This device complies with the following radio frequency and safety standards. Important to OEM Manufacturer: This following FCC Warning must be included in the HOST User Manual. FCC Warning 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. NOTE 1: 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. NOTE 2: Any 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. FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specific operating instructions for satisfying RF exposure compliance. Note 1: This module certified that complies with RF exposure requirment under portable or mobile or fixed condition, this module is to be installed only in portable or mobile or fixed applications. 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
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. Transmitting devices designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated with a personal computer, are considered to be mobile devices if they meet the 20 centimeter separation requirement. A fixed device is defined as a device is physically secured at one location and is not able to be easily moved to another location. Note 2: Any modifications made to the module will void the Grant of Certification, this module is limited to OEM installation only and must not be sold to end-users, end-user has no manual instructions to remove or install the device, only software or operating procedure shall be placed in the end-user operating manual of final products. Note 3: The device must not transmit simultaneously with any other antenna or transmitter. Note 4: To ensure compliance with all non-transmitter functions the host manufacturer is responsible for ensuring compliance with the module(s) installed and fully operational. For example, 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, LM Technologies Ltd shall provide guidance to the host manufacturer for compliance with the Part 15B requirements. Note 5: FCC ID label on the final system must be labeled with “Contains FCC ID: VVXLM78X” or “Contains transmitter module FCC ID: VVXLM78X”. The transmitter module must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the host product. LM Technologies Ltd is responsible for the compliance of the module in all final hosts.

AT Command Manual v1.3@2010 LM- Technologies Ltd www.lm-technologies.com Page 4 of 181 IntroductionThis document describes the configuration commands to control the operation of following LM Bluetooth devices:1) LM048 adapter2) LM058 adapter3) LM048 SPA adapter4) LM400 module5) LM780 module6) LM071 module7) LM072 module8) LM048v2 adapter9) LM058v2 adapter2 AT command Set2.1 HistoryThe AT command set was developed by Hayes to control the operation of telephony modems. The command set has been extended to control bluetooth device primary operation such as inquiry, connection setup/ disconnection etc. Other AT commands are also available to control the serial port setup and other user friendly features.The Bluetooth device powers up in unconnected state and can be configured using UART interface similar to telephony modems. The device will act as Bluetooth slave by default and can be inquired/connect from other Bluetooth master device in neighborhood. The AT commands can be used to change the default behavior and settings for the current as well as future power up cycles.2.2 TerminologySymbol Description ASCII value (Hex)<cr> Carriage Return 0x0D<lf> Line Feed 0x0A<cr,lf> Carriage return and line feed 0x0D, 0x0AXXXXXXXXXXXX 12 hexadecimal BD address sequence2.3 Command formatAll the AT commands except the “AT” test command use the below command structure:<header><name>< parameters> <cr>
