By pressing a button on the keypad a signal is sent to the microprocessor. That signal in turn is converted into a number that is compiled with an address code, that is pre-selected and set by jumpers. This compiled number is the sent serially at 2.4KB/s to TX module. This signal is then processed by the tx module and radiated at 315.0 Mhz at a level not to exceed FCC standards. The tx module has an onboard 9.84 Mhz crystal oscillator that is used to generate the RF signal. The radiated signal is modulated at the 2.4KB/s rate in a Frequency Shift Modulation manor. The unit is battery powered and is controlled by an on/off switch. The battery voltage is obtained from 4 AA batteries that are converted to 5 VDC by a boost/buck DC-DC converter. This converter operates at 19Khz (approx.) and should not radiate any detrimental signals. Low battery conditions are indicated by a LED mounted in the case of the transmitter. The indicator will flash red when a button is pushed on the transmitter keypad. Under normal operation the LED will be a constant green indication. Applied Electronics Company

The test report is based on testing performed by Compatible Electronics personnel according to the measurement procedures described in the test specifications given below and in the "Test Procedures" section of this report. The measurement data and conclusions appearing herein relate only to the sample tested and this report may not be reproduced without the written permission of Compatible Electronics, unless done so in full. This report must not be used to claim product endorsement by NVLAP, NIST or any other agency of the U.S. Government. Device Tested: Hand Held Transmitter Model: MP4JSB-TX S/N: B06s4-161 Product Description: See Expository Statement Modifications: The EUT was not modified during the testing. Manufacturer: Applied Electronics Company 3132 Brown Street Boise, Idaho 83714 Test Date: February 12, 2008 Test Specifications : EMI requirements CFR Title 47, Part 15 Subpart B; and Subpart C, Sections 15.205, 15.209 and 15.231 Test Procedure: ANSI C63.4 Test Deviations: The test procedure was not deviated from during the testing. SUMMARY OF TEST RESULTS TEST DESCRIPTION RESULTS 1 Conducted RF Emissions, 150 kHz - 30 MHz This test was not performed because the EUT operates on battery power only and cannot be plugged into the AC public mains. 2 Radiated RF Emissions, 10 kHz – 3.15 GHz Complies with the Class B limits of CFR Title 47, Part 15, Subpart B; and Subpart C, sections 15.205, 15.209, and 15.231.
