TM4TMP3FT2FM TRANSMITTER

Warning: This device complies with part 15 of the FCC Rules. Operation 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. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: --Reorient or relocate the receiving antenna. --Increase the separation between the equipment and receiver. --Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. --Consult the dealer or an experienced radio/TV technician for help. Modifications not authorized by the manufactures may void user’s authority to operate this device.

TMP3FT2 Circuit description 1. The 3V voltage that provided by 2 x AAA batteries provides the power for PLL IC MW_S5 after it’s been stabled by regulating circuit (be made up of Q2, Q4, Q5, R6, R7, R27), then the unit would be standing by. Once the switch S1 be pressed, PLL IC MW_S5 start the electronic switch to power for the whole unit, when the OSC circuit (be made up of D5, L5, Q6, R13, R14, R19, C15, C16, C27, C28, C29) start to work, with the vibratory frequency is around 98.80MHz. After be sampling by PLL IC MW_S5, this frequency will send a tuning circuit onto BD910 to make the vibratory frequency be stabled at 98.8MHz, at the same time, PLL IC MW_S5 will supplier the power for D1. Been increased by class 1 enlarging circuit, this frequency will be sent out through inner antenna once the tuning wave been removed by high frequency removing wave circuit. While pressing S1 in turn, PLL IC MW_S5 will send tuning voltage to make the vibratory circuit at 99.0MHz, 99.2MHz, 99.4MHz, meanwhile PLL IC MW_S5 will supply power for D2, D3, D4 in turn. 2. While the unit working, the audio signal that input by audio inputting wire will be adjusted to BD910 by impedance matching network, then BD910 will modulate it to OSC frequency then send it out. 3. While the unit working, PLL IC MW_S5 will check the audio through audio testing circuit (be made up of Q8, Q9, D6, R22, R23, R24, R25, C33, C32). When there’s no audio be input, it will start to time, and if still no input audio within 15 minutes, PLL IC MW_S5 will off the electronic switch, then the unit will stop working.
