RE: Johnson Controls Interiors L.L.C. FCC ID: CB2UCONN2 The following is in response to comments made on the above application. 1) The test report states that the DUT antenna was rotated about all possible ways and the maximum emissions recorded. Please note that spurious emissions are not always radiated strictly by the antenna. Many times they may radiate off the device/chassis. Was the device itself also rotates sufficiently to ensure worse case emissions were determined. Note that ANSI C63.4 mentions rotating at 22.5 degree rotations when a turntable is not present. The antenna is part of the DUT PCB, and thus both were rotated together. See internal photographs. 2) FYI......Please note that it is acceptable for Bluetooth to be > 20 dB for peak to average emissions (sections 6.5). However, because of the nature of the transmissions, it is considered a pulsed emissions that should be calculated not measured. Additionally, even if average measurements were applicable, the VBW must be >= 1/Ton time, or > 335 Hz in this case. Please adjust this section of the report as necessary. Please note that the Duty Cycle presented in the report was based on your measurements. However Bluetooth has different packet lengths that may be used in modes with longer packets. The theory of operation for Bluetooth states that their may be 1, 3, or 5 slots used per transmit depending on the mode of operation. For a DH1 packet the TX is on 0.625 us per 49 mS per channel, while for a DH5 packet the TX is on 0.625 * 5 per 247 ms per channel. These duty cycles equal the following: 20 log (.625/49) = 37.9 dB or 20 log (3.125/100) = -30 dB. All are greater than the 20 dB difference between the peak and average limits. In a previous filing we were asked to provide measured verification that the DUT duty factor is greater than 20 dB below the peak emission, even though the Bluetooth protocol in its design has a duty factor greater than 20 dB.

BLUETOOTH APPROVALS The following exhibit indicates the FCC Spread Spectrum requirements in Section 15.247 for devices meeting the Bluetooth Specifications in the 2.4 GHz band as of February 2001 operating in the USA. The purpose of this exhibit is to help expedite the approval process for Bluetooth devices. This exhibit provides items that vary for each device and also provides a list of items that are common to Bluetooth devices that explains the remaining requirements. The list of common items can be submitted for each application for equipment authorization. This exhibit only specifies requirements in Section 15.247, requirements in other rule Sections for intentional radiators such as in Section 15.203 or 15.207 must be also be addressed. For each individual device, the following items, 1-7 will vary from one device to another and must be submitted. 1) The occupied bandwidth in Section 15.247(a)(1)(ii). 2) Conducted output power specified in Section 15.247(b)(1). 3) EIRP limit in Section 15.247(b)(3). 4) RF safety requirement in Section 15.247(b)(4) 5) Spurious emission limits in Section 15.247©. 6) Processing gain and requirements for Hybrids in Section 15.247(f) in the acquisition mode. 7) Power spectral density requirement in Section 15.247(f) in the acquisition mode. For all devices, the following items, 1-12, are common to all Bluetooth devices and will not vary from one device to another. This list can be copied into the filing. 1 Output power and channel separation of a Bluetooth device in the different operating modes: The different operating modes (data-mode, acquisition-mode) of a Bluetooth device don’t influence the output power and the channel spacing. There is only one transmitter which is driven by identical input parameters concerning these two parameters. Only a different hopping sequence will be used. For this reason, the RF parameters in one op-mode is sufficient. 2 Frequency range of a Bluetooth device: The maximum frequency of the device is: 2402 – 2480 MHz. This is according the Bluetooth Core Specification V 1.0B (+ critical errata) for devices which will be operated in the USA. Other frequency ranges ( e.g. for Spain, France, Japan) which are allowed according the Core Specification must not be supported by the device. 3 Co-ordination of the hopping sequence in data mode to avoid simultaneous occupancy by multiple transmitters: Bluetooth units which want to communicate with other units must be organized in a structure called piconet. This piconet consist of max. 8 Bluetooth units. One unit is the master the other seven are the slaves. The master co-ordinates frequency occupation in this piconet for all units. As the master hop sequence is derived from it’s BD address which is unique for every Bluetooth device, additional masters intending to establish new piconets will always use different hop sequences. 4 Example of a hopping sequence in data mode: Example of a 79 hopping sequence in data mode: 40, 21, 44, 23, 42, 53, 46, 55, 48, 33, 52, 35, 50, 65, 54, 67, 56, 37, 60, 39, 58, 69, 62, 71, 64, 25, 68, 27, 66, 57, 70, 59, 72, 29, 76, 31, 74, 61, 78, 63, 01, 41, 05, 43, 03, 73, 07, 75, 09, 45, 13, 47, 11, 77, 15, 00, 64, 49, 66, 53, 68, 02, 70, 06, 01, 51, 03, 55, 05, 04 5 Equally average use of frequencies in data mode and short transmissions: The generation of the hopping sequence in connection mode depends essentially on two input values: 1. LAP/UAP of the master of the connection 2. Internal master clock The LAP (lower address part) are the 24 LSB’s of the 48 BD_ADDRESS. The BD_ADDRESS is an unambiguous number of every Bluetooth unit. The UAP (upper address part) are the 24 MSB’s of the 48 BD_ADDRESS. The internal clock of a Bluetooth unit is derived from a free running clock which is never adjusted and is never turned off. For synchronization with other units, only the offsets are used. It has no relation to the time of the day. Its resolution is at least half the RX/TX slot length of 312.5 μs. The clock has a cycle of about one day (23h30). In most case it is implemented as 28 bit counter. For the deriving of the hopping sequence the entire LAP (24 bits), 4 LSB’s (4 bits) (Input 1) and the 27 MSB’s of the clock (Input 2) are used. With this input values different mathematical procedures (permutations, additions, XOR-operations) are performed to generate the sequence. This will be done at the beginning of every new transmission. Regarding short transmissions, the Bluetooth system has the following behavior: The first connection between the two devices is established, a hopping sequence is generated. For transmitting the wanted data, the complete hopping sequence is not used and the connection ends. The second connection will be established. A new hopping sequence is generated. Due to the fact that the Bluetooth clock has a different value, because the period between the two transmission is longer (and it cannot be shorter) than the minimum resolution of the clock (312.5 μs). The hopping sequence will always differ from the first one. 6 Receiver input bandwidth, synchronization and repeated single or multiple packets: The input bandwidth of the receiver is 1 MHz. In every connection, one Bluetooth device is the master and the other one is the slave. The master determines the hopping sequence (see chapter 5). The slave follows this sequence. Both devices shift between RX and TX time slot according to the clock of the master. Additionally the type of connection (e.g. single or multi-slot packet) is set up at the beginning of the connection. The master adapts its hopping frequency and its TX/RX timing is according to the packet type of the connection. Also, the slave of the connection uses these settings. Repeating of a packet has no influence on the hopping sequence. The hopping sequence generated by the master of the connection will be followed in any case. That means, a repeated packet will not be send on the same frequency, it is send on the next frequency …

