These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment offend on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. • Consult the dealer or an experienced radio/TV technician for help. CAUTION Any changes or modifications made on the system not expressly approved by the manufacturer could void the user’s authority to operate the equipment. CAUTION exposure to radio frequency radiation To comply with FCC RF exposure compliance requirements, a separation distance of at least 20 cm must be maintained between the antenna of this device and all persons. This device must not be co-located or operating in conjunction with any other antenna or transmitter. 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. model no:Xbox 360 Console trade name:Microsoft Corp. responsible party:Microsoft Corporation address:One Microsoft Way Redmond, WA 98052 U.S.A. telephone no.:(800) 4MY-XBOX 4 english for Customers in Canada This Class B digital apparatus complies with Canadian ICES-003. This device complies with RSS 210 of Industry Canada (IC). 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 this device. CAUTION exposure to radio frequency radiation The installer of this radio equipment must ensure that the antenna is located or pointed such that it does not emit RF field in excess of Health Canada limits for the general population; consult Safety Code 6, obtainable from Health Canada’s website at www.hc-sc.gc.ca/rpb. 5 english lImIteD Warranty anD return InformatIon Do not attempt repairs Do not attempt to take apart, open, service, or modify the Xbox 360 console, power supply, or accessories. Doing so could present the risk of electric shock, fire, or damage to your Xbox 360 console. Any evidence of any attempt to open and/or modify the Xbox 360 console, including any peeling, puncturing, or removal of any of the labels, will void the Limited Warranty and render the Xbox 360 console ineligible for authorized repair. a. WarrantIeS • One Year Express Warranty on Console (three years for three lights flashing red).

Microsoft Corporation FCC ID: C3K1400 Request for transmitter modular approval Transmitter Module Characteristics Item Requirements EUT 1 The module has its own RF shielding Device is equipped with Metal shielding to cover RF section. Refer to external photos 2 All modulation and data input(s) are buffered. All inputs to the modules are buffered through logic or microprocessor inputs. 3 The module has its own power supply regulation and local reference oscillator. Internal 1.8V power regulator. 40 MHz crystal provides reference frequency to SoC to generate LO frequencies. 4 Comply with antenna requirements of Section 15.203 and 15.204(c) Antennas are permanently connected and non replaceable by the user. 5 The host device, as a stand-alone unit without any separately certified modules, complies with all applicable Radio Standards Specifications. Device was tested standalone with Laptop as support device. See setup photographs 6 The host device complies with the certification labeling requirements of each of the modules it contains. Refer to label format exhibit. 7 The modular transmitter is manufactured so that the user cannot influence the operation of the transmitter that will operate outside of the scope of the regulations. There are no adjustments or user accessible controls in hardware or software that will influence operation of the transmitter. 8 Address compliance with the Commission’s RF exposure limits in Sections 1.1310 and 2.1093. 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) Refer to RF exposure calculation exhibit.

MAXIMUM PERMISSIBLE EXPOSURE FCC RULES §1.1310 The criteria listed in Table 1 shall be used to evaluate the environmental impact of human exposure to radio-frequency (RF) radiation as specified in §1.1307(b), except in the case of portable devices which shall be evaluated according to the provisions of §2.1093 of this chapter. REPORT NO: 09U12915-1C DATE: MARCH 25, 2010 FCC ID: C3K1400 IC: 3048A-1400 Page 201 of 211 COMPLIANCE CERTIFICATION SERVICES FORM NO: CCSUP4701C 47173 BENICIA STREET, FREMONT, CA 94538, USA TEL: (510) 771-1000 FAX: (510) 661-0888 This report shall not be reproduced except in full, without the written approval of CCS. IC RULES IC Safety Code 6, Section 2.2.1 (a) A person other than an RF and microwave exposed worker shall not be exposed to electromagnetic radiation in a frequency band listed in Column 1 of Table 5, if the field strength exceeds the value given in Column 2 or 3 of Table 5, when averaged spatially and over time, or if the power density exceeds the value given in Column 4 of Table 5, when averaged spatially and over time. REPORT NO: 09U12915-1C DATE: MARCH 25, 2010 FCC ID: C3K1400 IC: 3048A-1400 Page 202 of 211 COMPLIANCE CERTIFICATION SERVICES FORM NO: CCSUP4701C 47173 BENICIA STREET, FREMONT, CA 94538, USA TEL: (510) 771-1000 FAX: (510) 661-0888 This report shall not be reproduced except in full, without the written approval of CCS. EQUATIONS Power density is given by: S = EIRP / (4 * Pi * D^2) where S = Power density in W/m^2 EIRP = Equivalent Isotropic Radiated Power in W D = Separation distance in m Power density in units of W/m^2 is converted to units of mWc/m^2 by dividing by 10. Distance is given by: D = SQRT (EIRP / (4 * Pi * S)) where D = Separation distance in m EIRP = Equivalent Isotropic Radiated Power in W S = Power density in W/m^2 For multiple colocated transmitters operating simultaneously in frequency bands where the limit is identical, the total power density is calculated using the total EIRP obtained by summing the Power * Gain product (in linear units) of each transmitter. Total EIRP = (P1 * G1) + (P2 * G2) + ... + (Pn * Pn) where Px = Power of transmitter x Gx = Numeric gain of antenna x In the table(s) below, Power and Gain are entered in units of dBm and dBi respectively and conversions to linear forms are used for the calculations.
