FCC 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 transmitter must not be co-located or

operating in conjunction with any other antenna or transmitter. Notice: Any changes

or modification not expressly approved by the party responsible could void the user’s

authority to operate the device.

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 undersired operation.

The Bluetooth Module allows a speakers with a communicate with other

Bluetooth-enabled devices. When used with the Bluetooth application software, it can

perform wireless network application such as information exchange, file transfer,

network access, dial-up networking, headset audio gateway, and so on.

General Description

The apm1883 Bluetooth audio transceiver provides off-the-shelf wireless function

for class1 and class2 stereo audio application. It consists of apm1882 Bluetooth audio

module, PA/LNA, RF switch and LPF with a compact size of 45mm by 26mm for class1

solution. The apm1882 integrates Broadcom’s ZV4301 Bluetooth chip, Wolfson’s

WM8731 CODEC, crystal and Flash memory on a single module. It could be easily

embedded into audio system for Bluetooth wireless communication.

The specified profiles and firmware are pre-loaded into the built-in flash memory of

apm1882 module for Bluetooth audio transmission and receiving. The user could

update the firmware version by using the UART interface test point connect to host PC.

This equipment has been tested and found to comply with the limits for a Class B

digital device, pursuant to Part 15 of 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. If not installed and used in accordance with the instructions, 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 tuning the equipment off and on, the user is

encouraged to try and correct the interference by one or more of the following

measures:

- Reorient or relocate the receiving antenna

- Increase the distance between the equipment and the receiver.

- Connect the equipment to outlet on a circuit different from that to which the

receiver is connected.

- Consult the dealer or an experienced radio/TV technician for help.

Information for OEM integrator The OEM integrator has to be aware not to

provide information to the end user regarding how to install or remove this RF

module in the user manual of the end product. The user manual which is

provided by OEM integrators for end users must include the following information

in a prominent location. “To comply with FCC RF exposure compliance

requirements, the antenna used for this transmitter must be installed to provide a

separation distance of at least 20 cm from all persons and must not be

co-located or operating in conjunction with any other antenna or transmitter.”

Label for end product must include “ Contains FCC ID: SETAPM1883 ” or “ A RF

transmitter inside, FCC ID: SETAPM1883 ”.

TO OEM installer:

1. FCC ID label on the final system must be labeled with “Contains FCC ID:

22

SETAPM1883”

2. In the user manual, final system integrator must be ensure that there is no

instruction provided in the user manual to install or remove the speakers.

3. Audio module must be installed and used in strict accordance with the

manufacturer’s instruction as described in the user documentation that comes

with the product.

This device complies with the following radio frequency and safety standards.

The user manual of the final host system must contain the following statements:
