Appendix A contains test photos, Appendix B contains original test data and Appendix C contains sample calculations. The data contained in this report reflects only the items tested in the configurations and mode of operations described. An attempt has been made to arrange the EUT, with the equipment provided, into a test configuration which maximizes the observed emissions of the EUT while simulating, as close as practical, a typical end-use installation. The photos and data provided in this report document that configuration.

FCC ID: JM7-IGWT-662002 1.0 GENERAL PRODUCT DESCRIPTION The Equipment Under Test (EUT) is an infant security module. The module is warn by the infant and if the module is removed or if the infant is passed through an area with doorway modules active (transmitting 132 kHz signal), the TAG then transmits a 418 MHz signal to a central receiving module which is in turn connected to the graphical display system or Multiplexer. 1.0.1 Equipment Mobility: Floor Standing. See Appendix A for configuration photos. 1.0.2 Test Voltage and Frequency: Voltage (V) Frequency (Hz) 1.5 DC 1.1 MODEL DIFFERENCES Any other model(s) represented by the models tested in this investigation will be documented by the manufacturer. 1.2 ENVIRONMENTAL CONDITIONS IN TEST LAB Temperature: 20-25 °C Relative Humidity: 30-60% RH Atmospheric Pressure: 860-1060 mbar 1.3 CALIBRATION OF EQUIPMENT USED FOR MEASUREMENT All test equipment and test accessories are calibrated on a regular basis. The maximum time between calibrations is one year or what is recommended by the manufacturer, whichever is less. All test equipment calibrations are traceable to the National Institute of Standards and Technology (NIST), therefore, all test data recorded in this report is traceable to NIST.

The device does not operate in the standby mode until it receives a 132 kHz signal from a doorway module or the strap has been removed from the infant. Measurements were maximized with the device situated in the 3 orthogonal axes. Testing was conducted with a new battery. 1.6 DEVICE MODIFICATIONS The following modifications were necessary for compliance: None File: MC1670 Project: 02NK45212 Page 4 of 10 UL International EMC Services www.ul.com/emc (800) USE UL EMC

FCC ID: JM7-IGWT-662002 APPENDIX C Sample Calculations of Field Strengths Basic Equation: The field strength is calculated by adding the Meter Reading, Cable Set Gain/Loss and Transducer (Antenna or LISN) Factor. The basic equation is as follows: FS = MR + GL + TF Where: FS = Calculated Field Strength in dB(uV)/meter MR = Meter Reading of receiver amplitude in dB(uV) GL = Gain/Loss factor of cable set in dB A negative Gain/Loss indicates signal amplification (gain) A positive Gain/Loss indicates signal attenuation (loss) TF = Transducer Factor of antenna or LISN in dB Sample Calculation: The measured receiver amplitude is 52.7 dB(uV). The gain/loss factor is –30.2 dB (indicating a preamplifier is included in the cable set). The transducer factor (antenna factor) is 6.6 dB. These factors are added (52.7 + (-30.2) + 6.6) resulting in a calculated field strength of 29.1 dB(uV)/meter.

FCC ID: JM7-IGWT-662002 Sample Calculations of Limit Basic Equation: The limit is calculated by using the information in table 15.209 for frequency (MHz), field strength (uV/m) and measurement distance (meters). The basic equation for converting uV/m to dBuV/m is as follows: 20 Log (uV/m) = dBuV/m Where: uV/m = micro volts per meter dBuV/m = decibel micro volts per meter Sample Calculation: The field strength per section 15.209 at 30 MHz (3 m measurement distance) is 100 uV/m. 20 Log (100 uV/m) = 40 dBuV/m File MC3486 Project 02NK Page C2 of C2 UL International EMC Services www.ul.com/emc (800) USE UL EMC
