Type of Equipment : TPMS/KEYLESS RECEIVER Model No. : TWD1U848 Serial No. : Refer to Section 4, Clause 4.2 Receipt Date of Sample : June 8, 2013 Country of Mass-production : Estados Unidos Mexicanos Condition of EUT : Production 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: TWD1U848 (referred to as the EUT in this report) is the TPMS/KEYLESS RECEIVER. General Specification Feature of EUT : This TPMS TUNER CONT receives and detects RF signal from remote control, and performs locking or unlocking of a door. It also receives RF signal from TPMS censor, warns trouble of air pressure. Clock frequency in the system : 35.55MHz (Oscillator circuit) Radio Specification Frequency of operation : 315MHz Oscillator Frequency : 29.5098MHz Local Oscillator Frequency : 314.77MHz Intermediate Frequency : 230kHz Type of modulation : ASK Operating voltage : DC 9 to 16V Antenna Type : Built-in Antenna Operating Temperature : -30 to +80 deg. C 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.
