Applicant: Inovonics Wireless Corp. FCC ID: HCQ3B6UXFH24M Correspondence Ref. Number: 26726 731 Confirmation Number: EA166940 Re: “Please explain how this device complies with the modular transmitter requirements for a Part 15 device, as described in document DA 00-1407.” Compliance with Public Notice DA 00-1407 Public Notice DA 00-1407 contains guidelines and requirements for obtaining modular transmitter approval. The transmitter in question is a self-contained device having its own reference oscillator, permanently attached antenna, and RF shielding. The only external connection to the module is the switch contact input. 1. This module contains shielding to mitigate RFI and does not rely upon external shielding from the device to which it is attached. 2. The switch contact input is buffered by the micro-controller within the module. 3. This module is designed to operate from a 3V primary cell within the module. An internal voltage regulator provides a stable power supply to the VCO and PA driver stages. 4. The antenna is permanently affixed to the module, per 15.204. The Internal Photo inserted from the initial report has been updated to designate the antenna structure. 5. The module was tested as a stand-alone device. 6. The module is labeled with the FCC ID. In addition, the products in which it is integrated are labeled with the FCC ID. 7. The module complies with Part 15.247 of the FCC rules. No combination of input stimuli exist that could cause the module to operate in a manner that is not consistent with the rules. 8. The module complies with MPE requirements, as outlined in the MPE exhibit.

CONFIDENTIAL FCC ID: HCQ3B5UXFH24M FA-250M 3/17/2004 FA-250M Transmitter Certification Testing – Additional Notes Duty Cycle: The duty cycle is calculated over a 100 mSec averaging window as specified in the rules. The message packet contains a total of 213 pulses each 20 uSec in duration, for a total transmitter on time of 4.26 mSec with represents a worst- case duty cycle of 4.26%. The duty cycle correction used is the maximum of 10%. MPE: Calculation for compliance with MPE requirements (Section 2.1091) using a worst case of 0.25 Watt, unity antenna gain, and the f/300 (mW/cm 2 ) limit for general applications. This device is used in fixed locations and is not carried or worn by the end user. The key factor is duty cycle. Under normal conditions, a 12-packet message is sent a maximum of once every 15 minutes. Worst case, a 12-packet message is sent, once per minute, or 72 packets in a 6-minute period. Total On time per packet = 4.26 mSec (for maximum packet length) Duty Cycle = (4.26 x 72) mSec/(6x60x1000) mSec = 0.0852% EIRP = (0.25W)(0.000852) = 213 microwatt. Using a distance of 20 cm: 213 microwatt / (4 pi 20 2 ) = 42.38 nW/cm 2 Dwell Time: The Dwell Time is the length of one packet. The worst-case dwell time for an extended length packet is 40.1 mSec. The standard packet is about 30 mSec duration. A worst-case transmission rate, corresponding to a repeated change of state transmissions would result in a maximum of 12 packets in any 10-second period with each packet on a different frequency. The maximum dwell time is thus the dwell time of an extended packet or 40.1 ms. Modular Approval: Public Notice DA 00-1407 contains guidelines and requirements for obtaining modular transmitter approval: A. The FA-250M transmitter module is a self-contained device, powered by an internal single cell, 2/3 A size LiMnO2 primary cell (nominally 3 Volts). An internal voltage regulator provides a stable power supply to the VCO and PA driver stages. B. The module has its own reference oscillator, permanently attached internal antenna per 15.204, and RF shielding over the transmitter portion of the module. C. An external switch or data input activates the module, to signal a change of state. This input is buffered by the internal microcontroller. D. The module complies with all applicable FCC rules including 15.247. E. The module was tested as a stand-alone device. CONFIDENTIAL FCC ID: HCQ3B5UXFH24M FA-250M 3/17/2004 Measurements performed at Inovonics Wireless Corp. lab Equipment used: HP-8594E Spectrum Analyzer Conducted Power Output: The antenna was removed and a coax was temporarily connected to allow for direct measurement of power using the spectrum analyzer. The power output was measured at +21 dBm was measured into 50 ohms. Spectrum Plots: The following two spectrum plots were made using a test antenna closely coupled to the test unit. Spectrum Plot 1 shows two adjacent channels with modulation. Compliance with section 15.247(a)(1) is demonstrated with a test sample configured with firmware allowing two adjacent channels to be captured. Plot 1 also shows the 20 dB bandwidth of a single channel of 300 kHz, to demonstrate compliance with 15.247(a)(1)(i).

This is a stored display of many sequential transmissions to show the overall band occupied by the transmitter.
