FCC STATEMENT

This device complies with Part 15 of the FCC Rules. Operation 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

INDUSTRY CANADA STATEMENT

This device complies with Industry Canada licence-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device.

Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement.

RF Exposure - Min. 20 cm separation distance required for this module.

2.4 GHz statement – The radio module only supports Channels 2412, 2438, 2464 MHz and does not support Channel frequencies 2467 MHz or 2472 MHz.

5 GHz UNII statement – This module supports automatic discontinue transmission as described in

15.407(c):

“The device shall automatically discontinue transmission in case of either absence of information to transmit or operational failure. These provisions are not intended to preclude the transmission of control or signalling information or the use of repetitive codes used by certain digital technologies to complete frame or burst intervals.”

When the module is configured as a “Master” device, it will transmit digitally encoded audio data as fed from the host system via an I2C data bus. If this data is malformed as indicated by an incorrect data checksum. Transmission ceases. When configured as a “Slave” device, the only transmissions occur after the reception of a data packet from the Master. Lack proper data reception, a single transmission of “Not Acknowldge” to inform the master of the failure. Lacking pairing with a Master device, the module is in receive only mode.

Frequency stability 15.407(g).

“Manufacturers of U-NII devices are responsible for ensuring frequency stability such that an emission is maintained within the band of operation under all conditions of normal operation as specified in the users manual.”

This is accomplished by through the use of a crystal controlled oscillator having a frequency tolerance of 20 parts per million in accuracy. This frequency is verified at manufacture to be within these tolerances.

Labeling - For a host manufacture’s using this certified modular, an additional permanent label referring to the enclosed module: “Contains Transmitter Module FCC ID: A94410128RM and IC: 3232A-420128RM” or “Contains FCC ID: A94410128RM and IC: 3232A-420128RM” must be used. The host OEM user manual must also contain clear instructions on how end users can find and/or access the module and the FCC ID.
