U6QSHTDRCEW0703Remote Control Transmitter

TD 3000 Instruction: Q Operating Frequency: 315MHz Q Using code: 2 codes (symbol A or B, standard for forward and reverse direction of the electrical winch) Q Battery Type: 12V alkaline battery Q FCC notice: Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. FCC statement: This device complies with Part 15 of the FCC Rules. Operations is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. Q Operation Instruction: Þ Put a 12V alkaline battery into the battery cover (battery polar +/-) Þ Press A for the winch running forward, Press B for the winch running reverse. Þ The remote control distance will be about 5m. Warning: After the winch is running, it may generate disturbance. At that time the remote control distance may be shorter. The battery shall be changed to be a new battery every half a year.

Theory of Operation: Put a 12V alkaline battery into the battery cover (battery polar +/-) Press A for the winch running forward, Press B for the winch running reverse. The remote control distance will be about 5m. The RF signal is 315MHz. Circuit Description: The 315 crystal generate signal and transfer to coding chip. There is tow codes. Then the coding signal will be sent to the triode and transmit to the space by integral antenna. Two codes are controlled by button “A” and “B”.
