Bluetooth wireless technology is a high frequency radio link that allows two Bluetooth devices to exchange audio information and data at high speed. Because of the versatility of Bluetooth wireless technology, enabled devices do not share all of the same "profiles." To ensure that your phone will be compatible with your HFM, be sure to purchase a cellular phone that supports the "Dial-up Networking" profile. Precautions Warning: When preparing to set up the HFM, be sure the vehicle involved is in park with the engine turned off. Setting up Your HFM Note: Most vehicles require the ignition switch to be turned to the second (or "accessory") position for programming and/or operation of the HFM. The radio must be turned on to hear HFM audio. It is also recommended that your cell phone's battery be fully charged to ensure that the Bluetooth connection will be established with minimal difficulty. To use the voice recognition software, face the windshield and speak clearly in your normal voice (do not shout). Note: The voice recognition software expects you to speak in a natural voice. Do not try to "help" the voice recognition software by speaking slowly or by pronouncing words more distinctly than you normally do. Pairing In order for your HFM to work with your Bluetooth phone, you must first pair the two devices. To pair a phone to HFM: 1. Press and release HFM's Phone button. 2. After you hear the "Ready" prompt, say "Setup, Registration." 3. The HFM will prompt, "Do you want to register a phone, clear a phone, or list available phones?" Say "Register." 4. Refer to your cellular phone user's manual for further information on pairing your phone to HFM. Clearing Paired Phones To re-prioritize the cell phones being used, you must first clear the phone(s) paired with HFM. Note: If you make a mistake during the clearing process or decide not to clear a phone, press either HFM's Phone button or VR button to exit the clearing mode. To clear paired cell phones from the HFM's memory: 1. Press and release HFM's Phone button. 2. After you hear the "Ready" prompt, say "Setup, Registration." 2 3. The HFM will prompt, "Do you want to register a phone, clear a phone, or list available phones?" Say "Clear." 4. The HFM will prompt, "Which phone would you like to clear or say all to clear all phones?" 5. Say the phone's voicetag (such as "Rich's Phone") to clear one phone or say "All" to clear all paired phones. 6. The HFM responds with "Removing all, is this correct?" if you chose to clear all phones or it responds with "Removing Rich's Phone, is this correct?" if you chose to clear an individual phone (such as Rich's Phone). 7. Say "Yes". The HFM responds with "C…

