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: 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.
Note 5: FCC ID label on the final system must be labeled with “Contains FCC ID: 2AD56HLK-7688A” or
“Contains transmitter module FCC ID: 2AD56HLK-7688A”.
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.
The OEM integrator is still responsible for the FCC compliance requirement of the end product, which integrates this
module.
