Test report #0500814B FCC 15.231 for 1800-TIM-TW4 FCC ID: IVS1800TIMTW Tested Sep 21, 2005 Summary of Results: 1. This test series evaluated the Equipment Under Test to FCC Part 15.231b for intermittent control signal. The EUT is manually operated by momentary push button with a hold over time of less than 0.1 seconds after release as shown in the plot in the formula 3 section. 2. The system tested is compliant to the requirement of CFR 47, FCC Part 15, SubPart C for intermittent control signal operation in the allowed frequency bands outside of 410- 470MHz band, (Part 15.231b). 3. The equipment under test was received on Sep 21, 2005 and this test series commenced on Sep 21, 2005. 4. The unit operates only at the frequency 433.92MHz. 5. The Occupied Band width of the fundamental, with a 30 KHz RBW, measured 185 KHz. 6. The field strength level of the fundamental was measured with corrected average detection* and observed to be 77.8dBuV/m which is 3dB below the limit of 80.8dBuV/m. The EUT was positioned on the ‘Flat side’ and the receive antenna oriented in the horizontal polarization. 7. The evaluation of the field strength levels of the transmitter harmonics showed the emission nearest the FCC limit occurred at 4339MHz. This signal was measured to be 8.05dB below the average limit of 54dBuV/m. The EUT was configured in the ‘side’ position, and the receive antenna oriented in the vertical polarization. 8. Spurious emissions, not harmonics of transmitter, were initially characterized in a shielded enclosure. At the open area test site the spurious emission level nearest the limit occurred at 51.3MHz in the vertical polarization. This emission was measured to be 30.8BuV/m Quasi-Peak which is 9.2dB below the limit of 40dBuV/m (100uV/m) and 27dB below 20dBC limit of 57.8dBuV/m. 9. The line conducted emission testing does not apply to this product. The device is powered from a 3 volt lithium battery. * Please refer to FORMULAS and SAMPLE CALCULATIONS for Duty Cycle correction factor calculation Changes made to achieve compliance 1. The resistor, R1 was changed to 1.2Kohm to achieve desired field strength of the fundamental. AHD EMC Lab, 92723 M152, Dowagiac, MI 49047, (269) 424-7014 0500814B.doc EXHIBIT E: Page 6 of 16

Test report #0500814B FCC 15.231 for 1800-TIM-TW4 FCC ID: IVS1800TIMTW Tested Sep 21, 2005 Standards Applied to Test: ANSI C63.4 - 2001 CFR47 FCC Part 2;, Part 15, SubPart C, 15.231b Intentional Radiator; SubPart B, Digital Device, AHD test procedures TP0101-01, TP0102-01 Equipment Configuration For the testing, the placement of the EUT and the support equipment was selected to -- 1) be a representation of the installed configuration, and 2) comply with the minimum system configuration of ANSI C63.4. Test Methodology: Radiated testing, performed at a 3 meter open field test site, was completed according to the procedures in FCC 15, SubPart C with supporting instructions from ANSI C63.4 For the testing, the EUT was placed at the center of the table 80cm above the ground plane pursuant to ANSI C63.4 for stand-alone equipment. The turntable was rotated 360 degrees and the receiving antenna height varied from 1 to 4 meters to search out the highest emissions. The setup pictures in this report indicate the configuration of testing for this product. The internal lithium battery was replaced periodically throughout the testing to ensure that the greatest available battery power was available to the transmitter. The line conducted emission testing was not performed on this product. In its final configuration the product is powered from an internal lithium battery only. At frequencies up to 1000MHz a BiconiLog broadband antenna was used for measurements. At frequencies above 1000MHz a double-ridge Horn broadband antenna was used for measurements. During the transmitter evaluation the EUT was transmitting continuously. The turntable was rotated 360 degrees and the receiving antenna height varied from 1 to 4 meters to search out the highest emissions. The principle settings of the EMI Receiver for radiated testing include: IF Bandwidth: 120KHz for frequencies less than 1GHz. 1 MHz for frequencies greater than 1GHz. Detector Function: Peak Mode The Average levels were determined mathematically based upon the duty cycle of the pulsed modulation of the transmitted signal.

