Introduction The user manual contains information pertaining to output power, operating frequency, operating channels, data rates, tuning range, intended use, general installation instructions, and antenna connector and gain information. . 2.4GHz Transmitter Version: 1.0 User Interface Specification Date: 12/12/2011 10:41:00 AM Confidential © Traxxas 2009 Page 6 of 8 2. Users Guide Information It is required that Traxxas LLP place the text below in the product user guide along with all other pertinent regulatory information. We are only using the module on our own motherboard, and there is sufficient filtering on the module for the supplied voltage supply. The requirements for FCC Limited Modular Approval were released in March 2009 in the FCC’s Public Notice: FCC Public Notice DA-08-672, Part 15 Unlicensed Modular Transmitter Approvals. Design Criteria for Modular Approval General Conditions: The following conditions must be strictly adhered to for modular approval: 1. No modification to the module including the circuitry is permitted. 2. Design criteria to include antenna, interconnects, and local oscillator. 3. Testing of the final device configuration for Digital Emissions Compliance The Spectrum 2.4Ghz, TX Board may not be altered or modified in any manner by the OEM or other entity. Additionally, no component may be added which could change the radio frequency (RF) characteristics. These include, but are not limited to unintentional or spurious emissions, immunity, ESD characteristics, or other items commonly associated with RF devices. This includes all components; passive and active. Additionally, no RF components may be placed between the RF output of the module and the antenna. 2.1 Antenna Regulation The antenna has been selected and specifically tested with the Spectrum 2.4GHz, TX Board, and has been certified through the regulatory agencies in the US and European Union authorized use. Use of any other antenna type used with this unit voids the LMA grant for the said module. 2.2 Emissions Compliance Testing Notwithstanding the Modular Approval for the device with associated antenna, the end product configuration must meet digital emissions compliance and must be tested in accordance with FCC Part 15 requirements confirming radiated emissions are within specified limits. Applicable FCC guidelines: • Part 15 Section 15.109 Sub-paragraph A, Class B Radiated Emission Limits. 2.4GHz Transmitter Version: 1.0 User Interface Specification Date: 12/12/2011 10:41:00 AM Confidential © Traxxas 2009 Page 7 of 8 These emission tests can be conducted by the manufacturer or by contacting an approved test facility equipped and certified accordingly. The results of these emissions tests are not required to be submitted to the FCC or Traxxas, but should be kept on file by the OEM. 2.3 Working with Additional Transmitters The Spectrum 2.4GHz, TX Board should not be operated with any other transmitter in the end product. However, if such an application comes about, further regulatory compliance from the FCC must be obtained. 2.4 Product Labeling Requirements FCC product labeling requirements stipulate an FCC label, including specific text, be placed on the device containing the module. The product label must include the following text and must be affixed to the exterior of the final product. The text should be located beneath the FCC compliance logo. This product contains the Spectrum 2.4GHz, TX Board FCC ID: XVE-SA10044 In addition to the above text FCC Part 15.21 stipulates that the Digital Electronic Devices manufacturers must also have the following statements printed in their user/operations manual and/or indicate this exact text on the side of the final 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 undesired operation. Caution: Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment. Note: The manufacturer is not responsible for any radio or TV interference caused by unauthorized modifications to this…

Having the subject information easily available to "competition" would negate the advantage they have achieved by developing this product. Not protecting the details of the design will result in financial hardship. Permanent Confidentiality: The applicant requests the exhibits listed above as permanently confidential be permanently withheld from public review due to materials that contain trade secrets and proprietary information not customarily released to the public. Short-Term Confi dentiality: The applicant requests the exhibits selected above as short term confidential be withheld from public view for a period of 180 days from the date of the Grant of Equipment Authorization and prior to marketing. This is to avoid premature release of sensitive information prior to marketing or release of the product to the public. Applicant is also aware that they are responsible to notify ACB in the event information regarding the product or the product is made available to the public. ACB will then release the documents listed above for public disclosure pursuant to FCC Public Notice DA 04-1705.
