FCC ID: KJ8HHT-372ESW GENERAL INFORMATION Product Description The Equipment Under Test (EUT) is a Wayne-Dalton Corp., Model 3BTM-E372. The EUT is a 3-button hand transmitter operating at 372.5 MHz using OOK modulation for use with Wayne-Dalton Corp. garage door openers. The EUT incorporates an internal antenna only. The antenna is etched directly on the PCB board. It has an irregular shape which resembles the letter “G”. The upper horizontal track measures 0.325” x 0.040”, the vertical track measures 1.185” x 0.040”, and the lower horizontal track measures 0.515” x 0.040”, and the last vertical track 0.0555” x 0.040”. Related Submittal(s)/Grant(s) The EUT will be used with DoC approved receivers.

FCC ID: KJ8HHT-372ESW SECTION 2 TESTS AND MEASUREMENTS FCC ID: KJ8HHT-372ESW 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 a hand held device, it was placed into a continuous mode of transmit and rotated about all 3 axis to obtain worse case results. 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 3 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 48.750 msec as shown in Figure 3. FCC ID: KJ8HHT-372ESW FIGURE 3 Periodic Operation 15.231(a)(c1) FCC ID: KJ8HHT-372ESW Field Strength of Fundamental Emission (47 CFR 15.231b) Measurements were made using a peak detector. Field strength of the peak fundamental emission is shown in Table 3 and Figure 4. Duty Cycle Correction During 100 msec: Each function key sends a different series of characters, but each packet period (93.750 msec) never exceeds a series of *66 long (500.0 μs) and short (350.0 μs) pulses. Assuming any combination of short or long pulses may be obtained for the data due to en…
