Therefore, the chip provides users with a low-cost, high-performance ZigBee solutions. Rev. 0.0.9 2 / 6 4.2 Antenna VC4SMN512 default connection board PCB antenna, Users can also choose to connect an external antenna via zero ohm resistor. In order to guarantee the transmission performance, it can not exist around the module ground plane.When using an extenna antenna,you need to pay attention to the antenna lead-out portion of the motherboard design..Ensure the transmission line impedance matching. Avoid the impedance mismatch caused by radio signal reflection, the actual antenna signal power drops, affect the transmission distance. 5 Pin Description Figure5.1.VC4SMN512 pin descriptions Table 5.1.pin descriptions PIN#

tions: (1) This device may not cause harmful interference, and (2) this device must accept any interfe-
rence received, including interference that may cause undesired operation. Inormation to user Note: This equipment 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 equipment 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 equipment 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 con-
nected.
-Consult the dealer or an experienced radio/TV technician for help. Note: The Grantee is not re-
sponsible for any changes or modifications not expressly approved by the party responsible for com-
Rev. 0.0.9 5 / 6 pliance. such modifications could void the user's authority to operate the equipment. the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed IMPORTANT NOTE: In the event that these conditions cannot be met (for example co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. Manual Information To the End User:
The OEM integrator has to be aware not to provide information to the end user regarding how to in-
stall or remove this RF module in the user's manual of the end product which integrates this module. Modular Approval:
The VC4SMN512 module is designed to comply with the FCC statement. FCC ID is 2ATL8VC4SMN512. The host system using VC4SMN512, should have label indicated it contain mod-
ular's FCC ID 2ATL8VC4SMN512. RF warning:
The device has been evaluated to meet general RF exposure requirement. To maintain compliance with FCC's RF exposure guidelines, the distance must be at least 20 cm between the radiator and your body, and fully supported by the operating and installation configurations of transmitter and its anten-
na(s). Rev. 0.0.9 6 / 6
