Transmission power Sensitivity Frequency Range STATICS Panel size F-9398 BluetoothV5.0 2.0-3.6V ATT,GATT,SMP,L2CAP,GAP 10mA(Simple application 20uA~1mA) Under 2uA

(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module. For 15 B (15.107 and if applicable 15.107) compliance, the host manufacturer is required to show compliance with 15 while the module is installed and operating. Furthermore the module should be transmitting and the evaluation should confirm that the module's intentional emissions (15C) are compliant (fundamental / out-of-band). Finally the integrator has to apply the appropriate equipment authorization (e.g. Verification) for the new host device per definition in 15.101. Integrator is reminded to assure that these installation instructions will not be made available to the end user of the final host device. The final host device, into which this RF Module is integrated has to be labelled with an auxilliary lable stating the FCC ID of the RF Module, such as "Contains FCC ID: 2AR7VF-9398

"This device complies with part 15 of the FCC rules. Operation is subject to the following two conditions:

this devicemay not cause harmful interference, and this devicemust accept any interference received, including interference thatmay cause undesired operation."

NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 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 to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. SHENZHENSHI XINZHONGXIN TECHNOLOGY CO., LTD. F-9398 Module statement The single-modular transmitter is a self-contained, physically delineated, component for which compliance can be demonstrated independent of the host operating conditions, and which complies with all eight requirements of 15.212(a)(1) as summarized below. 1) The radio elements have the radio frequency circuitry shielded. 2) The module has buffered modulation/data inputs to ensure that the device will comply with Part 15 requirements with any type of input signal. 3) The module contains power supply regulation on the module. 4) The module contains a permanently attached antenna. 5) The module demonstrates compliance in a stand-alone configuration. 6) The module is labeled with its permanently affixed FCC ID label 7) The module complies with all specific rules applicable to the transmitter, including all the conditions provided in the integration instructions by the grantee. 8) The module complies with RF exposure requirements. This transmitter/module must not be collocated or operating in conjunction with any other antenna or transmitter. 7 of 7 ADDRESS:Block 3, Dong Huan Industrial Park, Sha Jing Town, Baoan District, Shenzhen City, Guangdong, Province, China EBWWW.C-CHIP.COM.CN TEL0755-29179480/81/82 FAX: 0755-84736169
