1.0 Test Summary TEST REPORT: #151107 COMPANY: Starkey Laboratories, Inc. AGENT: International Certification Services, Inc. PHONE: 320-864-4444 TEST DATE: 15 Novmber, 2007 EQUIPMENT UNDER TEST: nEARcom with OTICON plug in Model: TM1 GENERAL TEST SUMMARY: The testing was performed at International Certification Services, Inc. at 1100 Falcon Ave, Glencoe, MN 55336 VERIFICATION / CERTIFICATION The 3.8 Mhz transmitter was found to be in compliance STATUS: with the FCC Part 15 Subpart C, Section 15.223 requirements. MODIFICATIONS NECESSARY: None TESTED BY WRITTEN BY Steve Wendlandt Duane R. Bagdons International Page 4 of 20 Certification Services, Inc.

2.0 Applicable Standards 47 CFR Ch.1 (10-1-98 Edition) FCC Part 15 Radio Frequency Devices Subpart C Intentional Radiators Section 15.223 Operation in the band 1.705 - 10 Mhz 2.1 Referenced Standards ANSI C63.4-2003 Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 Khz to 40 Ghz. 2.2 Equipment Units Tested The equipment tested was a battery powered 3.8 Mhz transmitter that is part of the Starkey Laboratories, Inc. Wireless Hearing Aid Programming Adaptor nEARcom product. The nEARcom product is the base platform that allows up to 5 different wireless Technology plug in Modules to operate. The Wireless Technology Modules plug into the nEARcom. The intentional radiator is located in each of the Wireless Technology Modules. This report is for the nEARcom unit with an Oticon TM1 plug in module installed. There is no external antenna involved, the TM1 plug in module contains its own internal antenna on its PC board. The Intentional Radiator operates at a frequency of 3.85172 Mhz and is tested against the FCC Part 15.223 section of the FCC Part 15 standard. The Wireless Technology Module is strictly battery operated and is powered from the nEARcom base platform called the NOAHlink. 2.3 Equipment and Cable Configuration See photo of the EUT test configuration setup in Attachment A 2.4 List of Test Equipment Test Equipment Model S/N Calibration Date Spectrum Analyzer Hewlett-Packard 8566B 2421A00458 07/17/06 Preamp P0024 N/A 04/04/07 Preamp CLC102 22773 04/04/07 Biconical Antenna EMCO Model 93110B 105799 03/30/07 Log Periodic Antenna EMCO 3146 9111-3280 03/30/07 (200-1000 MHz) Monopole Antenna EMCO 3301B 2095 07/19/06 Loop Antenna EMCO 6512 8912-1074 03/30/07 Measurement cable losses, and antenna correction factors are included in the data sheets. The Resolution BW was set at 10 Khz and the Video BW was set at 30 Khz. 2.5 Units of Measurement. All measurements were taken in dBuV/m and frequency measurements are recorded in Mhz. The receiving antenna was positioned at a distance of 1 meter and then 0.5 meters from the International Page 5 of 20 Certification Services, Inc.