Test report #0500814B FCC 15.231 for 1800-TIM-TW4 FCC ID: IVS1800TIMTW Tested Sep 21, 2005 The final measurements were made with the EUT placed in one of two positions (designated as side, and end). Measurements were recorded in each of these two positions and with the measuring antenna in vertical and horizontal positions. The unit was evaluated up to the tenth harmonic of the transmit fundamental, and up to 5000MHz for other spurious signals. The nominal operating frequency of the transmitter is 433.92 MHz. The frequency determining element is quartz crystal Y1 which operates at 13.56 MHz. The crystal frequency is multiplied by a factor of 32 using a phase-locked loop to produce the output frequency. Whenever a remote switch input is activated, encoder IC U1 produces Manchester encoded data pulses. Data packets consist of a preamble, a header, a start bit, 69 data bits, and a stop bit. The minimum time between pulse transitions is nominally 200 us. LED D1 flashes to indicate transmitter operation and battery status. The transmitter section consists of IC U2. Input pulses on the DATA pin (U2-6) activate the transmitter and amplitude modulate its output using On-Off Keying (OOK). The transmitter IC powers down approximately 5 ms after the last pulse transition. Transmitter output PAOUT (U2-4) is biased through inductor L1 and resistor R1 which are bypassed by C5, C6, and C7. R1 limits the available drive current to the transmitter output stage, thereby providing a means to control the output power. The RF output is lowpass filtered by a pi filter consisting of C8, L2, and C9. The circuit board loop antenna is matched to the transmitter output via capacitors C9 and C10. The transmitter is powered by two 3V lithium coin cells connected in parallel. Since the transmitter is classified as an intermittent control signal, for the transmitter fundamental and harmonics, where peak detection is permitted, a 33.9% duty cycle is applicable. 33.9% duty cycle is equivalent to a 9.4dB duty cycle factor [ 20*Log(.339) = -9.4dB ]. The duty cycle factor was not applied to the measurements of the field strength of emissions above 1000MHz when comparing those levels to the permissible limits. The system was placed at the center of the table 80cm above the ground plane pursuant to ANSI C63.4 for stand-alone equipment.

Test report #0500814B FCC 15.231 for 1800-TIM-TW4 FCC ID: IVS1800TIMTW Tested Sep 21, 2005 FORMULAS AND SAMPLE CALCULATIONS: THE HP8546A EMI Receiver has stored in memory the antenna and coax correction factors used in this test. The resultant Field Strength (FS) in dBuV/m presented by the HP8546A is the summation in decibels (dB) of the Received Level (RF), the Antenna Correction Factor (AF), and the Cable Loss Factor (CF). Formula 1: FS(dBuV/m) = RF(dBuV) + AF(dB/m) +CF(dB) With the EUT in transmitting mode the resultant Field Strength measurement is recorded using the peak hold detector of the HP8546A. Where it was necessary to move the EUT to 1 meter distance to take measurements a ‘dB’ factor which adjusts for this distance variance is used before comparing the emission level to the FCC limits. This factor is determined by the following formula. Formula 2: The FCC field strength limit of the fundamental is [125*f(MHz)/3 – 21250/3]uV/m at a measurement distance of 3 meters. This number is equivalent to 80.82dBuV/m. Since f = 433.92MHz, the FCC field strength limit of fundamental is: [125*433.92/3 – 21250/3]uV/m = [18080 – 7083]uV/m = 10996.67uV/m 20*Log(10996.67uV/m)=80.82dBuV/m Formula 3: Duty Cycle Calculations: Each bit transmitted has a 52% Duty cycle. Over a 100ms, the transmission total packet duration (Preamble + header + start bit + data + stop bit for two complete packets) is 65.2ms Picture showing 100ms transmission after button press Maximum Duty cycle averaged over any 100ms interval = (52%*65.2ms)/100ms Therefore, the maximum averaged duty cycle = 33.9% Formula 4: Correction factor for Maximum averaged duty cycle Correction factor = 20*log(0.339) = 9.4dB AHD EMC Lab, 92723 M152, Dowagiac, MI 49047, (269) 424-7014 0500814B.doc EXHIBIT E: Page 12 of 16
