Type of Equipment : Remote Keyless Entry System and TPMS (Receiver) Model No. : 23AAC Serial No. : Refer to Section 4, Clause 4.2 Receipt Date of Sample : August 6, 2010 Country of Mass-production : Japan and United States of America Condition of EUT : Engineering prototype (Not for Sale: This sample is equivalent to mass-produced items.) Modification of EUT : No Modification by the test lab 2.2 Product Description Model No: 23AAC (referred to as the EUT in this report) is Remote Keyless Entry System and TPMS (Receiver). 23AAC has 12 variations. For details of variations, see “Theory of Operation”. Hereinafter, Remote Keyless Entry System is called “RKES” in this report. Feature of EUT: <RKES mode> RKE system is mainly used for locking or unlocking the doors of the vehicle. The transmitter sends a radio wave signal while the button is pushed. The receiver becomes active in response to the signal from the transmitter. <TPMS mode> Tire Pressure Monitoring System is used for monitoring and indicating information of air pressure in vehicle’s tires. Transmitter sends receiver the data that are information of air pressure in vehicle’s tire. The data also include temperature, battery voltage and identity code of transmitter. The receiver judges the data. If the data of air pressure and others are not normal condition, the receiver sends signal to a warning lamp. Then, the warning lamp warns drivers. AUTOMATIC LOCATION System is used for showing air pressure in vehicle’s each tire. The multiple antennas fitted to the vehicle transmit a low-frequency wave signal. The system automatically detects the wheel position involved in a pressure reading, even after tire rotation. Type of receiving system : Super-heterodyne Frequency of Operation : RKES (CH1): 314.35MHz RKES (CH2): 312.10MHz TPMS: 314.98MHz Oscillator Frequency : 25.2MHz (Crystal) Type of Modulation : RKES: FSK (F1D) TPMS: FSK (F1D) Power Supply : DC12.0V Antenna Type : Internal antenna (Inverse F antenna / Inverse L antenna) Test report No. : 30KE0045-HO-01-A Page : 4 of 33 Issued date : September 6, 2010 FCC ID : HYQ23AAC UL Japan, Inc.