EUT for measuring the Intentional Radiator signal. The difference in distances was because the EUT produced such a small signal that the antenna had to be moved in closer to it to measure the signal. 2.6 Location of Test Site The open area test site (OATS) measurement facility used to collect the data was International Certification Services, Inc. at 1100 Falcon Ave in Glencoe, MN 55336. This site has been certified to be in spec of the normalized site attenuation per ANSI C63.4-2003. See letter of compliance from FCC dated July 23, 1998. (FCC 31040/SIT 1300F2) 2.7 Measurement Procedures All recorded data was taken with a NEW battery installed in the device under test as required by FCC 15.31 (e). Also the antenna distance of 0.5 meter was used for all recorded data from 0.01 to 30 Mhz and then the data was corrected to the proper antenna distance required by FCC 15.223 and FCC 15.209 using a correction factor of the square of an inverse linear distance extrapolation factor (40 dB per decade) as required by FCC 15.31 (f) (2). The requirements of FCC 15.223 are as follows: FCC 15.223 The field strength of any emission within the band 1.705-10.0 MHz shall not exceed 100 microvolts/meter at a distance of 30 meters. “However, if the bandwidth of the emission is less than 10% of the center frequency, the field strength shall not exceed 15 microvolts/meter or (the bandwidth of the device in kHz) divided by (the center frequency of the device in MHz) microvolts/meter at a distance of 30 meters, whichever is the higher level. For the purposes of this Section, bandwidth is determined at the points 6 dB down from the modulated carrier.” Fundamental Frequency = 3.83 Mhz 10% of this frequency = 38.3 Khz Frequency (Mhz) (-6dB point) Frequency (Mhz) (+6dB point) Bandwidth (kHz) 3.798 3.868 70 The 6 dB bandwidth of the NearCom TM1 is 42 Khz. This bandwidth is greater than 10% of the fundamental frequency therefore the limit is either 15 uV/m or 70 Khz/3.83 Mhz = 18.277 uV/m. Since 18.277 uV/m is greater than 15 uV/m the allowable limit is 18.277 uV/m for this device measured at 30 meters.

November 15, 2007 Figure 4 FCC 15.209 Radiated Emissions The antenna was placed at a distance of 0.51 meter from the EUT for frequencies below 30 Mhz and a distance of 10 meters from 30 to 1000 Mhz. The EUT was set on an insulating table in the OATS site and rotated through 360 degrees to determine the worst case EUT orientation. The Loop antenna was used for frequencies below 30 Mhz and above 30 Mhz a BiCon and Log Periodic Antenna was used. No EUT signals were detected throughout the frequency range of 30 to 137 Mhz. 2.1046 RF Power Output This device does not have antenna terminals; the antenna is built into the PC board. Also, there is no transmitter tuning designed into this system. The transmitter power output is permanently International Page 9 of 20 Certification Services, Inc.

This parameter was not measured; instead the output field strength already reported above in section 15.223 shows the output levels of this EUT. 2.1047 Modulation Characteristics The plot below shows the modulation characteristics of the transmitted signal.

2.1049 Occupied Bandwidth The Peak Output level measured at 3.82159 Mhz is –8.6089 dBuV/m (0.371 uV) and the level at where the output level goes asymtotic to the ground floor noise is at 3.17619 Mhz (as opposed to the band limit of 1.705 Mhz and 10 Mhz) and that level is already –39.38917 dBuV/m (0.010729 uV). This is 0.5% of the mean radiated power. Starkey Laboratories, Inc.

November 15, 2007 Figure 7 EUT Harmonics 2.1055 Frequency stability The operating frequency of the EUT was measured at the extremes of the specified temperature range and at intervals of not more than 10 deg Centigrade through the range. A period of time sufficient to stabilize all of the components of the oscillator circuit at each temperature level was allowed prior to frequency measurements. There were no short-term transients effects on the frequency of the transmitter due to keying or any heating elements cycling normally occurring at each ambient temperature level. The whole EUT was immersed in the thermal chamber for this test. The frequency stability was measured at a minimum battery voltage level specified by the manufacturer.

Testing was performed from 9 kHz to 1000 Mhz which more than adequately covers the required range. 3.0 Radiated Emissions Data The frequency and amplitude of the tuned frequency of the EUT along with the frequencies and amplitudes of the harmonics up to the 10th harmonic are reported in the data sheets in Attachment B. The Final Level, expressed in dBuV/m, is arrived at by taking the reading from the spectrum analyzer (Level dBuV) and adding the antenna correction factor and cable loss factor (Factor dB) and subtracting the preamp gain. This result then has the FCC limit subtracted from it to provide the margin which gives the tabular data as shown in the data sheets in Attachment B. Example: Frequency Level + Factor = Corr Data - FCC Limit = Margin (MHz) (dBuV) + (dB) = (dBuV/m) - (dBuV/m) = (dB) 100.0 20.6 + 11.0 = 31.6 - 43.5 = -11.9 International Page 13 of 20 Certification Services, Inc.
