All receiving equipment conforms to CISPR Publication 16-1, Radio Interference Measuring Apparatus and Measurement Methods. 3.3 LABORATORY ACCREDITATIONS AND LISTINGS The test facilities used to perform radiated and conducted emissions tests are accredited by National Voluntary Laboratory Accreditation Program for the specific scope of accreditation under Lab Code: to perform Electromagnetic Interference tests according to FCC PART 15 AND CISPR 22 requirements. No part of this report may be used to claim or imply product endorsement by NVLAP or any agency of the US Government. In addition, the test facilities are listed with Federal Communications Commission (registration no: and 90471). Page 5 Rev. 00

7 4. EN REQUIREMENT 4.1 HUMAN EXPOSURE TO THE ELECTROMAGNETIC FIELDS LIMIT Systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy levels in excess of the following limits. For frequency range 10 MHz to 10 GHz The basic restriction at frequencies between 10 MHz and 100 GHz is on localized SAR in the head. Any device with output power below 20 mw cannot produce an exposure exceeding this restriction under the most pessimistic exposure conditions. The basic restriction is 2 W/kg so any unit which supplies less than 20 mw (=2/100W) from its antenna port, averaged over 6 minutes, will meet the basic restriction. For frequency range 10 GHz to 300 GHz The most conservative assumption is that all the transmitted power is absorbed within the specified area, therefore any device which supplies less than 20 mw will meet the basic restriction. The average time is equal to 68/f munutes (where f is in GHz) In the frequency range 10 GHz to 300 GHz, the basic restriction is 10 Wm -2 averaged over any 20 cm 2 of exposed area with a spatial maximum of 200 Wm -2 averaged over 1 cm 2 Criteria A: All electromagnetic fields If the average power emitted by apparatus operating in the frequency range 10 MHz 300GHz is less that or equal to 20 mw and the transmitting peak power is less than 20W then the apparatus is deemed to comply with the basic restrictions without testing. Averaging time is 6 minutes in the frequency range 10 MHz to 10 GHz. The average time is equal to 68/f minutes (where f is in GHz) in the frequency range 10 GHz to 300 GHz. If the total supply power or the input power to the circuitry producing the greatest emissions in the device is less than or equal to 20 mw then it is assumed that the emitted power is less than 20 mw. Criteria B: Pulse modulated electromagnetic fields with pulse duration less than 30 microseconds For pulses of duration less than 30 microseconds at frequencies between 300 MHz and 10 GHz, there is also a basic restriction on Specific energy absorption (SA). This is 2mJ kg -1 in any 10g of tissue in the head. For most pulses, the SAR restriction will be more stringent, but for pulses with a repetition frequency of less than 100 Hz, the SA restriction will predominate. For devices producing pulses with repetition rates below 100 Hz, the average power should be less than 20 x prf mw (pulse repetition frequency, prf in Hz). TEST RESULTS No non-compliance noted Since average output power at worst case is IEEE802.11b: 18.57dBm (0.0719W) / IEEE802.11g: dbm ( W) which exceed the exempt condition, 20mW specified in EN RF exposure assessment has been performed below to prove that this unit will not generate the harmful EM emission above the reference level as specified in EC Council Recommendation (1999/519/EC).

8 4.2 HUMAN EXPOSURE ASSESSMENT EUT parameter (data from the separate report) Max average output power in Watt (TP) IEEE b: dbm (0.0719W) IEEE g: dbm ( W) Antenna gain (G) IEEE b/g: 2.8 dbi (Numeric gain: 1.91) E-field strength (V/m) 61V/m Exposure evaluation Given G TP E = 30 D G TP D = 30 E Where G: numerical gain of transmitting antenna; TP: Transmitted power in watt; D: distance from the transmitting antenna in meter. IEEE b: Yield D = = m 61 G TP(W) E(V/m) D(m) IEEE g: Yield D = = m 61 G TP(W) E(V/m) D(m) Conclusion: D= m is the minimum distance between the EUT and human body to meet the E-field strength of 61V/m as required in Annex III table 2 of EC Council Recommendation (1999/519/EC). This proves that the unit complies with the EN50371 for RF exposure requirement. Page 8 Rev. 00
