FCC ID#: OBH 22250 Applicant: LESTER ELECTRICAL Applicant’s Address: 625 “A” Street. Lincoln Nebraska 68522-1794 Model: Temperature Sender Module #22250 Serial Number: N/A Project Number: 01386-10 Test Dates: March 30, 2001 I, Jeffrey A. Lenk, for Professional Testing (EMI), Inc., being familiar with the FCC rules and test procedures have reviewed the test setup, measured data and this report. I believe them to be true and accurate. The LESTER ELECTRICAL Temperature Sender Module #22250 was tested to and found to be in compliance with FCC Part 15 Subpart C for an Intentional Radiator. The highest emissions generated by the above equipment are listed below: Frequency (MHz) Level (dBμV/m) Limit (dBμV/m) Margin (dB) Fundamental 916.631 78.3 94 -15.7 Occupied Bandwidth 105 KHz measured at –26 dBC. Fundamental frequency is 916.631 MHz. In the 902– 928 MHz Band. ______________________________ Jeffrey A. Lenk President Certificate of Compliance 1.0 EUT Description The Equipment Under Test (EUT) is the LESTER ELECTRICAL Temperature Sender Module #22250. The Temperature Sender Module #22250 is a 3 by 4 ¾ inch potted module with no external connections. It is powered from a 1-ampere hour 3-volt lithium battery attached to the backside of the printed circuit. The temperature sender senses the temperature of what it is attached to and transmits an ID number and temperature reading (less than twenty bytes of data) once every 5 to 15minutes. The transmission takes approximately 250 milliseconds to accomplish. It transmits a pulsed signal at nominally 916.5 MHz. The EUT operates at 916.56 MHz and is designed for compliance with 47 CFR 15.249 of the FCC rules. Specific test requirements for this device include the following: 47 CFR 15.249 Fundamental Transmit Power 47 CFR 15.249 & 15.205 Spurious Radiated Power 47 CFR 15.249 & 2.1049&15.215 Occupied Bandwidth (ANSI C63.4 used as Procedural Reference) 47 CFR 15.203 Antenna Requirement The system tested consisted of the following: Manufacturer & Model Serial # FCC ID # Description LESTER ELECTRICAL, Temperature Sender Module #22250 001 #22250 Temperature Sender Module 1.1 EUT Operation The Temperature Sender Module #22250 was placed into operation which caused continuous transmitting. 2.0 Electromagnetic Emissions Testing Professional Testing (EMI), Inc. (PTI), follows the guidelines of NIST for all uncertainty calculations, estimates and expressions thereof for EMC testing. Radiated emission measurements were made of the Fundamental and Spurious Emission levels for the Temperature Sender Module #22250. Measurements of the occupied bandwidth were also made for the equipment. Measurements of the maximum emission levels for the fundamental and the spurious/harmonic emissions of the Temperature Sender Module #22250 were made at the Professional Testing "Open Field" Site #3, located in Round Rock, Texas to determine the radio noise radiated from the EUT. A “Description of Measurement Facilities” has been submitted to the FCC an…
