## **Overview** 

The LM072 Bluetooth® v2.0, v2.1 data module provides a secure and reliable Bluetooth® Classic connection. This wireless connection reaches a range of up to 100m in open space, with the option to add an antenna that suits your requirements e.g. a dipole and PCB antenna. The selected antenna could provide a longer range, omnidirectional or unidirectional connection with nearby Bluetooth® Classic devices. 

The module acts as a standalone unit (i.e. no external MCU required) and/ or can interface with embedded microcontrollers via UART. Peripheral devices can be directly controlled by the module to suit the user application. LM offer technical support to the developer and can create new user applications for the module. 

module, simplifying the manufacturing and testing process. Its SMT side and bottom pads allows for easy integrations into your embedded system.

## **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. 

- Consult the dealer or an experienced radio/TV technician for help. 

## NOTE 2 

to operate the equipment. 

## **FCC Radiation Exposure Statement** 

operating instructions for satisfying RF exposure compliance. 

## Note 1 

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 

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. 

## Note 2 

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.

## **FCC Radiation Exposure Statement (Continued)** 

## 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 

VVXLM072”. 

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
