Type of Equipment : Tire Pressure Monitoring System (Receiver) Model No. : 23AAK Serial No. : Refer to Section 4, Clause 4.2 Receipt Date of Sample : April 26, 2012 Country of Mass-production : Japan Condition of EUT : Engineering prototype (Not for Sale: This sample is not mass-produced items.) Modification of EUT : No Modification by the test lab 2.2 Product Description Model No: 23AAK (referred to as the EUT in this report) is the Tire Pressure Monitoring System (Receiver). 23AAK has 6 variations. For details of variations, see “Technical document for Type Approval”. Feature of EUT : 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. Frequency of Operation : 314.98MHz Oscillator Frequency : 21.948717MHz (Crystal) Type of modulation : FSK (F1D) Type of receiver : Super-heterodyne Intermediate frequency : 10.7MHz Operating voltage (inner) : DC 12.0V Antenna type : Internal Antenna (Inverse F Antenna / Inverse L Antenna) FCC15.111(b) The receiving antenna (of this EUT) is installed inside the EUT and cannot be removed (permanently attached). Therefore, Radiated emission test was performed. Test report No. : 32IE0311-HO-01-B-R1 Page : 4 of 14 Issued date : May 29, 2012 Revosed date : May 30, 2012 FCC ID : HYQ23AAK UL Japan, Inc.
