It has 14 available inputs, and two available outputs. The N240D module is used to interact with an audience so they can provide real time feed back to questions. It communicates at 2.4GHz, GFSK to a base station. The base unit polls keypads, and displays result. The overall operation of the N240D module is controlled by a microcontroller. This microcontroller is powered from approximately 3V and uses a 16 MHz reference. The microcontroller handles control of the RF communications and keypad inputs. RF communications use the Nordic 2401A 2.4 GHz transceiver. The Nordic chip uses a 16 MHz reference oscillator that is shared with the microcontroller for TX/RX and is also powered by 3V. The Nordic transceiver uses an integral PCB inverted F antenna with a gain of approximately 3.6 dBi. 1.2 Keypad Battery Replacement Each keypad is powered from a single CR2032 Lithium Coin cell battery. The battery is replaceable. To replace battery, slide out the old battery from its holder, and replace with a new battery noting its polarity. The negative side of the battery should be facing the PCB. 1.3 FCC, IC, and EU Compliance Information N240D RF Module Responsible Party Pertaining to the Declaration of Conformity Fleetwood Group, Inc. 11832 James Street Holland, MI 49424 Attn: Product Service Coordinator Phone: 888-467-3759 1.4 Standards and Guidelines This device complies with the following European Directives and USA/Canada Regulations: ¾ Directive 1999/5/EC on radio equipment and telecommunication terminal equipment and the mutual recognition of their conformity ¾ Directive 2006/95/EC on the harmonization of laws of member states related to electrical equipment designed for use within certain voltage limits ¾ The USA Federal Communications Commission (FCC) Rules and Regulations ¾ Industry Canada Rules and Regulations This device complies with the following national and international standards: ¾ EN 301 489-1 V1.6.1: 2005: EMR; EMC standard for radio equipment and services.

This letter addresses each of the points numbered 1-8 on page 2 of the DA00-1407 Part 15 Unlicensed Modular Transmitter Approval. In response to: “ 1. The modular transmitter must have its own RF shielding. This is intended to ensure that the module does not have to rely upon the shielding provided by the device into which it is installed in order for all modular transmitter emissions to comply with Part 15 limits. It is also intended to prevent coupling between the RF circuitry of the module and any wires or circuits in the device into which the module is installed. Such coupling may result in non-compliant operation.” Reply: The module uses the ground plane as its RF shield to effectively control emissions. In response to: “2. The modular transmitter must have buffered modulation/data inputs (if such inputs are provided) to ensure that the module will comply with Part 15 requirements under conditions of excessive data rates or over-modulation.” Reply: Not Applicable. All modulation data inputs are internal to the module with no external electrical interface. In response to: “3. The modular transmitter must have its own power supply regulation. This is intended to ensure that the module will comply with Part 15 requirements regardless of the design of the power supplying circuitry in the device into which the module is installed.” Reply: The module is battery powered, and the transmitter uses internal constant current sources to regulate the affects of battery voltage. In response to: “4. The modular transmitter must comply with the antenna requirements of Section 15.203 and 15.204(c). The antenna must either be permanently attached or employ a “unique” antenna coupler (at all connections between the module and the antenna, including the cable). Any antenna used with the module must be approved with the module, either at the time of initial authorization or through a Class II permissive change. The “professional installation” provision of Section 15.203 may not be applied to modules.” Reply: The module uses an internal etched PCB inverted F antenna. In response to: “5. The modular transmitter must be tested in a stand-alone configuration, i.e., the module must not be inside another device during testing. This is intended to demonstrate that the module is capable of complying with Part 15 emission limits regardless of the device into which it is eventually installed. Unless the transmitter module will be battery powered, it must comply with the AC line conducted requirements found in Section 15.207. AC or DC power lines and data input/output lines connected to the module must not contain ferrites, unless they will be marketed with the module (see Section 15.27(a)). The length of these lines shall be length typical of actual use or, if that length is unknown, at least 10 centimeters to insure that there is no coupling between the case of the module and supporting equipment. Any accessories, peripherals, or support equipment connected to the module during testing shall be unmodified or commercially available (see Section 15.31(i)).” Reply: The module is battery powered and shall be tested in a stand-alone configuration. In response to: “6. The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: XYZMODEL1” or “Contains FCC ID: XYZMODEL1.” Any similar wording that expresses the same meaning may be used. The Grantee may either provide such a label, an example of which must be included in the application for equipment authorization, or, must provide adequate instructions along with the module which explain this requirement. In the latter case, a copy of these instructions must be included in the application for equipment authorization.” Reply: The module and final assembly shall comply with the stated labeling. In response to: “7. The modular transmitter must comply with any specific rule or operating requirements applicable to the transmitter and the manufacturer must provide adequate instructions along with the module to explain any such requirements. A copy of these instructions must be included in the application for equipment authorization. For example, there are very strict operational and timing requirements that must be met before a transmitter is authorized for operation under Section 15.231. For instance, data transmission is prohibited, except for operation under Section 15.231(e), in which case there are separate field strength level and timing requirements. Compliance with these requirements must be assured.” Reply: We will retain control of the module and the devices it may be installed into. In response to: “8. The modular transmitter must comply with any applicable RF exposure requirements. For example, FCC Rules in Sections 2.1091, 2.1093 and specific Sections of Part 15, including 15.319(i), 15.407(f), 15.253(f) and 15.255(g), require that Unlicensed PCS, UNII and millimeter wave devices perform routine environmental evaluation for RF Exposure to demonstrate compliance. In addition, spread spectrum transmitters operating under Section 15.247 are required to address RF Exposure compliance in accordance with Section 15.247(b)(4). Modular transmitters approved under other Se…

Rick From: Generic Office of Engineering Technology [mailto:[email protected]] Sent: Wednesday, November 07, 2007 9:34 AM To: Rick McMurray Subject: Response to Inquiry to FCC (Tracking Number 607965) Inquiry: 1) We have a product that we are certifying as FHSS under 15.247 and fixed frequency under 15.249 as a modular approval. Typical testing was performed on fixed frequencies (low, mid, high) and in hopping mode with 75 channels. We are submitting a specific pseudo random hopping table with 75 channels. May this product be used with different pseudo random hopping sequences, with the number of channels between 15 - 75 as long as the other 15.247 requirements are met? 2) May a device certified under 15.249 for a range of frequencies (test on a low, mid and high channel) switch frequencies automatically within the certified range like an FHSS device? Response: 1. yes 2. yes Do not reply to this message. Please select the Reply to an Inquiry Response link from the OET Inquiry S ystem to add any additional information pertaining to this inquiry.
