After our construction checking and declaration by the manufacturer, it is deemed that the transmitter of U-601,U-632AW, U-632BW, U-635W, U-639F and U-639W are identical in PCB layout and function, they only differ in cosmetic design. Hence the representative transmitter for model:U- 639F was chosen to conduct all testing. FCCID: SSC-DBU600WST Model Product description U-601,U-632AW, U-632BW, U-635W, U-639F U-639W Wireless Door Chime ( Transmitter ) Circuit Description U1 and the associated circuit act as address Code Encode. Q2 and the associated circuit act as a 433.920MHz Oscillator. Ask Modulator to limit the harmonic content and provide to antenna output. Ratings and System Details Transmitter Frequency range : 433.920 MHz Number of channels : 1 Type of antenna : Integral antenna Power supply : Battery operated 12.0V, Type:23AE Ports : none Protection Class : III www.tuv.com Test Report No.: 14008204 001 Date: 15.12.2004 Page 7 of 13 Independent Operation Modes The basic operation modes are: - Remote Control : It has a push to operate switch and is under manual control at all transmission time. It will cease transmission within 5 seconds after activation. For further information refer to User Manual Submitted Documents The submitted documents are listed as follow: - Circuit diagram - Block diagram - User manual - Label artwork Related Submittal(s) Grants This is single application for certification of the transmitter. www.tuv.com Test Report No.: 14008204 001 Date: 15.12.2004 Page 8 of 13 Test Set-up and Operation Mode Principle of Configuration Selection Emission: The equipment under test (EUT) was configured to measure its highest possible radiation level. The test modes were adapted accordingly in reference to the instructions for use. Test Operation and Test Software Test operation should refer to test methodology. - There was no special software to exercise the device. Special Accessories and Auxiliary Equipment The prod…
