Note :

Measurement made using a PO WER_TABLE entery of TX_PRE 80, INT PA63, EXT PA255. This ensures that the

Bluetooth requirements for ACP and those defined by the FCC and ETSI are satisfied over the operating

temp erature rang of -5Ð to + 45Ð . Although the design is capable of generating in excess of + 18dBm,

regulatory compliance over the full temperature range of -5Ð to + 45Ð will not be satisfied if the transmit power

approaches this value.

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: 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 mobile or fixed
condition, this module is to be installed only in portable or mobile or fixed appl ica tions.

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:
VVXLM400-1” or “Contains transmitter module FCC ID: VVXLM400-1”.

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.
