Type of Equipment : Remote Keyless Entry Model No. : TWB1U751 Serial No. : Automatically deactivate: #3, Other test: #2 Rating : DC3V (Battery) Country of Manufacture : Japan Receipt Date of Sample : March 15, 2007 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: TWB1U751 (referred to as the EUT in this report) is a Remote Keyless Entry, which is carried by the owner of the vehicle. It performs transmission through RF antenna to tuner, vehicle performs actions according to the signal. (Door lock or unlock, Panic) Equipment type : Transmitter Frequency of operation : 315MHz Clock frequency : CPU: 4MHz Type of modulation : ASK Antenna type : Internal/PCB Pattern (Loop) Antenna connector type : None ITU code : A1D Operation temperature range : -10 to +60 deg.C. *FCC Part15.31 (e) This test was performed with the new battery (DC 3V); therefore, this EUT complies with the requirement. *FCC Part15.203 It is impossible for end users to replace the antenna, because the antenna is mounted inside of the EUT. Therefore, the equipment complies with the requirement. FCC ID : CWTWB1U751 Test report No. : 27HE0166-YK-A Page : 4 of 20 Issued date : March 28, 2007 UL Apex Co., Ltd.
