Page 1 of 1 FCC ID: OJS990001 & OJS990002 Product Description Keyless Entry System Using Radio Frequency Transmit and Receiver Electronics MET has developed a keyless entry system using a radio frequency transmitter and receiver. The transmitter will transmit a 418 MHz OOK On-Off keying) signal to the receiver. The signal transmitted a digital encrypted using a Keeloq TM rolling code algorithm at a 400 microsecond per bit baud rate, 61 bits per code. The receiver will receive the 418 MHz signal and decode the digital signal using the same Keeloq algorithm. The 3 possible signals that will be decoded by the receiver are unlock, lock, and enable/disable alarm. The microcomputer electronics at the receiver will proceed to perform the requested access control functions. The expected distance from the transmitter to the receiver is a 30-foot range.

The EUT is manufactured by Micro Enhanced Technology, Inc. The EUT consists of four momentary push button switches, an RF oscillator (418 MHz SAW based), a single 3V lithium coin cell battery, and a custom IC. In normal use nothing occurs until one of the four buttons is pressed. The RF oscillator is a simple ON-OFF Keyed stage. Once the transmission is complete the custom IC goes into a standby mode and remains inactive until the next button is pressed. 1.2 Related Submittals The associated receiver is currently being submitted pursuant to the Certification equipment authorization as FCC ID: OJS990001. 1.3 Tested System Details The identification for the EUT is as follows. Model Number Serial NumberFCC ID Manufacturer & Description Cable Descriptions M/N: 990002 (EUT)OJS990002Micro Enhanced Technology Inc. 418 MHz Transmitter No cables can be connected to the EUT 1.4 Test Methodology The test procedures used are in accordance with the ANSI document C63.4-1992, (July 17, 1992) "Methods of Measurement of Radio Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz". The specific procedures are described herein. Radiated testing was performed at an antenna to EUT distance of 3 meters. The antenna was raised and lowered from 1 to 4 meters. 1.5 Test Facility The open area test site used to collect the radiated data is located on 8625 Helmar Road in Newark, Illinois. The open field test site has a metal ground screen. Details of the site characteristics are on file with the FCC. Conducted emission measurements and preliminary radiated emission scans were performed in shielded enclosure “B” at Radiometrics' Romeoville, Illinois EMI test lab. These sites have been fully described in a report and accepted by the FCC in a letter dated October 1, 1996 (31040/SIT 1300F2).
