OEM Labeling Requirements:
NOTICE:The OEM or final integrator must ensure that FCC labeling requirements are
met.This includes an additional label on the outside of the final product housing
with the following contents:
Company Name：ＸＸＸＸ
MODEL: ＹＹＹＹ
Contains Model: LSD4WF-2MD05106(XXXXY) FCC ID:N8NLSD4WF2MD05106
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.
To satisfy FCC RF Exposure requirements for this transmission devices, a
separation distance of 20 cm or more should be maintained between the antenna of this
device and persons during operation. To ensure compliance, operation at closer than
this distance is not recommended. The antenna(s) used for this transmitter must not
be co-located or operating in conjunction with any other antenna or transmitter.

7. Referencedesign
PCB onboard antenna is built in LSD4WF-2MD05106 module, users should using onboard antenna
design need to be cautious that：
1, No components or GND on antenna area of user board
2, Keep antenna away from metal, stay over 10mm away from surrounding higher components.
3, Antenna can’t be covered by metal case and it should be over 10mm away from plastic casing.
During specific design, users can consult the Lierda technical engineer to assist in the place of the
module and related Layout.
8. Developingtool
Lierda would provide a complete set of LSD4WF-2MD05106 development kit for customers to get
familiar with the application and development of the module. Users can configure and debug the
parameters of the LSD4WF-2MD05106 module through the USB interface and the function test. This
development board can directly get power from the USB interface, it also support lithium battery and DC
5~18V DC current supply, convenient for the user.
