4. Test board description
The test board is mainly used to demonstrate the functions of the HLK-B30 module's lanterns,
sockets and lights. Use the test board to demonstrate remote switch LEDs, color changes, brightness
changes, relay switch lights, etc.
Figure 3 HLK-B30 Module test board
4.1. Switching light function description
Before testing the switch light function, you need to use the serial port to burn the firmware of the
switch light function. The function of the switch lamp mainly realizes the on and off function of the
LED_Y lamp. The function of turning on or off the LED_Y lamp can be controlled by the switch button.
4.2. Enter the distribution network mode
Power off the on the module six times continuously at a time interval of one second, and then waited 6
seconds, the NET led light will flash once every second, indicating that the module has erased the network
configuration information and entered the distribution network. After the network configuration is
successful, the NET led light will be on constantly, indicating that the router is successfully connected.

4.4. Using the Tmall Elf distribution network
Before using the Tmall Elf to configure the network, you need to let the module enter the distribution
mode, then say "Tmall Elf, find device" to the Tmall Wizard, and then follow the prompts of the Tmall
Wizard to configure the device to the same router.
When the device is successfully connected, you can say "Tmall Elf, Turn On the Light" or "Tmall Elf,
Turn Off the Light" to the Tmall Elf to turn on or off the LED_Y light of the device.
5. Reflow soldering temperature curve
When the module is over-fired, please strictly follow this temperature curve. If the temperature deviation of the reflow
soldering is too large, the module will be damaged!

2.2 List of applicable FCC rules
FCC Part 15.247
2.6 RF exposure considerations
This equipment complies with the FCC RF radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with a minimum distance of 20cm
between the radiator and any part of your body.
2.8 Label and compliance information
Remind end customers to FCC ID label on the final system must be labeled with “Contains FCC ID:
2AD56HLK-B30” or “Contains transmitter module FCC ID: 2AD56HLK-B30”.
2.9 Information on test modes and additional testing requirements
Contact ShenZhen HaiLingKe Electronic co.,Ltd will provide stand-alone modular transmitter test
mode. Additional testing and certification may be necessary when multiple modules are used in a host.
2.10 Additional testing, Part 15 Subpart B disclaimer
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 Supplier’s 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.
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.
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 separate approval is required for
all other operating configurations, including portable configurations with respect to Part 2.1093 and
difference antenna configurations.
This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.

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 product 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 product 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 product 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 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.
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 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 4: For all products market in US, OEM has to limit the operation channels to CH1 to CH11 for
802.11b/g/n-HT20 and CH3 to CH9 for 802.11n-HT40 by supplied firmware programming tool. OEM
