Operational Description (FCCID:NEX-94102-49) 1) IC1 and the associated circuit act as AF-Modulator. 2) Q1 and the associated circuit act as a RF-transmitter. Q2 together with 40.860 MHz crystal oscillator drive the base of Q1, signal from Q2 and the modulation provided by IC1 are then summed into Q1. 3) The matching network at output of Q1 is to limit the harmonic content and provide the proper coupling to antenna output.

The EUT has two control rods for commanding the forward, backward, left and right movement of the associated receiver. Due to declaration from the manufacturer, it is deemed that that the transmitter of 9412 and 9417 are same in circuit design and PCB layout as the transmitter of 9410, they only differ in the cosmetic design. Hence, all testing was conducted on the representative model: 9410. FCCID: NEX-94102-49 Model Product description 9410 Pro Racer Subaru 9412 Pro Racer Citroen Circuit Description IC1 and the associated circuit act as AF-Modulator. Q1 and the associated circuit act as a RF- transmitter. Q2 together with 49.860 MHz crystal oscillator drives the base of Q1, signal from Q2 and the modulation provided by IC1 are then summed into Q1. The matching network at output of Q1 is to limit the harmonic content and provide the proper coupling to antenna output. Ratings and System Details Transmitter Frequency range : 49.860 MHz Number of channels : 1 Type of antenna : Integral antenna Power supply : Battery operated 9V Ports : none Protection Class : III www.tuv.com Test Report No.: 14006776 001 Date: 11.08.2004 Page 7 of 13 Independent Operation Modes The basic operation modes are: - Remote Control: On and Off 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 a single application for certification of the transmitter. www.tuv.com Test Report No.: 14006776 001 Date: 11.08.2004 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 devic…