ATCB RE: Johnson Controls Interiors L.L.C. FCC ID: CB2UCONN The following is in response to the comments provided for the CB2UCONN filing. 1) Please provide a photograph that shows the complete back of the Bluetooth TX board. An Addendum to the Internal Photos test exhibit has been uploaded. 2) Please provide an updated label that includes the correct FCC ID for this application. An updated label has been uploaded. 3) The device appears to contain 2 or 3 different boards. Please provide a description of what each board is. The DUT includes two PCB boards. The primary board contains the Bluetooth transmitter and additional digital circuitry which connects the DUT to the automotive buss. The smaller secondary board contains the digital electronics which control the Bluetooth coding and decoding operations. 4) Please provide radiated spurious emissions test photographs. A test photograph of the radiated emissions setup is already available in the Test Setup Photos exhibit. 5) Please provide a separate RF exposure exhibit. Please be sure to include information regarding how the device is expected to be mounted within a car and the distance the antenna is from users once installed. Also, please provide MPE calculations as these are still desired even with the low power output. As per conversations with Bill Graff at ATCB about this device, we were told that for a device of EIRP less than 10 mW we would not be required to submit RF exposure calculations as the DUT “operates at substantially low output power levels, with a low gain antenna” as is stated in the Public Notice on Filing and Measurement Guidelines for FHSS Systems you forwarded to use with this request. If this is incorrect please let us know for future reference. We have uploaded a RF Exposure exhibit if it is still deemed necessary. 6) The users manual provided contains statements regarding confidentiality. Please note that the users manual is not typically allowed to be considered confidential, since the end user is expected to receive a copy anyway. Please comment. Disregard the Confidentiality statement in the User’s Manual. 7) Section 6.4 shows data and a limit for a 1 second. Please note that the limit specified is over a 30 second period of time. Please adjust the data given in this section. Additionally, depending on the amount of data the unit is sending, it likely will not transmit full packets and will provide data less than expected. Refer to Theory of operation that we sent to you earlier. This has been corrected. See the revised test report we have included. 8) Section 6.5 & 6.6 of the test report states that average measurements were made using a 1 Hz VBW. The FCC only accepts an average measurement of 10 Hz or greater. Additionally, average measurements with the hopping enabled are NOT allowed. To obtain an average measurement, the following must be employed: 1) Measure the signal with hopping DISABLED using RBW = 1 MHz, VBW = 10 Hz. 2) Determine worse case duty cycle in any 100 msec of time. Please note that Bluetooth offers several different length packets depending on amount of data to send. Subtract the correction factor of 20 log (maximum transmit time in 100 msec/100) from 1) above. A 1Hz VBW was a typo in section 6.5 of the test report. All average data was taken with 100 Hz VBW as stated in section 6.6. This has been corrected in the revised test report. 9) The EUT should NOT be hopping for power measurements. Please provide new peak data (with hopping disabled and also for a typical low, middle, and high channels) for section 6.6 of the test report and also adjust the 731 form if necessary. Additionally, we have provided a document regarding testing of FHSS devices that you may find useful. Please note outline areas of document regarding hoping or being hop stopped. The power levels for the device in non-hopping mode have been included in the revised test report. Note there was no change in output power levels from the DUT. 10) The EUT should NOT be hopping for RF Antenna Conducted measurements. Please provide new peak data (with hopping disabled and also for a typical low, middle, and high channels) for section 6.6 of the test report. This has been corrected. See the revised test report we have included. 11) Bandedge compliance should be measured for both a hopping and non-hopping mode of operation. Please provide new data for the bandege that checks both modes of operation. This has been corrected. See the revised test report we have included.

ATCB RE: CB2UCONN The following is in response to your request for further information regarding the submission/certification of FCC ID: CB2UCONN. 1) The RF exposure calculations provided show an antenna gain of 1 dBi, while section 6.7 of the test report state an antenna gain 0 dBi. Please correct the exhibits to be consistent. This has been corrected. Please see updated Test Report. 2) The RF exposure calculations should be shown for the highest output power. Please correct this exhibit for the output power of 4.7 dBm (2.95 mW). This has been corrected. Please see updated RF Exposure exhibit. 3) 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. However, since average measurements where not made and you are relying on this justification, it is recommended that reference to this fact that all types of transmissions in Bluetooth yield a correction factor > 20 dB. A reference to the statement included in the attestations portion of the filing has been included in the revised test report. 4) Your response stated that for antenna conducted measurements was included in the new revision of the report for a low, middle, and high channel. However, section 6.9 of the Test report states that the hopping was enabled and data was provided for all channels. This has been corrected. Please see updated Test Report.

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.

One Prince Center Holland, MI 49423 Contact: Craig Harder Tel: 616-394-6101 Fax: 616-394-3877 PO: Verbal Tests supervised by: Measurements made by: Report approved by: _____________________ Joseph D. 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 U-connect frequency hopping spread spectrum (FHSS) Bluetooth transmitter. The DUT is subject to the Rules and Regulations as a transmitter. In testing competed on 17-Oct-02, the radiated emissions in restricted bands were met by 11.8 dB. The AC line conducted emissions tests do not apply, since the device is powered from a 12 VDC automotive 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 U-connect meets the limitations set forth by the FCC and IC for a 2.4 GHz FHSS transmitter. 2 1. Introduction Johnson Controls model U-connect 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". The Site description and attenuation characteristics of the Open Site facility are on file with FCC Laboratory, Columbia, Maryland (FCC Reg. No: 91050) and with Industry Canada, Ottawa, ON (File Ref.
