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: 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 requirement under mobile or fixed condition, this 

module is to be installed only in mobile or fixed applications. 

 

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:

 Additional testing and certification may be necessary when multiple modules are used. 

 

Note 4: 

The module may be operated only with the antenna with which it is authorized. Any antenna that is of the 

same type and of equal or less directional gain as an antenna that is authorized with the intentional radiator may be 

marketed with, and used with, that intentional radiator. 

 

Note 5:

 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, ShenZhen HaiLingKe Electronic co., Ltd. 

shall provide guidance to the host manufacturer for compliance with the Part 15B requirements.
