Response for Request for information (request sent 12/28/01) for Re: FCC ID PWZR142T Applicant:All-Line, Inc. Correspondence Reference Number: 3362 731 Confirmation Number: TC712830 1.) To what maximum frequency was the EUT tested? Conflicting information is included in the application. For transmitter spurious emissions, the device was tested to 3.5 GHz. 2) The modification list is not legible. In the future make sure that all exhibits submitted are clear. This is noted. The original was unclear due to the fact that the page had been faxed multiple times (the project was originally completed about 4 years ago). Now almost all clients use email which solves this problem. However, for reference on this application, here is text of the modifications: 1. Changed R6 from 47 kOhm to 87 kOhm 2. Changed C6 from 5pF to 100pF 3. Added 20 Ohm between C4 and Q2 base 4. Added 10pF between Q2 emitter and collector 5. Used Tokin STB04105 Choke instead of IND1 inductor

FCC ID: PWZR142T GENERAL INFORMATION Product Description The Equipment Under Test (EUT) is a All-Line, Inc., 314.0 MHz Wireless Door Chime, Model R14-2T. The EUT is part of a system including a door chime receiver. This product was originally tested and approved in 1998. The EUT is being identified under a different trade name and model number, therefore the manufacturer has requested that the unit be re-certified. Related Submittal(s)/Grant(s) The EUT will be used with a DoC Approved receiver.

FCC ID: PWZR142T SECTION 2 TESTS AND MEASUREMENTS FCC ID: PWZR142T 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 as described to the FCC and acknowledged in their letter marked 31040/SIT/USTECH. Test Equipment Table 2 describes test equipment used to evaluate this product.

The transmitter is a 1 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 15 ms as shown in Figure 3. FCC ID: PWZR142T FIGURE 3 Periodic Operation 15.231(a)(c1) FCC ID: PWZR142T 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 (29.125 msec) never exceeds a series of 13 long (800 ìs) and short (400 ìs) pulses. Assuming any combination of short or long pulses may be obtained due to encoding the worse case transmit duty cycle would be considered 13 x 800 ìs per 29.125 msec = 36% duty cycle. Figures 5a through 5c show the characteristics of the pulse train for one of these functions. Duty Cycle Correction = 20 log(0.36) = -8.8dB Field strength of the average fundamental emission is shown in Table 4. FCC ID: PWZR142T TABLE 3 FIELD STRENGTH OF FUNDAMENTAL EMISSION Test Date:Marc…
