American Telecommunications Certification Body Inc. 6731 Whittier Ave, McLean, VA 22101 July 19, 2002 RE: FCC ID: KJ8WST-372BSW Attention: Timothy Johnson I have a few comments on this Application. 1 HP has stated that when the video bandwidth is less than one tenth the Resolution bandwidth the analyzer is averaging. Please note, the video bandwidth shown on page 19 of the report is less than one tenth the resolution bandwidth ( actually it is less than one hundredth the RBW). This means that you are in the process of averaging the signal. While a true average does not take place until the video bandwidth is at 1 Hz, none the less, the analyzer is averaging the signal in the plot. This means that you are improperly reducing an already partially averaged reading by the pulse width modulation factor. This is born out by applying the correction factors and PWDC to the true peak reading shown in the OBW plot on page 33 (assuming this OBW plot was taken at 3 meters). The peak reading shown on page 17 of the report is incorrect and according to the above concern with the OBW plot the device appears to fail. Please retest the device properly applying the pulse width averaging technique to the true peak reading of the signal as specified in ANSI C63.4 section 13.1.4.2. Please verify that the true peak reading is in compliance with the 20dB over averaged (pulse width averaged) reading. 2 The plots on page 29 and 30 have the same problem as in item 1. Please remember that the Pulse Width Duty Cycle averaging is done on and absolute Peak, not a partially averaged reading. Please proved plots showing the video bandwidths equal to or greater than the Resolution Bandwidth, thus placing the analyzer in a peak reading mode and not an averaging mode. 3 Please note that the comment in table 7 may be incorrect. It states that the digital circuitry is not used except to turn the transmitter on. However, the digital circuitry also provides the digital modulation fed to the base of Q1 at the same time it turns Q1 on. This means that the digital pulse stream from the processor is active the entire time the transmitter is active and is an integral part of the transmission itself. Thus, measurements from 30 MHz to 1000MHz appear proper. Also please note that digital device emissions measurements fall under 15.109 while transmitter emissions fall under 15.209. Please show that the device is compliant to 15.209 requirements. Alternately, please explain how the digital circuitry is disabled during transmission. 4 The manual is for a model KEP2-0000 wireless keyless entry system. The model in question is 5BWS-A372 garage door opener. The manual then appears to be for the wrong device. Please provide a manual for the device tested.

FCC ID: KJ8WST-372BSW SECTION 2 TESTS AND MEASUREMENTS FCC ID: KJ8WST-372BSW TESTS AND MEASUREMENTS Configuration of Tested System The sample was tested per ANSI C63.4, Methods of Measurement from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz (1992). Conducted and radiated emissions data were taken with the test receiver or spectrum analyzer's resolution bandwidth adjusted to 9 kHz and 120 kHz, respectively. All measurements are peak unless stated otherwise. The video filter associated with the spectrum analyzer was off throughout the evaluation process. Interconnecting cables were manipulated as necessary to maximize emissions. A block diagram of the tested system is shown in Figure 1. Test configuration photographs for spurious and fundamental emissions are shown in Figure 2. Since the EUT is wall mounted, it was placed into a continuous mode of transmit and positioned in an upright position. Test Facility Testing was performed at US Tech's measurement facility at 3505 Francis Circle, Alpharetta, GA. This site has been fully described and submitted to the FCC, and accepted in their letter marked 31040/SIT. Additionally this site has also been fully described and submitted to Industry Canada (IC), and has been approved under file number IC2982. Modifications No modifications were made to bring the EUT into compliance with FCC Part 15, Class B Requirements. Test Equipment Table 2 describes test equipment used to evaluate this product.

The transmitter is a 5 button transmitter. The EUT continues to transmit while each button is being pressed. The EUT ceases transmission almost immediately upon being released and appears to finish the current packet being transmitted. Therefore the longest period of time the transmitter should take to deactivate is a packet length, or 45.000 msec as shown in Figure 3.
