2.12 Application Microcontroller
The application micro-controller is used for communication channel from wireless
module to the Media box or TV, communication channel from wireless module to
Amimon base band chipset, communication channel from wireless module to IR Blaster
micro-controller, application debugging message send and receiver.
The I2C0 interface use to communicate between the media box and microcontroller. The
I2C1 interface is optional for factory mode. The purpose is registration between TX and
RX module.

Federal Communications Commission (FCC) Statement
You are cautioned that changes or modifications not expressly approved by the part
responsible for compliance could void the user’s authority to operate the equipment.
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 connected.
-Consult the dealer or an experienced radio/TV technician for help.
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 of the device of the device.
FCC Caution: for indoor use only, use outdoors or in other modes not covered by this
manual may violate the FCC regulation and violate the user authority to use the product.
Specially, within the 5.15-5.25 GHz band, U-NII device is restricted to indoor operations
to reduce any potential for harmful interference to co-channel MSS operations.
FCC RF Radiation Exposure Statement:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled
environment. This equipment should be installed and operated with minimum distance
20cm between the radiator & your body. End users must follow the specific operating
Page 13 of 15