BlueConnect Theory of Operation The BlueConnect module is a hands-free interface to Bluetooth enabled devices. By connecting to the vehicle bus and radio, the user is able to interact with a fully vehicle integrated system from the OEM. A voice recognition engine allows the user to control the system throughout a variety of functions. Interaction with the voice recognizer is accomplished via a microphone mounted in a manufacturer-chosen location. Further user interface (switches and voice recognizer) details are specific to the manufacturer’s preference. The primary processor of the system runs the voice recognizer as well as general function manager. The general function manager calls other functions as necessary based upon feedback from the vehicle bus, the user (via voice recognition and/or the button interface), or Bluetooth and the connected Bluetooth device(s). Memory, composed of separate RAM and FLASH, allow for reprogramming and upgrades of the system as new features are developed. The memory is also used for voice recognition libraries and other Bluetooth devices that have been paired to the system. Other user-specific features and configurations are saved here as well. A Bluetooth link to paired devices is used for the audio gateway through the system. By using the Bluetooth protocol, the module is able to connect to several different devices and route the audio out to the vehicle radio. The interface to the vehicle radio is configurable for single-ended audio, differential audio, or stereo versions of either configuration.

Brunett Valdis V. Liepa Research Scientist Summary Tests for compliance with FCC Regulations, Part 15.247, and with Industry Canada (IC) Regulations, RSS-210, Part 6.2.2, were performed on Johnson Controls model CB2UCON2 frequency hopping spread spectrum (FHSS) transmitter. The DUT is subject to the Rules and Regulations as a transmitter. In testing competed on March 11, 2004, the radiated emissions in restricted bands were met by 12.1 dB. The AC line conducted emissions tests do not apply, since the device is powered from a 12 VDC system. The DUT is exempt as a digital device since it is used in a transportation vehicle. All other testing indicates that the Johnson Controls model CB2UCON2 meets the limitations set forth by the FCC and IC for a 2.4 GHz FHSS transmitter. 2 1. Introduction Johnson Controls model CB2UCON2 was tested for compliance with FCC Regulations, Part 15, Subpart C, adopted under Docket 87-389, April 18, 1989, and with Industry Canada RSS-210, Issue 5, November, 2001. The tests were performed at the University of Michigan Radiation Laboratory Willow Run Test Range following the procedures described in ANSI C63.4-1992 "Methods of Measurement of Radio- Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz".

Configuration and Identification of Device Under Test The DUT is a frequency hopping spread spectrum (FHSS) transmitter operating in 2400 - 2483.5 MHz band. The DUT is 5 x 1.5 x 3.5 inches, and connects to a peripheral laptop computer via a serial interface card for testing purposes. The system has been designed to operate with 79 channels spaced 1 MHz apart, between 2402 MHz and 2480 MHz. The DUT has only one antenna built into the PCB. Three parts have been tested. All contain identical RF sections and differ only in the communications bus (CAN, J1850 General, J1850 Differential). The DUT was designed and manufactured by Johnson Controls Interiors L.L.C., One Prince Center, Holland, MI 49423. It is identified as: Johnson Controls Bluetooth Module Model: CB2UCON2 SN: D2C00GDA, BZC00APA, FZC0023A FCC ID: CB2UCON2 IC: 279B-UCON2 Peripheral Equipment: Laptop Computer Toshiba Satellite SN: X3058741H Model: A10-S1291 PN: PSA10U-0ZH6M3 Serial/USB Adaptor SN: Proto1 In addition to a standard unit, a modified unit was provided by the manufacturer which had the internal antenna disabled and a SMA connector attached for conducted antenna measurement purposes. 3.1 EMI Relevant Modifications No modifications were made to the DUT by this laboratory during testing. 4 4.
