Type of Equipment : TPMS/RKE Receiver Model No. : TWD1G776 Serial No. : Refer to Section 4, Clause 4.2 Receipt Date of Sample : December 24, 2014 Country of Mass-production : Japan 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: TWD1G776 (referred to as the EUT in this report) is the TPMS/RKE Receiver. Feature of EUT : This TPMS/RKE Receiver receives and detects RF signal from keyless transmitter, and performs locking or unlocking of a door. It also receives RF signal from TPMS censor, warns trouble of air pressure. General Specification Clock frequencies in the system : 17.77MHz Radio Specification Frequency of operation : 433.92MHz Type of modulation : FSK Antenna Type : Built-in transformation whip antenna Method of Frequency Generation : Crystal, PLL Local frequency : 433.6896MHz IF frequency : 230kHz Operating voltage (inner) : DC 9.0V to 16.0V Operating Temperature : -30 deg. C 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.
