3. The welding installation considerations, follow these steps:
1. The components weld the front plate, from low to high principles, namely the first low welding components, such as capacitor, resistance, diode, etc.
2.Welding IC socket, connecting blocks, finally socket, adjustable potentiometer.
3.The back with a diagonal cutting pliers to shorten the pins as far as possible

4．Debugging steps:
1. After finishing welding on IC, XR2206, pay attention to the direction of IC, add could damage the chip!
2. Check the IC if against, like anti please timely correction.
3. Plug in the power supply, power supply for 5.5*2.1 port, inside and outside is negative polarity. For 9-12 V power supply voltage. The waveform cannot be stable for more than 12 V

5. Use the step:
1. J1 jumper cap plug in, SIN/TRI blue terminals output sine shaft (Note J1, J2 can only insert one)
2. J2 jumper cap plug in, SIN/TRI blue terminals output triangular shaft (Note J1, J2 can only insert one)
3. SQU blue terminals output pulse
4. AMP: sine wave, triangle wave amplitude adjustment
5. FINE: Frequency fine adjustment
6. Rough: Rough setting frequency
